This product id a "DIY" build on demand item. It represents the paring of a power wheel designed to fit Black&Decker 20V lithium ion battery packs, with the internals of the "Croc" KX3 Battery Pack, found elsewhere on this site.
The Black&Decker 20V Lithium battery packs have the same 5S (5 cells in series ) configuration as the mediadogg Software "Croc" and "ninja" KX3 battery packs. Hence, the power regulation circuitry works perfectly with the ready-made power packs, originally designed to for power tools.
The resulting KX3 power packs is designed to safely deliver up to 45W at 3A , specifically for the Elecraft KX3 transceiver. It has internal RFI shielding and a built-in trickle charging port. Hence, the power tool battery pack can be safely charged, at a slow rate, using a standard 21V @1A lithium ion charger AC adapter in addition to the Black&Decker chargers, which are designed for safe charging at a faster rate.
Using the Trickle Charge Port
- Under no circumstances should anything be plugged in other than a specified Lithium Ion Charger for 5S configuration, maximum voltage 21.3V, maximum amperage 1A.
- A specified charger has circuitry that regulates voltage, current and time of charge.
- Monitor the battery pack and voltage meters frequently while charging. When the pack reaches 21V, the charger should be disconnected. A specified charger will also stop charging at this point.
(Note: a suitable AC wall charger is available that has been tested with the KX3 power wheel accessory.)
