Product Name
3S/4S/5S/6S/7S/8S 200A High Current Lithium Battery Protection
Board
Intelligent Guardian, Source of Safe Power
Core Selling Point
1. High Current Carrying Capacity: Supports 200A continuous
discharge current, with a peak value of up to 300A (specific
parameters need to be adjusted according to the actual design),
meeting the high power requirements of power tools, energy storage
systems, etc.
2. Multiple String Compatibility: Flexible adaptation to 3S-8S
lithium battery packs(ternary lithium/lithium iron
phosphate/lithium titanate/sodium ion lithium batteries optional),
one board for multiple uses, reducing costs.
3. Multiple Protection Mechanisms: Five-fold protection for
overcharge, over-discharge, overcurrent, short circuit, and
temperature protection, fully guaranteeing battery life and safety
of use.
4. Industrial Grade Durability: Adopting imported MOSFET + low
internal resistance PCB design, efficient heat dissipation, and
stability far exceeding similar products.
5. Intelligent Monitoring: It can be customized for Optional
Bluetooth/Wi-Fi module (if supported), real-time monitoring of
battery voltage, temperature, and power, making remote management
more convenient.

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!
