Will soon be installing EarthX battery, model EXT680. This LiFePO4 battery includes a BMS (battery mgmt sys) w/ LED battery fault light indicator to alert you to cell health and state of charge. I'm wiring this warning into my G3X display via Garmin's GAD27 unit. Added wire from Pin #13 in the J243 connector on the GAD27 to use the Discrete #5 function (programmable alert). Stein Air provided pre-pinned brown/blu stripe wire. I opened the 50 pin connector, inserted new pin into #13, routed in wire bundle to center, then forward to RH firewall opening along with MAP sensor wire. Will connect once battery delivered. [Note: BMS includes over discharge protection, over charge protection, short circuit protection, excessive cranking protection (temperature sensing) in addition to integrated cell balancing technology]

Re-assembled and re-installed onto GAD27.
Whole process was easier than I'd anticipated
