Production And Quality
The testing item list and the checks run against each model's published parameter table.
How A Project Runs
The same route runs for a 3.2V cell pack and a 51.2V cabinet.
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.
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
Packed to the carton count agreed for your channel.
What Gets Checked
Our battery testing item list separates safety items from reliability items. Both are run against the parameter table published for the model.
- Capacity against the typical and minimum figures in the model's parameter table
- Nominal voltage and internal resistance where the data sheet publishes it
- Charge and discharge current against the standard and maximum figures
- Protection board function for over-charge, over-discharge, over-current and over-temperature
- Cell balancing across a completed series string
- Case, terminal, cable and connector against the customer drawing
- Label, logo and packing against the agreed carton count
Cells in one series string are supplied from the same batch, which is what keeps a string balanced over its life.
