Flashpoint Multi Battery Charger for the XPLOR 600, 600Pro, and 400 Pro recharges the replaceable Lithium battery packs, independently and all together in designation order. The charger is smart! Even though each one of the XPLOR models has cells with aspecific voltage and unique specs, they are automatically sensed by the Multi Charger to properly refresh at the right rate and protect the cells from overcharging. Up to three different packs plug in the matching port socket. The charger LCD monitors the progress separately and displays the level and user priority sequence. The Multi Battery Charger system can be powered by the included DC power supply or run off of USB-C sources as well.
