Battery Packs - Where to buy them

[Jason27]

AllCell Technology in Chicago makes great batteries. They incorporate a proprietary PCM (phase change material) that absorbs excess heat and allows for higher performance/longer life. I've been using one of their 36v 15Ah packs with a 750 Aotema front direct drive for 3 months with great results. They also warranty their packs for two years. If you're interested, I can refer you to a shop in my neighborhood that is an AllCell dealer/shipper.

Agree 100%. I bought my battery pack from Chicago Electric bikes and it is still running great since 2011. So its almost been 3 years and no difference in performance. The prices are higher, but the quality and service is excellent.

I always bought Chinese LiFePo4 batteries other than getting the BMS far too lower wattage then replacing BMS have had good service from ---
BMS battery , Greenbikekit , & battery bikekit . Having trouble at the moment with shipping to our bottom of planet country New Zealand-- are there any other
battery supply people who others can recommend.-----By the way one of my past batteries is near 9 years old as don't ride every day .
Proves LiFePo4 are cheap over the years.

We're wanting battery in carrier type pack , seems ping only have the square shrink wrap ones .. Its Definitely better with key operating
turn off as with our type kit there is never a total off until battery disconnected..

Are you just looking for LiFePO4?

I've been getting 18650 cells from tumich. Sea shipping takes 2-3 months but well worth it and very cheap (both cells and shipping).

looks like i'l have to buy ebay but have to add 15% tax as price marked at real price . They can be risky with as bms can be to low a amps .
i think this motor is about 300w.(36v)Usualy am buying for 500 & 24v & this is big amp for most 24v (have replaced a fair few BMS's)

thank you eva-macheal
thanks for the good information .
I just bought one on Ebay hope it gets to us have tax yet on it to pay etc I've built up the cells & BMS with the large screw headway ones AH does never seem to be as each cell is claimed & Ihave had problems as with the way I made the pack.Also i wish one could buy a key operated high amp switch for simple connection .
As an electrical guy said to me once -kev your'e playn round with nothing ya know about. Don't make a dime at what i do but if it werent for these batteries I'd not be biking I'd propably have a muss'el vintage pony. (car)

Where can I get a 14s2p 18650 pack? I ordered the one Luna sells, but they seem unable to ship it and I'd like to find a more reliable source for future orders. Is there a vendor that will make a custom pack like that for me?

I was running 3 SLA battery I got about 300 km out of it , and now I learned my lesson, since the SLA battery now dead not even 5 months in.

If I want to go with the cheapest option that is not SLA,

is LIPO from hobby king will be the best choice. price wise. please Keep in mind I need a battery and charger combo.

I have a pretty good knowledge on how to wire lipo battery to get the voltage I need. (may need a little bit of guide as I never done it for bike, I did it for hobby RC Car )

But I am clueless as to how to charge it , ideally I want to charge them properly but not too cumbersome as to having multiple charger for each battery. as long as the charge setup only use one AC 110V outlet.. it would be great.

or is there general consensus among forum members as to where to get battery online source that gets me battery and charger combo and at a good price too.,


spec of the battery I need is 36v (anything less than 10Ah and above 4Ah will do) and a charger,..


thank you

No, good God just get a bottle battery and let it do the battery management.

Hi all! Any idea of where would be the best place to buy new 18650's in bulk. Planning on a 30 to 60kWh project.

Thanks!
