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 0.2C constant current to 12.6V, then hold that voltage until the current tails off.
Do not over-discharge
Stop at the published cut-off voltage. Repeated deep discharge is what shortens a lithium ion pack fastest.
Keep it cool
Charge between 0℃ and 45℃. Heat, not cycles, ends most tool packs.
Store part charged
Store around 20℃ in the shipment state rather than fully charged or flat.
