Battery, charger or boat issue??? I have a 2020 Z18Pro with 10' Talons, Ultrex 24 volt and just two Helix 7's. I noticed toward end of day my Hummingbirds were shutting down with low voltage warning. Boat came with a NOCO Gen3 and the main battery is an Interstate 31M-AGM CCA 800 and 1190 MCA. I keep the charger on 24/7 when not on the water and yesterday I noticed all my Talon lights were both blinking. I checked the charger and see the flashing error on the main battery bank. I checked the voltage on the battery and it had dropped to a 2.4 even after being on charge! Drove off to an authorized Interstate Distributer. After checking the battery and looking at the charger he's telling me the problem isn't the battery it's either the charger or something in the boat drawing AMPS. He said the charger is not designed to charge and maintain the AGM31 if the AMPS drop too low…I spoke with NOCO and they say it's not the charger it's the battery. What's your opinions?? What in the boat could be draining the battery while it sets for awhile but always on charge?? Frustrating to say the least! Thanks for all your knowledge..
