VoltFlow 9-Stage Smart Battery Charger 12/24V 20/10A

A flat battery always picks the worst morning. This VoltFlow smart charger is the set-and-forget fix, with 20 amps on tap for 12 volt batteries and 10 amps for 24 volt, so it handles the car, the ride-on, the truck, the caravan and the boat.

It reads the battery itself and runs a 9-stage charge, starting gentle, bulking up, then dropping back to a float that keeps things topped up without cooking the battery. It works across lead acid, AGM, gel, deep cycle and lithium including LiFePO4, and a repair mode helps bring tired, sulfated batteries back to life. Pick 5, 10 or 20 amps to suit the battery you are charging.

A built-in fan keeps it cool and temperature compensation stops it overworking on a hot day. Leave it connected over winter and your weekend toys fire up first turn. The full charging detail and battery types are listed in the tabs below.
