4S BMS 3.7V 100A Li-ion LMO Ternary Lithium Battery Protection Circuit Board Li-POLYMER Balance Charging Board Module

Product Overview:
Product structure: Lithium battery protection plate
Scope of application: lithium iron phosphate, ternary lithium battery, lithium cobalt acid, lithium manganese acid battery pack
For lithium phosphate, ternary lithium battery, lithium cobalt acid, lithium manganese acid battery pack specially designed lithium battery protection plate. The protection plate includes three strings, four series, five series of lithium battery protection board (gm) according to the actual demand to adjust the corresponding components, USES the mature protection circuit, a dedicated IC break protection and support, to import large current ultra-low resistance MOS (single MOS resistance as low as 3 milliohm), has a perfect stable charge and discharge protection function, batteries balance hardware processing, balance current appropriate, reasonable, balanced fever does not affect battery performance.
Technical parameters:
Pin mode:
P-: load negative
C-: Charger negative B-: Battery negative
Practical operation guide
Output current: split 80A; With a 60
Note: Lithium battery should be charged with special charger for lithium battery, do not use lead-acid battery charger, lead acid charging may have high voltage breakdown protection plate MOS tube, resulting in overcharge of the protection plate does not protect.
(1) The wiring method of the three-string branch (refer to the wiring diagram of the three-string branch)
Connect the three battery packs in series according to the connection method of the battery in the three serial connection diagram.
(2) Connect the anode of the charger to the C- of the protection plate, and the cathode of the load to the P-.
Connect the charger and the positive pole of the load to the positive pole of the 3 series batteries.
(4) Refer to the three-series junction wiring diagram and connect the positive poles of the three battery packs with B+, B4 and B3 in order respectively.
(5) Connect the negative electrode and B- of 3 series of batteries. B1, B2, and B- short.
After all the wires are connected according to the 3 series splitter wiring diagram, check whether they are correct and start to use after confirmation.
During the use, when the indicator light on the protection board is on, it means that the corresponding battery pack is in balanced working state (that is, the battery is not balanced at this time).
