I am reviewing the BattleBorn 100 AH Lithium iron battery LiFePO4. First a bit about myself, I have lived 100% off grid since December 2007, we built our small solar system ourselves using solar panels and have used various deep cycle batteries over the years. The batteries were always the part of the system that wore out needing to be replaced. Even though our system was small, it still cost in the neighborhood of $400+ for a very minimal amount of batteries. This time we decided to bite the bullet and go with the Lithium iron phosphate LiFePO4 battery.
Yes, it is expensive up front, but once I factored in the lifespan (10-20+ years!), the fact that you get the FULL amount of the battery discharge (with lead acid batteries, you should only ever use the top 20-50%, any more than that lowers the life of the battery, the deeper you discharge, the quicker those batteries will die-ie not hold a charge), no maintenance, lightweight (30ish pounds for the BattleBorn 100 AH battery), I decided that this was the best bang for my buck.
I researched the major LiFePO4 battery manufacturers and BattleBorn kept coming up on top every time. What ultimately sold me on them is you can connect their batteries in parallel (as well as series), the other major manufacturers of LiFePO4 batteries said you couldn't connect their batteries in parallel (as of the time of my purchase, this fact may change in the future for the other manufacturers), but BattleBorn does allow for that. I only have 1 battery at the moment, but will soon buy a second one to add to my system, hooking up in parallel to make a 12 volt 200 amp hour system.
The other thing that sold me on this company is they offer a 10 year warranty on their batteries, as of now no other manufacturer has this length of warranty.
I ordered my battery through Amazon, you can also order directly from BattleBorn. Shipping is free through either site. I have been using this battery about a month now, I am amazed at how quickly it charges up, and unlike my previous golf cart lead acid deep cycle batteries, I don't have to worry about how far I'm discharging the battery.
Bottom line, it's worth every penny!
