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

  1. Charge with CC then CV

    Charge at 0.2C constant current to 4.2V, then hold that voltage until the current tails off.

  2. Do not over-discharge

    Stop at the published cut-off voltage. Repeated deep discharge is what shortens a lithium ion pack fastest.

  3. Keep it cool

    Charge between 0℃ and 45℃. Heat, not cycles, ends most tool packs.

  4. Store part charged

    Store around 20℃ in the shipment state rather than fully charged or flat.
