new eZip motor

[DAND214]

So happy you didn't set him up with LiPos!

So now what will you do? All mini bikes.

So here we go again, chain drive. Why?

It's good to hear your still kickin.

No dan in fact I will be looking for a 26" bike for the 1,500W rear hub motor and you guys can help me to pick it out. I will have a place to lock it up downstairs on my front porch. Also these stairs are a lot wider and I have a landing at the top too. It will be much easier for me there. I will be moved in by monday and be getting half of my security which can go towards a new 26" mountain bike with disk brakes. Thanks.

LC. out.

 

[latecurtis]

When I order the 1,500 rear hub kit and controller I will order the 65T spoke kit for the 24" bike. That bike is already built and all it needs is proper gearing for 30 mph.
That and custom brackets to make brakes work on a 24" frame for 20" wheels.

The Currie will also get another motor and be built back the way it was. I will be scrapping metal with the van so should have extra money. I need to finish everything up with this move tomorrow. Thanks.

Just wondering how long the kit will last with SLA in someone else's hands who hasn't learned the pitfalls of SLA yet. Best he does join and read this thread.

Get a MAC - 8T or 10T, depending on your voltage. They can cope with 1500w easily. Though at higher powers, the clutch and gears need occasional maintenance.

 

[DrkAngel]

SLA?
Why would you inflict someone you care about with your sketchy weird, complex, octopoid, Snagglepuss Slabatt rig?
Lead acid batteries are heavy, inefficient, short range, short life, require knowledgeable care and in practical use ... are very expensive!

Schwinn with the 48V 30A controller:
At full throttle will draw 30A from 10Ah batteries ... until near top speed = ~25mph, which:
Outputs less than 20% the usable range of 10Ah LiPo
Outputs less than 10% the usable range of 10Ah LiPo when discharged to only, the recommended, 50%.

1000w front drive ... for a camp?
Not geared for slow speeds or climbing hills ... ?
Front tire is liable to spin on dirt, mud, up hills etc ... putting him into the ground!

 

[latecurtis]

I could give him the LiPos Dan gave me but he would need to learn about LiPo and need to know how to charge them etc. I will get him to log on. I think he registered but has not posted yet. I will see if I can get him to do it now. I am not quite finished moving yet and John is leaving to go back to Ohio this afternoon. Also he is not taking the bike yet. He is planning on coming back to pick it up in two weeks so that leaves some time to do things right.

 

[latecurtis]

sanman say thinking of joining after all i own one .cowboy164@icloud.com

 

[latecurtis]

That would be him. I am thinking about giving him the Skycharger and learning how to use the mega charger I got from Dan to charge LiPo. I only used it for SLAs, never LiPo but can figure it out.

DA. When he picks up the bike and on his way back can he stop and see you and I will give him the bullet extensions for you to fix the packs Dan sent as I rigged them with the ice cube tray etc. He is a good guy and I don't want him to get hurt either. I would order the other torque arm but have not changed my address yet.

He wants me to start building bikes with hub motors and has customers in Ohio to buy them so since it is not for my personal use I will need to start listening and do things right. Thanks and keep posting as he is having a little difficulty as learning computers so will be logging in with my info for now. Please help him. thanks.

Paid $200 extra for insurance on that van until June 26 and either Johnny took back the plate when he went back to Ohio or it fell off somewhere or it got stolen. Lost his number and the phone only works about 1/2 the time. Once I move I will have no phone or internet. Also probably going to lose my security.as I did not meet the deadline as everyone around me are blithering idiots.

He probably wont show up to buy it anyways and as far as it spinning out putting him into the ground I highly doubt it. If he is easy on the throttle and don't go on muddy dirt roads with those tires he should be fine. I never had a problem with it spinning out. I don't see or agree with that statement. If a person knows how to ride a bike chances are that person will be fine.

The only time that bike ever put me down was when I was riding it in the dark at a good 12 mph and hit a broken off section of the road and I did get a little banged up that night. My ribs were sore for weeks. That was the fault of me for not having a light and going too fast. Not the front hub motor. Thanks.

Please note from 1st post on page.
A minimal pedal contribution will increase over-geared motor hill climbing speed considerably!
The effort required to propel a bike on level street at 10mph, (<68w), added to poorly geared motor, will increase hill climbing speed from 4.1 mph to 10mph+.

This saves about 60% the battery use and prevents dangerous motor overheat!

 

[latecurtis]

paid $1200 for a van I cant drive now. I know he took the plate back but he wont admit it. I got totally screwed on the security also. Paid a homeless guy to do work there and getting nothing. However payback is a bitch. landlady over there was going to call the police. Homeless guy will be floating in the river soon.
Sick and tired of getting screwed over. Took the guy off the street, fed him and gave him money to do work and i get screwed.there will be a lot of blood spilled over this.

