Data sheet published by Sunder Battery for this model.
The 32700 LiFePO4 cell 6000mAh is one line of the range below. Compare the capacity, dimension and maximum discharge current before deciding, because a pack sized on capacity alone is often the wrong pack.

Table published by Sunder Battery for this product family.
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 3.65V.
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 3.2V and typical capacity 6000mAh. The full parameter table is published on this page.
The LiFePO4 Cell range is published at more than 2000 cycles with 80% capacity remaining at 100% DOD.
3.65V, charged constant current then constant voltage. The normal charge current is 0.2C to 0.5C and the maximum is 1C.
Approximately 145g. 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.
