  • 15C discharge rate delivers strong power bursts

Two-pack 7.4 V 1500 mAh Li-ion with SM-2P plug

This twin-pack supplies two 7.4 V 1500 mAh lithium-ion cells built with a 2S configuration and a 15C discharge rating. Each cell measures 70 by 37 by 19 mm and weighs 95 g. The SM-2P connector has a cross-section of 5.6 by 4.9 mm. A USB charge cable with a JST-XH 3-pin plug is included; it accepts 5 V input and delivers 7.4 V at 1000 mA.

For owners of legacy H101 H103 H105 RC boats or cars

The pack suits hobbyists running older TKKJ Skytech H101 H103 H105 models that still use the black SM-2P connector. Builders whose vehicles have moved to a different plug or who need a higher capacity than 1500 mAh should look elsewhere. The bundled USB charger is limited to 1 A output, so users wanting faster parallel charging will need separate equipment.

SM-2P connector geometry decides fit

The critical spec is the SM-2P plug with its 5.6 by 4.9 mm cross-section; if the original battery does not match this exact connector and the 70 by 37 by 19 mm footprint the cells will not connect or sit in the tray. Always verify the plug and dimensions before ordering.

Questions about this item

Will the SM-2P plug on this 7.4V 1500mAh pack fit the original battery compartment of my older H101 boat?

The pack uses a black SM-2P two-pin connector with a 5.6 by 4.9 mm cross-section; verify your original battery shows the same plug shape and dimensions before installing.

How can I confirm the USB charger is delivering a proper charge to the 2S Li-ion cells?

The charger cable accepts 5 V DC input and outputs 7.4 V at 1000 mA with an integrated IC circuit; a steady indicator light on the cable typically shows charging is active.

What comes in the twin-pack box and is any extra lead required to start charging?

Two 7.4 V 1500 mAh batteries with SM-2P plugs and one USB charging cable with a JST-XH three-pin connector are included; no additional cable is needed to begin charging.
