Lithium batteries give you more usable power at less weight, but they need the right charging to last.
- Your charger, solar regulator and DC-DC charger all need a lithium charge profile.
- A DC-DC charger is the reliable way to charge from your tow vehicle while driving.
- Cable size matters. Undersized cable over the length of a car and van means lost charge and heat.
Have a 12V specialist check the whole system before you drop in a new battery. It’s cheaper than replacing one early.