Not selling the Schwinn. Was supposed to have the van legal until June 26. i guess i got a sign on my back and forehead saying screw me over please any way possible.

Then people wonder why people get guns and start shooting people. i know why. Because some people just want to be left alone and not bothered. i did not want to move in the first place. i really want to find out where the landlady lives. this is far from being over. thanks.

WoW. Can't believe someone would sell you a vehicle and then take the plates off of it so you can't drive on their dime. How Dare Them.

Guess you could take title / bill of sale to Department of Motor Vehicles and have it transferred into your name and get current plates. You'd show them.

I'm sure you didn't expect to buy a car / truck and get to drive for free Right ?

Plus didn't you want to move to get away from living on second floor and having to push / carry bikes up and down stairs ? Problems with hitting walls with bikes and making more damage ?

Guess you could sell the van and get your money back ( you did pay for it right ? ) Would be a win win situation for you. You'd show them.

Good luck with the rest of your move and hoping to hear more about your E-Bike building .

 

[Sunder]

Gotta say, I'm with Ronnie on this one.

When you sell your car, you can transfer your plates to your new vehicle. Plates CANNOT be transferred to the new owner of your old car.

http://www.dmv.org/ny-new-york/license-plates.php

So the owner did the only legal thing, and you reckon he's ripping you off? If he didn't keep the plates, you could park anywhere you like, speed, ignore lights, even run over pedestrians, and he'd be liable.

 

[latecurtis]

He asked me three times "Please dont let anyone else but you drive this van.

I told him three times I promise I wont. I will finish the move and park it. i got a car to drive around anyway. i did not lie and would have done a couple of trips and that would have been it.

The car is legal as the original owner is in jail for DWI. the new title i have is in the name of my friends wife. My friends father is the guy in jail and probably wont ever drive again as 4 DWIs. She drove the car for about 8 months after the DWI and he went to jail about three months ago. I got title signed and bill of sale. Title is in the wifes name registered and insured to her but signed over to me with a bill of sale. My license is valid and clean but in NY if no insurence for 6 months you are in high risk like you never drove and are 16. I am not paying $200+ for insurence $100 for title fee and taxes. i am on a fixed income and disabled. Not happening!

We share the car as her two sisters use it when their car breaks down to go to work. All home health aids.

However when the guy got the DWI the original key was lost or took by police. Not sure but was a coded key. The key I got is a cheap copy that works most of the time but sometimes wont start the car. Anti theft light blinks and have to wait about 20 min to start it.

Ended up pushing a big red shopping cart to finish the move for about 5 miles total awhile some bum i paid , fed and put up for nothing sat on his ass drinking and now i get screwed out of the half months security i need to get furniture for this place.

 

[latecurtis]

took the homeless guy off the street fed him and gave him beer money to do the job and now am screwed out of $200.

My people rode by today and the homeless guy was sitting out on the porch with the bitch downstairs having a beer.

got screwed in every direction on this one.

Why I play pirates tides of fortune a lot. It takes my mind off of stuff, i got four havens. two in each server. Come check out the game.

i got two captains to talk to. I am in two brotherhoods with two havens in each. lol.

As the Hub Motor Turns and the LiPo Fire burns. Unsafe.

You guys are right. The Schwinn is unsafe at a camp site on muddy roads. All the more reason i should not sell it to johnny and keep it all to my self. Thanks.

I will order another 10.0 6S pack.

LC. out.

 

[Sunder]

Speaking of unsafe, I just installed a BMS Battery BMS onto my 16S LiPo.

My LiPo has some very unbalanced cells, because they use 2 x 4S balancing leads, and I left the 4S balancer plugged in for a week once. Long story short, half the cells got drained by the balancer, half didn't.

Anyway, I figured a proper BMS should balance the cells before allowing any of them to get above 4.2v. Nope. Top cell reached 4.5v before the charger cut off.

Disconnected the charger and balancing now, but damn, that was close. Probably shortened the life of my cells somewhat too. Hope they don't die, but if they do, I'll just get some Turnigy 12Ah batteries. Larger than I need, but they're the same price as 5Ah cells, just 2C instead of 10C. But 12Ah @ 16S is 1.4kw anyway. I set my limiter to 800w, so I would only be taking about 1.2C

 

[DrkAngel]

Well, I gave up on any form of BMS about 7 years ago.
I came to view as ...
An expensive security blanket ... false sense of security? (!)
or worse
A Band-aid for a defective pack!!!

