3S 4S 5S BMS 12V 16.8V 21V Pcb Printed Circuit Board for Li-ion LMO Ternary Lithium Battery Protection Circuit Board
lithium battery protection board Features:
It is our lithium battery protection board specially designed for lithium phosphate, ternary lithium battery, lithium cobalt oxide, and lithium manganate battery packs. This protection board contains 3 strings, 4 strings, and 5 strings lithium battery protection boards (the general version adjusts the corresponding components according to actual needs), adopts mature protection circuits, special ICs and supports disconnection protection, high-current ultra-low internal resistance MOS ( The internal resistance of a single MOS is as low as 3 mΩ), with complete and stable charging and discharging protection functions, battery hardware balance processing, appropriate balance current, reasonable balance heating, and does not affect battery pack performance.
PCB borad description:
- This protection board is 3s 4s 5s in common use lithium battery protection board (you can adjust for how many strings to be used), the default delivery is 4S ternary lithium.
-
Common use for "same port" and "different port", the protection board uses 15 high-power of ultra-low resistance MOS tube (discharge of 8, charging of 7), in the same port mode can support the continued discharge current 60A, charge current 60A; split port mode discharge current 80A, charge current 60A.
-
It is definitely not a low-power MOS on the market. Our single MOS transistors has an internal resistance of 3 mΩ.
Application:
- Specified chip, stable performance, support disconnection protection, over-current protection, over discharge protection, overcharge protection, with balance, etc.
- Can use for LMO.Ternary lithium battery.LCO(3.7V)battery packs etc.
