Yes, with the Dark Speed "On The Run" charger. While your outboard runs, it uses the alternator to charge your 12V cranking battery first. It then sends extra power to your 24V or 36V trolling motor battery. That can add hours to your day without shore power or a generator. It comes in 12V/24V (DS24) and 12V/36V (DS36) models.

Yes, the batteries can be charged using solar panels. Please make sure your charge controller is compatible with lithium.

No, when you have three 12V batteries in series, they must be charged individually with a 12V charger. Attempting to charge the entire 44.1V series configuration with a single 44.1V charger is not recommended. Each battery needs to be charged separately.

Yes, you can discharge the battery down to 0%. When it reaches 0%, it will enter low voltage protection (sleep mode). To recharge, simply connect a lithium-approved charger, which will wake up the battery and begin charging it again.

Many RVers do, especially when the new battery drops into the same Group 24 or Group 31 box. Turn off shore power, solar and the battery disconnect first. Connect with ring terminals on the M8 terminals and tighten them to 10 ft-lb. Then check that your converter, solar controller and any DC-to-DC charger are set for lithium (see question 41). If you’re not comfortable with 12V wiring, have your RV service center do it, or call our Support Team at 855-MAX-LITH before you start.

Yes, you can jump start a lithium battery using an AGM or lead battery, as long as the jump starting battery has a higher voltage than the lithium battery you’re trying to start.

Yes, you can jump start a lithium battery. Use either another battery that is charged at least 50% or an approved lithium jump starter pack. We recommend jump pack for reliability.

Yes. A solar panel can stay connected to keep your Millertech battery topped off while your RV is parked. Set your solar charge controller to its lithium setting, or use a user-programmable setting set up for lithium. Turn off or disconnect everything else, so detectors and other small loads can't slowly drain the battery. Not sure how to set your controller? Call our Support Team at 855-MAX-LITH.

It’s built for the woods. The power cord is stainless steel, so squirrels and other chewers can’t get through it. Anti-theft cable slots let you lock the battery to the tree with your camera’s security cable.

Yes, in the same RV, but not in the same system. Never connect lithium and lead-acid batteries in parallel with each other, and avoid connecting them in series except in an emergency. Each type can still help the other in a pinch: a lead-acid battery can jump-start a dead lithium battery, and a lithium battery can jump-start a dead lead-acid battery.

Yes, on the same boat, but not in the same system. Never connect lithium and lead-acid batteries in parallel with each other. Avoid connecting them in series, too, except in an emergency. Each type can still help the other in a pinch: a lead-acid battery can jump-start a dead lithium battery, and a lithium battery can jump-start a dead lead-acid battery.

Yes. The Millertech app tracks up to six batteries at once, so there’s no switching between apps
