I put one of those together. Worked pretty good for awhile, but cells kept dying. I went through probably 6 BMS's the last couple years.

Frankly guys I like the Li NiMnCo batteries better. More stable, IMHO.

I love the form factor. I'm not convinced they all meet their rated AH. And they are expensive.

It takes a little while to learn how to use them but using a rc charger instead of a bms to charge and use lipo alarms for discharge is how to make cells last a long time.

These tools were designed to help you get the longest life from li ion batteries.

I learned a lot about battery pack building on the rc forums.

I glad that is where I learned and did not get caught up in that ebike bms mess. :)

I am still using A123 cells from 2006 Dewalt packs on the trike and they are still going strong. :)

Thanks for the nice links. I've read of a lot of people being dissatisfied with the Hobby King battery's. They claim they don't get many cycles out of them before they start going bad. I don't know if it's the battery's, or something they're doing wrong.

I think those LiNiMnCo are the same kind of battery's they sell at Hi Power Cycle.

I could live with two 10 ah 72v battery's.
