Sunder is an OEM and ODM manufacturer. Most of what we ship is a pack that did not exist before the customer's drawing arrived.
Step By Step
How It Runs
Requirement Analysis
Voltage, run time, peak current, ambient range, enclosure and connector. If the run time is still open we work back from the load and the hours you need.
Chemistry And Cell Selection
LiFePO4 where cycle life leads, lithium ion where energy density leads, lithium polymer where the space is a thin rectangle, Ni-MH where the product is locked to a 1.2V cell size.
Series And Parallel Design
The arrangement sets voltage and capacity. We publish it for every standard pack, for example IFR32700 4S17P for 12V 100Ah, so the comparison is transparent.
Protection And Balancing
Over-charge, over-discharge, over-current and over-temperature protection with internal cell balancing. Communication ports where the system needs them.
Sample And Test
After price confirmation you can request samples to test. Cells and packs are checked against the parameter table published for that model.
Case Wiring And Label
ABS or lead acid style case, aluminium case for e-bike packs, PVC wrap for modules, with your terminal, cable length, connector and logo.
Production And Packing
Built by our 500 worker factory, packed to the carton count agreed for your channel.

View data sheetQuestions About Custom Battery Pack Development
Can I get a sample before ordering?
After price confirmation, you can request our battery samples to test.
Do you put our logo on the pack?
Yes, custom logo is available on our packs.
What do you need from us to start?
Voltage, capacity or run time, peak current, the space available, the connector and the operating temperature range. A drawing or the current pack helps most.
