Data sheet published by Sunder Battery for this model.
Power battery, long life, safety durable, over voltage protection, over-current protection, over-charge protection, over-discharge protection, short circuit protection, temperature protection.
Sunder is an OEM and ODM manufacturer. The list below is what is decided by the customer rather than by us.
Charge at constant current, normally 0.2C to 0.5C, until the cell reaches 3.65V, then hold that voltage until the current tails off. At pack level that is 54V / 58V.
Charge between 0℃ and 45℃. Charging a frozen pack is the most common way an outdoor battery is damaged, and it is a controller setting.
The board is a backstop against faults, not a charging strategy. Set the charger correctly first.
Store in the shipment state at roughly 20℃. The storage window per duration is published in the parameter table.
Nominal voltage 51.2V and typical capacity 50Ah. The full parameter table is published on this page.
The LiFePO4 Battery Packs range is published at more than 2000 cycles with 80% capacity remaining at 100% DOD.
54V / 58V, charged constant current then constant voltage. The normal charge current is 0.2C to 0.5C and the maximum is 1C.
Approximately 31.5KG. The dimension and weight for every model in the range are in the model list on this page.
Yes. The charge and discharge current can be customised and the dimension is made according to the device's request. Custom logo is available.
After price confirmation, you can request our battery samples to test.
