With my cells so far I created 2 12S packs via compression with a cell_man high power BMS. It worked well , but with the diodes &
wires it was somewhat a pita to use. Not to mention only good for my cargo bike and not my mountain bike because of size.
So I had ping send me one of his high rate 20S BMS which is a signalab. I really liked the lights and how this BMS bleeds off all the cells.
The bad part is the most I am seeing AMP wise with it is peaks of 50-60 which is only on initial acceleration.
I am thinking now I may use the BMS just for charging and bypass the BMS for discharge so I can get the most amps from the a123 cells.
Anyone see a problem with this ? I have an email out to cell_man asking if he has a 20S or 24S high rate BMS and I may also go that route
tho the lights are nice.
Just wanted some input on bypassing the BMS for discharge.. I think I know my own answer , but wanted to be 100% thanks.
2nd question should I be concerned with regen on any of these BMS ?
May not look pretty. I used saran wrap for 1st layer. Filament packing tape for 2nd and duct tape for outer.
covered it all up so I can drop metal parts and not worry.. Need a 12x8x7 plastic case now.. Cool thing is it fit in my rear topeak trunk bag.
