Re: Home depot ego battery packs dropped in price. Echo also

I just looked at Luna Cycle 52V 12Ah pack for $460USD + $40 S/H = $500USD/$700CAD Which is on par with the price of HD's EGO pack. Their 56V 5Ah is $298CAD with standard charger $80 or their 30 minute charger $130CAD. The battery works out to $60/Ah I just installed these batteries from em3ev 52v 1...

Re: Recent build: Pikachu

Either of them laced in a 700c wheel? :) That would allow me to throw it on the back and test it out without tearing down the front wheel...just swap to the controller and compare the torque difference. Yes, I have a 10t in my girlfriend's 700c road bike (I've rode it a bunch). Running on 14s it ge...

Re: Recent build: Pikachu

Looks good. I have used MAC 8t and 10T rear motors here in Portland. I didn't know the grades where that high around here! I've went up to Council Crest on my commute from downtown to Multnomah village. Motors seem fine with it(and I believe it's the highest point in Portland).

Re: Motorizing a Catrike Speed- Best option?

Still saying to go with em3ev. The issue is in how long it takes to ship from China, especially now that they seem to be back ordered on the batteries. My last two battery packs seem to have taken 3 weeks to a month. Paul is a great guy though and Moon answers every email within like 12 hours. I'd r...

Re: Safe speeds on non-suspended, 20" front wheel, LWB recum

Honestly I would think 35 mph would be a good speed depending on where you live. I say 30-35 just so you can get out into traffic on a city street when you don't have a bike lane. It makes you much more confident in those situations. I've generally been going 20-25 mph on my commutes/and joy rides a...

Re: Motorizing a Catrike Speed- Best option?

Have you thought about a MAC kit from em3ev? The geared hub motors are generally lighter. You would have to check with them on a 6T motor wind. With a 20" wheel I would think you would get 30 mph (50v battery) out of it. I just did a build with a kit from them. With the motor and battery it was at $...

Re: Updated battery info 33g & questions

It's for my girlfriends road bike/commuter. I can't believe the small triangle pack actually fit in her step through. She was getting her 24 mile commute done on 5 year old 12s 10ah Lipo so I imagine this new pack will get her almost 60 miles!

Re: Updated battery info 33g & questions

Strange, some of the specs on the sheet look like they're for a 50v pack pack not a 36v one, for example the charge at 58.8v. I think I'd focus on the measured column. The other columns just seem to be related to the testing procedure. I'm not sure if the impedance of 74 milliohms is good or bad tho...

Re: Updated battery info 33g & questions

I ordered some 33G packs from him. 2 small triangle 50.4V 18.6Ah ones. He's been great in the past and they are responsive to emails.

One pack is already on its way.

I am also trying to get away from the always-be-careful lipos.

Yeah, looks like I am down just 1 pack since I had a couple spare ones and I was able to salvage 5 that didn't go below 2.7-2.8v. I'm going to throw the others out.

Re: Mac 8t with Sunthing 48V 15Ah?

Ok, I usually do a bulk charge anyways I.e. I do not hook up balance wires to the iCharger. I tried to charge up a pack that was all at 2.8 and I can tell on my cell log that it stayed in balance up to 3.6(then I stopped charging). Maybe I should just bulk charge the other 4 packs that are still in ...

Re: Mac 8t with Sunthing 48V 15Ah?

Humm, that's interesting they are at 2.8 v per cell for most of the packs. One bank of 4 packs has 1 cell at 1.6v. Maybe I should try to charge them. The iCharger doesn't seem happy though (no bulk charger).

Re: About to order 48v15ah li-ncm from BMSBattery, should I?

True, I had an issue or two with my order. It was a motor kit. For one the wheel was not even close to true. For another there was something wrong with it as evident from the terrible noise it made when trying to accelerate.

But that was with a hub motor not a battery!

Re: About to order 48v15ah li-ncm from BMSBattery, should I?

I think it was them who sent me an e-mail after I ordered telling me it would cost extra for shipping. That was just with a motor in rim. I can't remember how much extra they wanted (even though I already paid for shipping when I ordered). That was a couple years ago though so maybe they've changed ...

Re: New US ginormous giga batteryplant

So the argument for hydrogen is that we can switch over to natural gas production instead of gas(because the efficiently drops way down for all other sources). They already said it will cost roughly the equivalent of driving with gas. So why should people switch? Don't you think a lot of people are ...

Re: New US ginormous giga batteryplant

Unless batteries can be charged in short periods of time, distant travel for the masses will be a huge obstacle to overcome. Some onboard / quick fill type fuel may be needed. The cleaner / greener the better. Or just do a battery swap. I think the superchargers are good enough even in the present ...

I admire this move. If tesla wants to release the model e at the volumes they're predicting, they had to do this. They can't even get enough batteries to meet demand of 30,000 model s's per year.
