7.2V 10.4Ah custom NCM lithium battery pack with 74.88Wh nominal energy and a 2S4P configuration. The compact PVC-wrapped pack includes overcharge, over-discharge and temperature protection with cell balancing, a DC5.5 × 2.1 charging connector and a JST SYR-02T1 discharge connector. Specified discharge current is 0.5A; higher current up to 3A is time-limited to no more than 5 minutes.
This custom NCM lithium battery pack provides 74.88Wh nominal energy in an 18NC-2S4P configuration. Its compact PVC-wrapped format measures 76 ± 2 × 75 ± 2 × 38 ± 2 mm and weighs 400 ± 30 g, making it a candidate for compatible equipment with a defined low-current load and limited battery space.
Model JG-2INR7.2-10.4-Y, specification S2.0119-N1-0204-04-001, uses separate charging and discharge connectors. Its protection circuit includes overcharge, over-discharge and temperature protection, together with cell balancing.

Evaluate this pack for low-current instrumentation, monitoring equipment, sensors and other compatible electronic systems. Select the battery against the equipment voltage range, steady-state current, peak duration, required runtime and available space. The 10.4Ah capacity does not imply suitability for high-current motors or other heavy loads.
Use a lithium-ion charger compatible with 8.3-8.4V and a maximum current of 3A. Verify polarity and connector pinout before connecting the charger or load. Built-in protection does not replace correct charger selection, system protection or thermal management. Do not connect packs in series or parallel. Keep the pack away from short circuits, water, fire and mechanical damage, and have qualified personnel perform installation and maintenance.
No. Maximum charging current is 3A, but specified discharge current is 0.5A. The manual separately lists 0.5-3A discharge for no more than 5 minutes. Confirm the complete load profile and duty cycle with the technical team before use.
The charging lead uses a DC5.5 × 2.1 plug, and the discharge lead uses a JST SYR-02T1 plug. Each lead is 125 ± 10 mm long. Confirm connector orientation and polarity during design review.
Only after checking the operating voltage limits, current demand, charger, enclosure dimensions, connector wiring and protection requirements. Matching nominal voltage alone is not enough.
Send the device voltage range, continuous and peak current, peak duration, target runtime, space drawing, connector details and charging requirements. Any requested changes are subject to technical review and an agreed specification.