Typical BMS charges pack to specific voltage, then bleeds down higher voltage cells or banks.

BMS with equalization will charge pack to designed voltage then bleed down cells higher than rated.
If 1 self-discharging cell ... causing 1 poor bank,
BMS will charge pack to proper voltage,
then bleed down all good banks,
then charge pack to designed voltage,
then bleed down all good banks,
etc. ... in perpetuity ... !

Now you can purchase a top quality "intelligent" BMS ... but that might cost more than battery ?
I prefer testing and rating of all cells for a "proper" pack build that requires no BMS! - In conjunction with Bulk charging and Low voltage monitor-alarm.

 

[Sunder]

It's the first BMS I've used, because for a 6S pack, it was easy to just balance charge once a month.

With an 8S pack, it wouldn't be difficult if it came with an 8S connector, but it came with 2 x 4S connectors, so my balance charger couldn't balance them. Using cell log style balancers, each group of 4 would balance, but not the groups with each other.

It is definitely a bandaid to good care of pack, but a bandaid is better than letting it fester out in the open.

 

[latecurtis]

As the Hub motor Turns and the LiPo Fire Burns. LiPo or LIFEPO4

Speaking of unsafe, I just installed a BMS Battery BMS onto my 16S LiPo.

Not sure but I thought BMS (battery management system) right? was for LIFEPO4 not LiPo.

Everybody knocks my way but it does work. I simply use balancers. I got four I think.

I always balance charge every time and new packs need to be balanced with a balancer after balance charging. Especially before combining.

I am running 16s@22.2V two 8.0 packs combined and they run perfect even though they came with a low cell and I discharged below 3V. One balancer does the trick. Two would work for 44.4V.

I am not familiar with BMS but really dont see why you would need one unless running LIFEPO4 when balancers are so simple to use. But what do I know as I am always wrong about everything anyways. Thanks.

LC. out.

 

[Sunder]

You can get BMS for LiPo, Li-ion and LiFePO4. Technically, you can get BMSes for anything, but many chemistries don't need it. For example Lead Acid can be balanced by intentional overcharge. The high voltage does boil the acid in the overcharged cells, but it properly charges up the lower cells. When the acid cools, all cells are at max voltage. Try that with any Lithium chemistry, and the best you can hope for is a fire.

Balancers should be sufficient if you're diligent about using them, AND your packs can be balanced as one. If you can't balance your pack as one, how do you get each half, third or quarter to talk to the rest of your pack?

So in my case, I have an 16S pack which is actually 2 x 8S pack which is then further broken down into 8S bulk charge, and 4S + 4S balance . There are no bulk charging cables for the 4S, just the balancing cables. If that doesn't make sense, have a look at the photo below:

The first 4S is at all balanced at 4.2v, the second 4S is balanced at 3.8v.

If I bulk charge, the 4.2v half will overcharge, while the 3.8v will charge properly.

The only way I can rebalance that pack is either:

1. Break it up into genuine 4S packs and balance charge everything to 4.2v; or
2. Install a 16S BMS, and get it to balance everything in one go.

 

[DrkAngel]

Guess I am just lucky?

I build using recycled cells ...
so I test and balance build all my own packs.
Never needed to balance charge any of my batteries!

Builds are precise enough and I treat them properly ... so they never need balancing!
Always equal bank voltages at full and empty!

I'm guessing you've never bought Zippy. Never again. I've had two sets of Turnigy - Both perfect, balancing once every 3-4 months was enough, and even then it was token. I've had one set of Multistars - They're very low use, since they're way bigger than I need, so I only pull them out for long rides. But never had to balance those.

I've had two sets of Zippy. Both have needed very regular balancing - 1 month usually means cells are out by at least 0.05v. And unfortunately due to the design of their balancing plugs, they're very hard to balance.

Never going Zippy again, but I'm not quite willing to throw the ones I already have out.

 

[latecurtis]

Thanks for letting me know. I wont buy zippy either. I buy off of e bay even though I was advised against it. I never saw anything like that though. Two balance cables with I pair of bullet connectors. Who's bright idea was that.
Also why does it say 4,000 if it is two 8.0 packs. The whole thing is very confusing.

1. Break it up into genuine 4S packs and balance charge everything to 4.2v;

that is what I would do then hook up balance Y cables after recombining them and they should balance and all stay the same voltage I would think.

However it is rather complicated and I may not be seeing the whole picture here. Thanks.

8S = 8 Cells in series.

4000 = 4000mAh = 4Ah.

I steered away from your option, because the less connectors, the less likely you will get connection issues. BMS is just install and forget.
