Frequently Asked Questions

Will these batteries work for my RV/Solar setup, even if I’m a beginner?

Yep! They’re designed to be easy to handle and install, whether you’re new to RVs and solar or already have some experience. Just match the voltage to your system, and you’re good to go. We’ve even seen first-timers set them up without stress!

I see different “BMS” ratings (like 100A). What does that actually mean for how I can use the battery?

Good question! The BMS (Battery Management System) protects the battery. A 100A BMS means the battery can handle up to 100 amps continuously. So, add up the amps of everything you plan to run at once – if it’s less than 100A, you’re set! Going over could trip the BMS and shut things down to protect the battery, which is obviously not what you want.

What’s the deal with “low-temperature cutoff” on some of these batteries? Is that really important?

It can be! LiFePO4 batteries don’t like charging when it’s freezing. The low-temperature cutoff stops charging if the battery gets too cold, preventing damage. If you camp or use your battery in cold places, it’s a feature you will want.

Some batteries say “automotive grade” cells. Is there a big difference between those and regular LiFePO4 cells?

There can be! “Automotive grade” usually means these cells meet standards for vibration, temperature swings, and overall durability like the Lossigy 12V 100Ah. They’re often built to last longer and handle tougher conditions, which you will love if you’re bouncing down bumpy roads or dealing with changing weather.

What’s the lifespan of these batteries? I see different cycle ratings – what should I expect?

The cycle rating tells you approximately how many times you can fully charge and discharge the battery before it starts to degrade. A battery with “4000+ cycles” should last for years with regular use. The LiTime 12V 100Ah TM boasts this feature! Keep in mind that depth of discharge (DOD) affects lifespan – shallower discharges generally mean more cycles.
