Warm Tips:(Battery not included)
1.The 7S requires a 29.4v charger.
2.Do not use it on metal table top, pay attention to insulation and do not short circuit.
3.The charging current of each layer is not recommended to exceed 2a, otherwise the battery may generate heat (for example, if there is only one layer, choose 2a charger, and if there are two layers, choose 4a charger).
4.Look at the circuit board with the battery orientation,and all the batteries cannot be staggered in the same orientation.
5.Don't connect the power supply with the wrong positive and negative, there are signs on the circuit board, pay attention to observation.
