I am making multiple 8 x parallel(lithium iron 18650 3.7v 3400mA) battery packs that should be under 100Wh capacity.
The individual cells are not protected for over current.
Each x8 cell pack will need some kind of short circuit protection >100A , 135A ( 500w )
The x8 cell pack has no BMS.
I don't need charge voltage protection as the x8 cell packs will be connected together in series to make one large 36v battery that will have a BMS.
I'm trying to design a modular battery that is designed to come apart.
I need some protection against the small packs shorting out and going into thermal runaway !
can anyone point me to a design that could achieve the low voltage high current protection ?
Should i used an existing IC and a few mosfets ?
Its for an E-bike that can draw up to 500W peek
