Build and options
Leads, connectors and labelling are confirmed against your equipment drawing before samples are made, and the pack is built to the specification above once it is confirmed. For shipping and compliance files, UN38.3, IEC 62133 and MSDS documents can be confirmed and provided for specific models — tell us the model you are buying and we will confirm which documents cover it.
Frequently Asked Questions
What is the 3S2P configuration of this pack?
3S2P means three cells in series and two in parallel: the series string sets the 11.1V nominal voltage and the parallel pair doubles the 2600mAh-class cell capacity to 5.2Ah typical.
Which industrial devices is it built for?
The documented application fields are e-bikes, robots, UPS units, automated guided vehicles, medical equipment, power tools and lighting.
