Matters needing attention

★★★★Please purchase at least one BMS. BMS can provide charge and discharge equalization function for the entire system (multiple battery holders) at the same time. The BMS have the functions of charge and discharge protection, discharge current protection, temperature protection, voltage equilibrium, and balance impulse.

★ It is better to place the order together with the BMS to avoid over-charging and over-discharging and unbalanced voltage in the process of use.

★It is better to choose our dedicated charger. If there are other chargers, you need to choose DC 5.5X2.1 mm socket.

★The charger needs to choose 42v charger. It is recommended that the charging current of each layer shall not exceed 1A.

★Direction for use

1.Check whether the product is in good condition before use.

2.Put it in the battery and use it when fully charged

★Don't connect the power supply with the wrong positive and negative, there are signs on the circuit board, pay attention to observation.

★Product single circuit board option, excluding the battery in the photo.

★The list price is the price of a circuit board or a battery holder.

★The direction of battery installation is subject to the mark on the cirucit board，not the mark on the plastic battery box.

Take a 3000 mA battery for example, a battery holder full of batteries is 3ah, and you can stack the number of battery holders according to your actual needs.
