3S 4S 5S 3.2V 120ALiFePO4 Lithium Iron Phosphate Lithium Battery Protection Board for Marine Car Startup Copper Bar Ex

Note Ternary lithium and lithium iron phosphate boards cannot be mixedOverview This protection board is a lithium battery protection board specially designed by us for high current lithium phosphate ternary lithium battery lithium cobalt oxide and lithium manganate battery packs for ship machine and automobile startup This protection board contains 3 strings 4 strings 5 strings of lithium battery protection boards using mature protection circuits dedicated IC and supporting disconnection protection high precision independent balanced IC TVS spike protection imported high current ultra low internal resistance MOS single MOS internal resistance is lower than 3 milliohms 410A peak current with perfect and stable charging and discharging protection functions cell hardware balance processing proper balance current reasonable balance heating and does not affect the performance of the battery pack The actual test is equipped with short circuit protection but it is not recommended to go short circuit The short circuit current is very large and it is easy to burn the battery and the protection board Features 1 The user can freely set 3 strings 4 strings or 5 strings select the corresponding number of strings which has been adjusted 2 This protection board uses 26 high power ultra low internal resistance imported MOS tubes 13 for discharge and 13 for charging which is by no means the low power MOS on the market Our single MOS tube has an internal resis
