Matters needing attention
★Take a 3000 mA battery for example, the 7S 1P battery holder full of batteries the capacity is 3ah, 7S 2P is 6ah. and you can stack the number of battery holders according to your actual needs.

★We've got three BMS for you, 20A /40A and 60A versions. The BMS have the functions of charge and discharge protection, discharge current protection, temperature protection, voltage equilibrium, and balance impulse. The 7S requires a 29.4v charger.
★Do not use it on metal table top, pay attention to insulation and do not short circuit.
★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).
★The direction of battery installation is subject to the mark on the cirucit board，not the mark on the plastic battery box.
★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 .

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, you need to increase the boost module. If the output voltage of the solar panel is too high, you need to increase the buck module. For specific questions, you can contact our store customer service.
