Applications
Where this voltage platform is used
The 7.4 V platform matches consumer electronics and low-power handheld devices: moderate capacity and a compact footprint that fits the tight space inside an earbud case, beauty device or small appliance. These products prioritise low weight and easy charging, so we tailor the form factor and structure to your mounting space and interface.

FAQ
Common questions about 7.4V battery packs
How is the capacity of a 7.4 V pack determined?
It follows from your device power draw and target run time. Provide the standby current, operating current and expected service time, and we assess a capacity direction confirmed against the actual model, without a preset ceiling.
Can the form factor match our battery bay?
Yes. Provide the three-dimensional limits of the bay and the interface requirements, and we design the structure in the pouch or cylindrical direction, fitting your mounting space as closely as capacity and discharge requirements allow. Samples follow the same technical and inspection standards as production.
What documents are needed to export a 7.4 V pack?
On certification, CE / IEC 62133 / UL 2054 / RoHS / REACH have been passed, and the applicable items are confirmed per your target market and model. Export transport documents are confirmed per model, with the specific items set by your order and target market.
