EarthX ETX104 Back Up battery provides power to your critical loads with built in current limiting!

The ETX104 back up battery is a lithium iron phosphate (LiFePO4)  4Ah  battery designed to provide back up power to your critical loads, (essential power bus or emergency loads). This battery can be used with any size charging system due to the built in current limiting to protect it from high discharge/charge current. This is not a starter battery.  

Our ETX battery series is fully protected by an integrated battery management system (BMS) that protects the cell’s from over discharge, over charge, short circuit, temperature, plus cell balancing to ensure charge levels are equal.  Additionally, our ETX Hundred series batteries have redundant electronic circuits and battery fault indication.   The fault indicator can be connected into your EFIS or wired to a 12volt LED light on your control panel (SOLD SEPARATELY) to alert you to the state of charge and state of health of the battery. (Please see manual for details)

Why choose an EarthX lithium battery? S    P    E    E    D

S=    SPEEDY CHARGING- EarthX ETX batteries will charge 2-3X faster than a lead acid battery.

P=   POWERFUL and LONG LASTING- EarthX ETX batteries life span is much longer than a lead acid battery and can last years longer!

E=   EXTREMELY LIGHT WEIGHT- EarthX ETX batteries are up to 80 percent lighter than their lead acid equivalents. Lighter weight = better performance! This saves an average of 2-3 lbs. for dirt bikes, 6-8 lbs. for street bikes and 10-20 lbs. for touring and cruiser bikes.

E=  ENVIRONMENTALLY FRIENDLY- EarthX ETX batteries are environmentally and user friendly. Nonhazardous, nontoxic, nonpoisonous. Will not sulfate, will not corrode, will not freeze, will not boil over, will never need water added and will not spill acid EVER!

D=   DISCHARGE RATE- EarthX ETX batteries have a much slower discharge rate than a lead acid and the need to charge them is greatly reduced.
