18650 Lithium Battery Holder 7S Power Bank Box Balance Bluetooth 20A 40A 60A

Updated power wall system comes with its own protective board, which saves costs and reduces the difficulty of use.
It is very practical.

Matters needing attention

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.
6. Product single circuit board option, excluding the battery in the photo.
7. The list price is the price of a circuit board or a battery

Due to the misunderstanding of this product, it is specifically stated that the order is known as follows:

1. The battery direction of all battery cases is subject to the PCB board.
2. The product is only a circuit board, does not contain a battery, battery box and BMS are purchased separately
3. If used as a multi-layer battery station, select a piece with a protective plate, and the remaining options do not have a protection plate. The protection plate can provide a balance equalization function for the entire multi-layer battery case, without having to add a protection plate to each layer.
