There is NO shock at 48v, unless your hands are wet and touch the metal connector part. The shock is nothing!

Have you ever got a shock from 120v? That one wakes you up this one is like licking a 9v battery.

The only worry about connectors is hooking them wrong. I did it 2 times, both times it was a real eye opener. No flames just sparks and destroyed connectors.

DrkAngel has made it as easy as possible. I had made it that way but I guess you didn't understand it at the time.

I am still using 4mm bullets on the LiPos but Andersons on the controller. You will normally get a spark when you hook up the controller but not a concern as shock wise. You kinda jump in the beginning but get use to it after a while.

I have been pricing the connectors. I also got an idea. If I can get a really good pair of rubber gloves electricions use that are shock proof I think i may be able to do without the switch. Latecurtis.

Plugging powered 22.2V battery into 6s balance charger can produce a microscopic mini spark.
Plugging 44.4V battery into a powered 44.4V bulk charger can produce a very low power spark ... ≤ 6V.
Plugging 44.4V battery into your 48V controller will produce no spark ... unless you left the switch on!
Switching pack from 22.2V to 44.4V will produce absolutely no spark! (if not connected to charger or controller)

However! ...
Plug in anything backwards and you will have substantial sparks and heat ...
melted connectors
melted metal
destroyed controller or batteries
etc. - most programmable balance chargers will simply disable and display "Reverse Polarity"

So ... learn how, and start using your multi-meter, it is a most basic and essential tool for any electrical work. KISS ©®


And please ... add a fuse!
Can turn stupid expemsive mistakes into cheap valuable lessons.

Trying to clarify 6s2p
Simplify all diagrams by combining pars of batteries as they will be used. - 6s2p
Pos & Neg power Y and balance Y to 1st create 6s2p bricks.

22.2V charger

Except for the balance connectors ...
After you pair up into 6s2p, KISS ©®
Charging and running this 22.2V - 44.4V LiPo is exactly the same complexity as 2 - 12V SLA batteries = 24V and a 12V charger.

Oops!

Balance charge all cells before combining into 6s2p.

Alternatively, confirm all individual cells, in all packs, are of same voltage. - (multi-meter!)

I don't know if that will be possible. I plan on combining the two packs inside the lipo bag. However I guess I could just extend them all ( all power connectors ) out of the bag and the metal box so I can check each cell with the multi-meter. This is my diagram (without a switch). I will use thick rubber gloves to make the connections. Please see new diagram. The wires coming out of the Lipo bag including the balance wires will be gorilla taped securely to the bottom of the metal box as well as the Lipo bag so there is no movement of the wires coming out of the Lipos.

I am getting kicked out of the library again as they are closing. No internet access until Monday. If you guys want to help me I need all these plugs from the cheapest source possible.
If I have to run each power wire outside of the box I will need 4 - 12" bullet plug extensions also. The only way I will solder and make these wires myself is if I can get everything I need in one kit. Ordering everything separately would be insane and probably forget to get everything I need. I know what plugs I will need. Now its about getting everything as low cost as possible. I would like to be able to order Monday. Please post links if you can. Thanks Latecurtis.

You check the cell voltages at the balance plugs.

No need for rubber gloves! You're working with 50V ... not 50,000V!

HXT 4MM Bullet
Almost certainly going to have to make your own extensions ... or email this seller and request custom item?

 

[latecurtis]

I have no idea how to check voltage with a balance plug. i thought it was done with a multimeter and the power bullet connectors. That means I will have to extend all 4 balance plugs out of the lipo bag. Do I still need to extend all 4 power bullet connectors out of the bag also? I will take your word for it that i wont get a shock but am getting the rubber gloves anyway. It cant hurt. I dont want to do another cheap tape job and never soldered much of anything or did shrink wrap insulation. I dont know if I can do a professional job. Are you saying they dont make bullet plug extensions. I know they make parallel and series plugs. I saw them on google images. i will look again. Thanks Latecurtis

Does the bannana plugs plug into the bullets from the Lipo. If yes then I can order these.

I will still need the 4 balance plug extenders though right. I have not completley givin up on the switch but am willing to comprimize for now and use rubber gloves so I can at least charge the batteries soon so they dont lose capacity sitting around. I would like to do a test run with the front motor also. The bike and Lipos and all the stuff is over to dougs house. I really dont have room for two e bikes. Its a small apartment and the Landlady wont let me keep one downstairs.

What I really need is to sell both bikes and use the money to build that chrome chopper with the 1500 watt fork motor and get LIFEPO4s to run it. The last time I took out the currie I put a big scrape in the wall in the stairway. The Trek wont be much easier. There just is not enough room for a 26 inch e bike on my narrow stairway. The landlord already screamed at me for the damage to the walls. A 20 inch chopper all aluminum with a high seat and high handelbars and that 7 pound 1500 watt brushless motor on the forks and a detachable LIFEPO4 pack mounted to a rear rack comming off the seat pole like what I had on the specialized would be ideal. Under 50 pounds total with batteries and small enough to carry up and down stairs is what I really need.

 

[latecurtis]

Anyway please post a link for the balance plug extenders. they will need to be about 14 to 16 inches long. I guess I will need 4 of them. Also let me know if those plugs I posted will work to extend the power connectors. I will be at the library tommorow.

Thanks. Latecurtis out.

Check all cell voltages ... use multimeter to measure between each of the 7 wires on the balance plug.
If not equal, use balance charger to fully charge each pack individually.

Well ... then, if all voltages very close, use the power Y and balance Y to turn 2 - 6s1p into 1 6s2p then do the same thing with the other 2.
Should have been done already. Posted specific directions 3 times ...

Measuring power bullet connectors will measure pack voltage not cell voltage ...

Banana plugs are both male, designed from charger to battery.
if set up properly, your extension should be Male & Female on one end to M - F on the other.

Once again ... powerfull front hub motor is suicidal! and Problem is amplified greatly by going chopper style!

I already showed my brother in law Mark. He is a welder. 18 years experience. I showed him that video and my idea about the fork motor. He is going to help me build it. All aluminum and polished. It will go about 40 mph. A 7000 rpm motor would not work with a 26 inch wheel as they dont make a big enough sprocket. Thats why I gave up on the idea before. With a 20 inch wheel though and your formula DrkAngel it will happen. And I see it going about 43 mph.

I will be selling one of my 26 inch bikes. probably the currie if i can get the trek running with the front kit. Thats why i want to get this Lipo thing done because the front hub motor Sunder sent me is the 26 inch bike I want to keep. i dont need three bikes. But as much as a headache these Lipos are I would love to just sell or trade everything to do the chopper with 4 LIFEPO4s. If you are interested DrkAngel I will get an aluminum 20 inch bike and have Douge raise up the seat and the handelbars, Then have Mark weld the forks and then bring everything to you DrkAngel and we will put the chopper togeather. I will give you the trek with the front kit and sell the currie to get LIFEPO4s.

I would be very happy with a shiny 20 inch aluminum chopper that goes 43+ mph and about 15 miles with 4 LIFEPO4s. Plus ease to carry upstairs and it wont take up much room. Think about it DrkAngel and let me know.

Is that the right extention for the bullets comming from the Lipos. Will it plug in to extend them out of the LIpo bag. Thats all I will need to know. Please let me know as I want to order them tommorow. Thanks Latecurtis.
