Matters needing attention

★★★★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, it needs to use the front copper socket and ribbon cable to connect 3S BMS for output.BMS can provide charge and discharge equalization function for the entire system (multiple battery holders) at the same time.

★Take a 3000 mA battery for example, the 3S 1P battery holder full of batteries the capacity is 3ah, 3S 2P is 6ah, 3S 4P is 12ah. and you can stack the number of battery holders according to your actual needs.

★3S charge needs 12.6V charger.

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

★Do not put on the metal table top to use, pay attention to insulation do not short circuit.

★The battery faces up the circuit board, all the batteries face the same cannot interleave.The direction of battery installation is subject to the mark on the cirucit board，not the mark on the plastic battery box.

★Do not connect the wrong power supply, the circuit board is marked, pay attention to the observation.
