Quick Answer: Do you need a special charger for RV lithium batteries?

For smart or standard alternator charging, the lithium battery requires a DC-to-DC charger. Aside from isolating the truck battery from the camper house battery, the DC-DC charger provides the necessary 14.6 volts and charging profile required for LiFePO4 charging.

Do lithium RV batteries need a different charger?

No, your RV wiring system is designed to safely handle 45-Amps increasing it to a 60 or 80-Amp charger could cause a thermal event! When updating to a Lithium Battery System, stick with the same size Converter/Charger as presently installed in your RV!

Can you charge a lithium battery with a regular charger?

You can use a lead-acid charger to charge lithium batteries as long as you can set the maximum voltage of the charger and as long as the charger does not have an automatic equalisation mode enabled.

What type of battery charger do I need for a lithium battery?

The ideal way to charge a LiFePO4 battery is with a lithium iron phosphate battery charger, as it will be programmed with the appropriate voltage limits. Most lead-acid battery chargers will do the job just fine. AGM and GEL charge profiles typically fall within the voltage limits of a lithium iron phosphate battery.

What kind of battery charger do you need for a lithium battery?

Lithium batteries require a Constant current/Constant voltage (CC/CV) charge type with simple Bulk, Absorption, Float stages. Many lead acid chargers have desulphation and equalisation stages built in, which will pulse high voltages of 15.3-15.8V into the battery.

Can you charge a lithium battery with a 12 volt charger?

Please find below the answer why it shouldn’t be done. Simple answer: it is POSSIBLE, but you have to be VERY CAREFUL and you RISK your battery life. A 12v lithium LiFePO4 battery fully charged to 100% will hold voltage around 13.3-13.4v. Its lead acid cousin will be approx 12.6-12.7v.

What kind of charge does lithium have?

Periodic Trends of Lithium

In compounds lithium (like all the alkali metals) has a +1 charge.

Can my RV converter charge a lithium battery?

Lithium batteries require anywhere from 14.2V to 14.6V of constant charge voltage. This can be accomplished with a lithium specific charge converter, some sophisticated hybrid inverter/chargers often found in higher-end RVs, and as you’ll see via the manual override pendant on my PD9260 InteliPower charger.

Can lithium batteries be recharged?

Lithium batteries were invented before lithium-ion batteries. However, because they could not be safely or easily recharged, companies were motivated to come up with a rechargeable alternative. Enter lithium-ion batteries. These batteries can be recharged many times before they suffer degrading.

Do lithium batteries need a DC to DC charger?

Lithium batteries must be charged with the correct charging profile; a DC to DC battery charger is the only way to achieve this. Modern vehicles are now fitted with smart alternators that don’t produce a high enough voltage to charge auxiliary batteries.
