Enerkey Hardware BMS 3S 100A 120A 150A 200A Li-ion/LiFePO4/Lto/SIB Battery PCB Board with NTC and Balancing
Product Name
3S-8S 200A high current lithium battery protection board (BMS) |
Intelligent balancing | Industrial-grade protection
Core functions
Wide string compatibility: supports 3S to 8S lithium battery packs
(nominal voltage 11.1V-29.6V), and is Compatible with lithium iron
phosphate (LiFePO4), ternary lithium (Li-ion), lithium titanate
(LTO), sodium ion (SIB) batteries.
200A continuous discharge capability: peak current reaches 600A,
meeting high power requirements such as electric vehicles and
energy storage equipment.
Seven-fold safety protection: multi-dimensional protection such as
overcharge (±4.25V accuracy), over-discharge (±2.5V accuracy),
overcurrent, short circuit, temperature (dual NTC monitoring), etc.
Dynamic balancing technology: passive balancing (±80mA) reduces
cell differences and extends overall life.
Applicable scenarios
Battery exchange cabinet battery pack (supports 3-8 strings of
adaptive configuration)
Outdoor energy storage system (IP65 waterproof housing optional)
Industrial equipment (AGV robot, medical equipment)
Storage and transportation mode sleep
Automatically enter low-power standby state (<3μA) during
transportation to prevent accidental discharge during
transportation3.
TVS surge protection design
Integrated transient voltage suppressor (TVS) can absorb 8kV surge
current and resist voltage spike shock.

Wiring precautions:
1. Installing the protective board requires a certain amount of
technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad
position to the total negative terminal of the battery (the B- wire
should be soldered to a short and thick wire) and solder the wired
terminal to the battery pack first, and then insert the protective
plate.
3. The connection between the battery terminal B- and the
protection board terminal B- should be short and thick, otherwise
it will cause the protection board to charge and discharge in
advance and malfunction.
4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
