7.4V 6.4Ah 18650 Battery Pack — 2S2P Industrial
| Configuration | 2S2P |
| Cell | Panasonic 18650BD |
| Nominal voltage | 7.4V |
| Capacity | 6.4Ah typical / 6.2Ah minimum |
| Charge ending voltage | 8.4V |
Overview
The 2S2P configuration pairs four Panasonic 18650BD cells for a 7.4V, 6.4Ah pack with battery management, lead wire and connector, aimed at industrial and portable equipment. The fitted board provides battery management with short-circuit protection; charge ends at 8.4V and discharge at 5.0V per the specification.

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 2S2P configuration of this pack?
2S2P means two cells in series and two in parallel: the series pair sets the 7.4V class voltage and the parallel pair brings capacity to 6.4Ah typical from the Panasonic 18650BD cells.
What protection board is fitted?
The pack is fitted with a battery management board providing short-circuit protection, with an 8.4V charge ending voltage and a 5.0V discharge ending voltage.
Can a 7.4V pack be built at a lower capacity, around 2200mAh?
Yes. The 2S platform is built in several capacities by changing the parallel count and the cell fitted, so a lower-capacity 7.4V rechargeable pack — including builds around the 2200mAh class — follows the same configuration logic as this model. Tell us the capacity and discharge current your device needs, and we will confirm the configuration and cell that fit.
