RE: Help with Triton2 charger
Oh - the button on the charger!
Yes, once you get the charger set correctly for the battery (your description sounds correct), then you need to press the button STRAIGHT down and hold it (without turning it at all) for about 2 seconds. It will beep immediately when you press the button, but you need to hold the button down until it beeps again and starts charging. Then it will "look" at the battery and if it seems okay you'll hear a boo-beep signal and away it goes.
If the battery is not correct, you'll hear a bee-boop sound and there will be an error message on the screen.
But you still need to have the balancer in the "Interface Mode" before the charger will work through it.
Can you post a photo of your setup? Maybe that would help.
