The EarthX Lithium batteries (LiFePO4) are designed to be a light-weight, maintenance free replacement of your standard lead-acid battery.
These batteries will work with any vehicle charging system and "modern" lead-acid battery chargers, thanks to the exclusive built-in electronics (Battery Management System, BMS).
No other motorsport lithium battery manufacturer offers a battery with built-in electronics to protect it from over-discharging, over-charging, plus keep the cell's charge level balanced.

The EarthX ETX680C was my choice for an aircraft application, but when I took the battery from the shipping box and rotated it in my hands, it went "thud" within it's own case. Something substantial was free to move inside the battery case, not withstanding the fact that the terminal voltage tested normal full charge. I contacted EarthX via their email portal and got a response within 30 minutes !! They shipped a replacement the same day. The new battery, without a "thud", was in my hands 2 days later, along with a prepaid return shipping label for the "thud" unit.
Customer service doesn't get any better than that.
I HAD ANOTHER (BRAND) LITHIUM BATTERY FOR 6 YEARS TIL IT DIED BUT IT NEVER TURNED THE ROTAX912S LIKE THIS EARTHX 680C DOES. LOOKS LIKE A GREAT BATTERY AND ESPECIALLY THE FACT THAT IT HAS AN INDICATOR LIGHT THAT GIVE ONE AN INDICATION OF BATTERY TROUBLE. I MOUNTED THE INDICATOR LIGHT IN A SPOT THAT I WILL NOT MISS IT IF SOMETHING DOES GO WRONG. I DON'T EXPECT A PROBLEM BUT IT'S NICE TO HAVE A BACK UP SYSTEM. TELL YOU HAW THINGS GO IN 8 YEARS WHICH IS THE POSSIBLE LIFE OF THE BATTERY.
I purchased the Earth X battery to replace 2 Odyssey batteries I had for my Lycoming O320. The battery arrived in very secure and padded box with in 7 days of order. The battery is extremely light and my weight went from 30Lbs down to 4Lbs! This has helped my weight and balance dramatically. The engine cranks over much faster than with 2 Odyssey batteries and the alternator refreshes the battery to full charge with in minutes of run time. The extra crank power is very noticeable. We will see how long this battery lasts but based on history from others, I expect much longer use than with a lead acid battery.
