What should you know when comparing LiFePO4 batteries?

It’s important to remember a few things when comparing LiFePO4 batteries. These include the Battery Management System (BMS), cell grade, and how long they last. A reliable lithium battery is peace of mind (and then some).

What is a LiFePO4 battery?

Short for lithium iron phosphate, LiFePO4 batteries use LiFePO4 as a cathode, with a metal-backed graphite carbon anode. These batteries have a much higher specific capacity than other batteries. In plain English, this means you can get significantly more juice from a battery that’s lighter than other varieties.

Are LiFePO4 batteries safe?

LiFePO4 batteries also have a set-up and chemistry that makes them safer than earlier-generation lithium-ion batteries. These features make LiFePO4 batteries less likely to overheat, and they don’t give off toxic fumes like many traditional batteries do.

Is renogy LiFePO4 a good battery?

Renogy’s LiFePO4 battery is rated for over 4,000 charge and discharge cycles. This is unheard of with other types of batteries, and allows for years or even decades before needing a replacement. It puts out 100 amps of continuous current, and charges at a brisk rate of 50 amps. However, there’s no listed rating for surge output.

Can you use a LiFePO4 battery on an RV?

Most lithium battery manufactures recommend only using lithium specific chargers, the only exception to this is Battle Borne, they advertise their premium RV lithium battery to be 3-stage smart charger compatible, which most RVs today use. Check the charge cycle life rating. Higher-quality LiFePO4 batteries often offer 3000-5000 cycles or more.

How much does a lipofe4 battery cost?

Keep in mind that you likely have to change your controller ($300) and add a DC DC charger ($300) in between to protect your alternator. I have a $400 100Ah LiPoFe4 and can't complain so far. They’re about 30 cents a watt hour now to put together your own 12v batteries (from four 3 volt cells). You’re talking about 1200 watt hours.
