7.2V 5Ah custom NCM lithium battery pack with approximately 36Wh nominal energy in a 26NC-2S1P configuration. Its cylindrical PVC-wrapped body is Ø27 ± 1 × 135 ± 3 mm. A JST-XH-3P lead provides positive, negative and 100K NTC connections. Specified discharge current is up to 0.1A; 0.1–1A is limited to no more than 5 minutes.
This custom NCM lithium-ion pack provides approximately 36Wh in a 26NC-2S1P configuration. Its cylindrical PVC-wrapped body measures Ø27 ± 1 × 135 ± 3 mm and weighs 190 ± 20 g. A JST-XH-3P lead combines charge/discharge wiring with a yellow NTC sensor wire.
Model JG-2INR7.2-5-Y is distinct from other 7.2V 5Ah packs by its 26NC-2S1P configuration, cylindrical dimensions and JST-XH-3P lead. Confirm the complete electrical and mechanical fit before substitution.

Evaluate this pack for equipment whose continuous current stays within the specified 0.1A limit. The 1A discharge figure applies only for no more than 5 minutes. Verify JST-XH-3P pinout and polarity before connection. The yellow wire is an NTC signal; configure suitable system temperature monitoring and protection. The manual specifies charging at 5–45°C and discharging at −20–55°C, and calls for charge protection temperature no higher than 55°C and discharge protection temperature no higher than 60°C. Use a charger meeting the specified voltage and current limits.
No. This model is JG-2INR7.2-5-Y, specification S2.0568-N2-0201-05-001, with a 26NC-2S1P cylindrical construction and JST-XH-3P/NTC lead. Check dimensions and wiring before choosing a replacement.
The specification lists an NTC lead and overcharge, over-discharge and balancing functions. It does not state that the protection circuit provides an internal temperature cut-off. Design the host system’s temperature monitoring and protection to the stated limits.
No. The specified discharge current is up to 0.1A. The 0.1–1A range is limited to no more than 5 minutes.
