Note:
1. The upper and lower layers can be superimposed, only increasing the capacity without changing the voltage.
Taking 3000 mAh per battery as an example, a full battery on a 4S1P circuit board is 15V 3A, 4S2P is 15V 6A, and 4S4P is 15V 12A. You can stack battery boxes arbitrarily according to your actual needs.
2. During the battery charging or discharging process, the voltage will change, and the product's protection board does not have the function of output voltage stabilization.
3. Lithium battery must be pressure measured in advance and the internal resistance paired.
4. Positive and negative can not be reversed.
5. Support multi-layer battery board with cable connection. (But does not include cable, you need to purchase separately)
