    Looking for help - 500A peak BMS 12s/16s Lifepo4

    never think that i can use a bms like this (never tried). it's ok with 12v, i think i need something for stabilize 36v or 48v to contactors before kill the coil (they should work in 15% +/- volt range not more) btw a stepdown can do the work

    I present you EVAL v1.0

    great work. was workin on something similar, but no time to advance. i see only 2 limits : cell size (as another one already wrote) and chemistry limited to li-ion due to TP4056

    Looking for help - 500A peak BMS 12s/16s Lifepo4

    I'm looking for reliable 500A peak BMS, peak should be last around 3-5 min. I'm not sure that Daly BMS can handle that (and it cost around 500€) We need a couple to assemble a sample pack for EV. thanks
