Product Q&A

Ask Us a Question
  • Will this charger charge without the ignition wire attached or is it voltage sensing Like most other chargers?

    Hi There,

    The charger requires the ignition wire to be connected for it to charge.

  • Hi Guys I have a agm 180 amp battery behind the back seat , iv added a canopy which I want to put this unit into . Can I plug a Anderson plug from the agm battery to the lithium input to charge the lithium? Cheers Steve

    Hi There,

    To charge this lithium battery you would need to connect up the DC DC charger from this kit.

    The DC DC charger has a built in lithium charging profile that is designed to charge the lithium battery safely, and correctly.

    We would not recommend trying to connect an Anderson plug from a second battery, directly to the lithium battery.
