1: The aluminum substrate has super heat dissipation and higher safety. Even if an accident occurs, there be no open flame. 2: Large integrated inductor, stable performance. Active balance, energy fer. 3: Three times of active protection, steady voltage and steady flow. 4: Lithium battery equalization 3-24 series battery automatic equalization pressure difference repair, with indicator light. 5: Send high-quality bold silicone flexible cable 30CM.<br><br>Special emphasis: large inductance active equalization board 1. The active balance board cannot replace the protection board. 2. The active equalization board cannot be used for daily debugging. It can only be used together with the protective plate and fixed in a box. Note: It is forbidden to directly solder the battery with the balance board. You need to remove the cable first, connect the battery pack according to sequence, and then connect the cable interface to the balance board after confirming that it is correct, otherwise the balance board be burned. Know Before You Buy: 1. This product is mainly used for ternary lithium and lithium iron phosphate battery packs to balance the voltage of each string of batteries. 2. Before buying, please check whether the battery pack has poor battery life due to excessive pressure difference. If the battery is , the internal resistance is too large, starvation, water ingress, etc., it cannot be repaired. 3. The active equalization board automatically turn on the balance when the adjacent voltage difference exceeds 0.1V, no external power supply is required, please check whether the battery voltage difference is higher than 0.1V before purchasing. Due to different product batches, the appearance , which does not affect the use.
