Kastar M53615 USB Dual Battery Charger

The Kastar M53615 is a dual-slot charger designed for Motorola Talkabout two-way radio batteries. It accepts Micro-USB or USB Type-C input at 5V 2-3A and can charge two compatible Li-Ion packs simultaneously at 8.4V or 4.2V with an 800mA current per slot. An integrated LCD panel shows real-time charging status and remaining capacity for each bay. The unit ships with a Micro-USB cable and measures five by three by one inches.

For Talkabout owners needing multi-bay charging

Radio users who carry spare packs for models such as the T480, T600 H20 or T800 can replenish two batteries at once from any standard USB power source. The charger supports a long list of Motorola battery part numbers including 53615, PMNN4477 and HKNN4002 series. Buyers who need to charge three or more packs at the same time, or who require a dedicated AC wall adapter instead of USB power, should look at a different solution.

Dual simultaneous charging at 800mA per slot

The defining specification is the ability to charge two batteries concurrently at 800mA each from a single 5V USB input. This throughput determines how quickly depleted Talkabout packs return to full capacity and whether the charger keeps pace with heavy daily use. If your operation demands faster per-bay current or more than two simultaneous channels, this model will not meet that requirement.

Questions about this item

Will the LCD panel or USB ports need replacement after heavy use?

The unit has no user-serviceable parts; the LCD and Micro-USB or Type-C inputs are built into the charger body and are not designed to be swapped.

What stops the charger from running continuously at the 800 mA single-bay rate?

The intelligent charging circuit monitors each cell and automatically reduces current once the battery reaches 8.4 V or 4.2 V, preventing sustained maximum output.

Does the charger get hot or draw more than the 5 V 2-3 A input when both bays run all day?

With a 5 V 2-3 A supply the total draw stays within that range; the enclosure is passively cooled and runs warm but not hot during dual-bay operation.
