Enerkey 12V/24V BMS 3s-8s 200a High Current BMS for 28.8V 29.6V Li-ion/Lithium 24V 25.6V LiFePO4 Battery Pack
Wide voltage compatibility
Intelligently adapts to 3S to 8S lithium battery packs (nominal voltage range: 11.1V-29.6V), one board is universal in multiple scenarios, reducing the complexity of user selection.
200A continuous high current output
Supports peak 600A high current discharge), meets the high power consumption requirements of power tools, power equipment, etc., and avoids overload damage.
Seven-fold safety protection
Integrated overcharge/over-discharge/overcurrent/short circuit/temperature protection (±2.5mV voltage detection accuracy), real-time monitoring of battery cell status, and extended battery life.
Intelligent balancing technology
Passive balancing (balancing current: ±80mA) reduces the voltage difference between batteries, improves the overall performance of the battery pack, and prevents a single battery cell failure from causing a chain reaction.
Industrial-grade durable design
Aluminum alloy heat dissipation shell (IP65 waterproof optional), -20℃~75℃ wide temperature range operation, adapt to harsh environments (such as outdoor energy storage, electric vehicles).
Technical Parameters (Specifications)
Applicable battery type: Li-ion/LiFePO4 (lithium iron phosphate)
Balancing method: passive balancing
Customizable communication interface: UART/RS485 (supports remote monitoring, optional Bluetooth module)
Installation method: plug-and-play terminal block, compatible with standard battery pack interface
Application scenarios (Applications)
Electric transportation: electric scooters, electric bicycles, golf carts
Energy storage system: solar energy storage, UPS backup power supply, RV battery pack
Industrial equipment: AGV robots, medical equipment, drone power system
User pain point solution
"Multi-string battery packs frequently have single-cell over-discharge, resulting in overall failure"
Accurate voltage monitoring + dynamic balancing technology to ensure cell consistency.
"Frequent power-off of the protection board when high-power e starts"
The millisecond-level overcurrent response threshold is adjustable to avoid false triggering.

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!
