Precautions

Please purchase at least one BMS. We did not connect the negative output of the "3S without BMS" (including 3S 4P) XT60 plug in the design, we need to use the front copper socket and the cable to connect the 3S BMS for output. BMS can provide charge and discharge equalization while providing functions for the whole system (multiple battery holders).

Taking a 3000mA battery as an example, the battery capacity of a 3S 1P battery holder is 3ah, that of a 3S 2P is 6ah, and that of a 3S 4P is 12ah. You can stack the number of battery holders according to your actual needs.

3S charging requires a 12.6V charger.

It is recommended that the charging current of each layer should not exceed 2A, otherwise the battery may heat up (for example, choose a 2A charger for only one layer, and a 4A charger for two layers).

Do not use it on a metal table, pay attention to insulation and do not short circuit.

Batteries face the board, all batteries facing the same side cannot be staggered. The direction of battery installation is based on the mark on the circuit board, not the mark on the plastic battery case.

Do not wrongly connect the power supply, there are marks on the circuit board, pay attention to observe.

The list price is the price of the circuit board or battery box.

If you use a solar panel to charge the battery, you need to bring your own voltage control module. If the output voltage of the solar panel is too low, a booster module needs to be added. If the output voltage of the solar panel is too high, a step-down module needs to be added. For specific questions, please contact our customer service.
