This lithium battery protection board provides continuous discharge of 30A, balanced current for various applications like electric drill, sprayer, LED lights, and low power inverter. It is suitable for a nominal voltage of 3.6V, 3.7V lithium batteries including 18650, 26650, and polymer lithium batteries. The board operates smoothly with a continuous charge current of 20A and is suitable for starting current below 80A, power 135W below the drill (with balance).
The board comes in a compact size of approximately 46 x 60 x 3.4 mm, making it easy to install on a battery bundle or in a small space. Please note that successful drill start requires specific power batteries and proper wiring according to the provided map.
When using the brush motor load, it is recommended to connect a non-polar capacitor to prevent reverse spikes from damaging the MOS tube. Ensure that the voltage of each group of batteries in series is the same to avoid issues during discharge tests.
