Default Re: Lifepo4 Pack Specificatons

I was able find the rating for the cells. The manufacturer says the cells are rated for 3C continuous and 5C~10C peak without the BMS.

BobBoyce, thanks again for the added information. Its very helpful. I definitely have some other things to consider before i pull the trigger and order these cells and the battery kit.

I need to make sure:
  • I don't screw up my controller by shutting it off before it writes to its internal memory
  • Have a way to gently bring the cart to a stop if i have a cell or BMS fault condition (as noted in one of the other threads that an abrupt stop at 20mph would be a big problem)
  • Build a manual override like BobBoyce did for his 2008 RXV
  • Adjust the BMS specs to handle the required motor amps. I don't want this awesome battery pack to under perform

Do you think i should have a BMS built state-side or via a well know BMS manufacturer rather than get through the chinese cell manufacturer? Any recommendations on a good BMS company to work with?

thanks,
Myles
