Note: Not FAA Approved. Intended for use in experimental aircraft only. The ETX680C lithium battery only weighs 3.9 pounds but delivers 680 cranking amps! This battery is intended for 400ci engine size or less; 60 amp alternator/generator or less. The ETX battery series is fully protected by an integrated battery management system (BMS) that protects the cell’s from over discharge, overcharge, short circuit, temperature, plus cell balancing to ensure charge levels are equal. Additionally, the ETX Hundred series aircraft 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 to alert you to the state of charge and state of health of the battery. (Please see manual for details) Note: The difference between the ETX680 and the ETX680C is the physical size. The “C” is for the compact. |

At least 50% more RPM on starting I can sure you the BMS system saved the battery as I mistakenly left my master switch on for a day and after recharging the battery all is well

Installed in my RV6A.. Works great!! Talk about some cranking power, well worth the money.
