Customization Options
Sunder is an OEM and ODM manufacturer. The list below is what is decided by the customer rather than by us.
- Series and parallel arrangement to reach the voltage and capacity you need
- Case, terminal and cable length to match the equipment it replaces
- Connector fitted to your mating part
- Custom logo and label
- Dimensions made according to the device's request
What we need from you. Voltage, capacity or run time, peak current, the space
available, the connector on your board and the operating temperature range. A drawing or the pack you use now
answers most of these at once.
Use Guide
Charge with CC then CV
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.
Respect the charge floor
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.
Do not rely on the protection board
The board is a backstop against faults, not a charging strategy. Set the charger correctly first.
Store around 20℃
Store in the shipment state at roughly 20℃. The storage window per duration is published in the parameter table.
