Vexilar's MAX Lithium Battery delivers 12 volts and 12 amps of power, the most in its class to be a drop-in replacement for existing 12-volt SLA batteries with half the weight. When combined with the Vexilar 2.5 Amp Hour Rapid Charger, it is an unbeatable combination. Vexilar has put these two great products together to create the V-220L Combo Pack. It even comes with a set of gator clips to easily attach to the battery terminals, or directly using the Vexilar Quick Connect charging system.
