3S4S5S6S7S8S120A Smart Lithium Battery Protection Board: Redefine high energy efficiency and safety
Core function: Make every ampere "rock-solid"
Super strong current carrying capacity

120A continuous discharge : Provides strong power for power tools and energy storage equipment, with a peak current of up to 300A (2 seconds) .
Intelligent overcurrent protection : Automatically cut off the circuit when the current is ≥350A, and the short-circuit response is <1ms to ensure the safety of equipment and batteries .
Triple safety protection
Overcharge/over-discharge protection : Accurately monitor the voltage of a single cell (overcharge ≥4.25V, over-discharge ≤2.75V), and the recovery threshold error is <±0.05V .
Temperature fuse mechanism : Optional NTC temperature control module, automatic power off at high temperature, to eliminate the risk of thermal runaway .

Dynamic balancing technology
Passive balancing ±20mV: Eliminate battery pack voltage differences and extend overall life by more than 20%.

Technical highlights: Not only protection, but also intelligent management

Multi-protocol intelligent interconnection (customizable)
Bluetooth/CAN/RS485: View battery status in real time, and adjust protection parameters (such as current threshold, balancing strategy) with one click on the mobile phone.
Customized expansion: Support GPS positioning, inverter protocol docking, LED power display, to meet industrial-grade needs.

Industrial-grade structural designSame-port/split-port dual versions: Same-port design: Integrated charging and discharging interface, simple wiring, suitable for 120A high-power scenarios.
Split-port design: Independent charging and discharging circuit, balancing efficiency increased by 30%, suitable for long-term energy storage systems.
Triple-proof PCB coating: dustproof, moisture-proof, corrosion-resistant, no fear of -40℃~85℃ harsh environment.
Ultra-low energy consumption
Static power consumption ≤33μA: standby time increased by 50%, say goodbye to ineffective power consumption.
