Ni-MH cells and packs remain the practical choice for appliances designed around 1.2V cells and for the service channel that keeps installed equipment running.
Industry Pain Points
What Goes Wrong Today
- A product family designed years ago around a cell size that cannot change
- Service demand that outlives the original pack supplier
- Retail packs of unknown capacity that fail early
Customer Needs
What Buyers Ask For
- A capacity ladder in one pack size, so one tool serves several SKUs
- Packing that suits retail and service channels
- Cells with published dimension and weight for the housing check

How A Project Runs
The same route for every industry, from the first drawing to the packed carton.
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.

Questions About Home Appliances Batteries
Which robot vacuum packs do you make?
14.4V Ni-MH SC type packs at 3000mAh, 3300mAh, 3500mAh, 3800mAh and 4000mAh for the Roomba 500 series, packed one piece per inner box and ten per carton.
Can you build appliance packs in other voltages?
Yes. Ni-MH cells from AAA to D are assembled into series and parallel arrangements to order, as with the 12V 10S1P AA2000mAh pack.
Do you supply cells for our own assembly?
Yes, the full AAA, AA, C, D and SC range is available as bare cells.
