USB charging cable for 7.2V RC packs

This cable lets you charge 7.2V 250mA Ni-MH or Ni-CD batteries from any standard USB port. It is aimed at RC car owners who want a compact way to top up packs without a dedicated mains charger. The EL-2P plug mates directly with the battery connector. An IC protection circuit guards against overload and overvoltage. A red indicator shows the charging state at a glance.

Thermal and power behaviour in normal use

Power is drawn from a 5V USB source and converted to the 7.2V output required by the pack. The 250mA charge current keeps heat generation low during typical charging sessions. No active cooling is needed and the cable runs silently. The built-in protection circuits prevent excessive current or voltage from reaching the battery.

Behaviour under sustained load

During a full charge cycle the cable maintains the regulated 250mA output until the pack reaches capacity. The IC protection continues to monitor for overload or overvoltage throughout the extended session. Temperature rise remains modest because the charge rate is limited by design. The red indicator stays lit while charging and changes or extinguishes when the cycle completes.

Questions about this item

How do I plug the EL-2P connector onto my 7.2V pack without reversing the polarity?

Match the battery port's red lead to the charger port's white lead for positive, and the battery port's black lead to the charger port's black lead for negative; the reverse wiring is intentional for this cable.

Will the USB charger cable itself wear out and need replacement over time?

The cable has no user-serviceable parts; if the USB plug, EL-2P connector or internal IC protection circuit fails, the whole cable must be replaced.

What limits the charge rate during a long session from a standard USB port?

The cable is fixed at 250mA output, so a standard 5V USB port will never push more current than that regardless of session length.
