25.2V 9Ah custom NCM lithium battery pack with approximately 226.8Wh nominal energy in a 7S2P configuration. The PVC-wrapped pack has red and black 14AWG power leads and a protection circuit with overcharge, over-discharge and temperature protection plus cell balancing. Its 10-20A discharge range is limited to no more than 5 minutes.
Model JG-7INR25.2-9-Y (specification S2.0119-N2-0702-25-001) uses 26650 NCM lithium-ion cells in a 7S2P arrangement. The PVC-wrapped pack measures 125 ± 2 × 147 ± 2 × 53 ± 2mm and weighs 1.5 ± 0.1kg. Check the device operating voltage, load profile, installation space and charger before selection.

Evaluate this pack for compatible OEM equipment requiring a 25.2V nominal supply. Verify the full voltage range, continuous and peak current, peak duration, enclosure size, lead termination and charger. Use a 29.3-29.4V lithium-ion charger with no more than 4A charge current. Provide ventilation if the pack operates in ambient temperatures above 45°C, as the manual directs.
No. The manual specifies up to 10A discharge and lists the 10-20A range for no more than 5 minutes. Submit the full load profile for design review.
The manual specifies 14AWG red and black power leads measuring 200 ± 15mm; it does not specify a termination connector. Confirm the required connector and polarity.
Compatibility depends on the equipment's voltage range, current demand, charger, protection requirements, dimensions and wiring. Nominal voltage alone is insufficient to establish fit.
Contact Surlon Power and reference S2.0119-N2-0702-25-001 to discuss samples or a custom configuration.
