Just set up a new battery bank in a 24V configuration 2S2P.
I've got the panels going through an epever controller and flicked on the first time last week to start charging the battery bank before I swap out the old batteries.
However after a couple of hours of charging, I noticed that I could hear bubbling from the battery bank.
I believe this was supposed to be bad for AGM batteries, although I read that they are designed to reabsorb the hydrogen back via a catalyst if they are not overcharging.
See https://homebatterybank.com/is-it-normal-for-my-battery-to-bubble-when-charging/
This is what the app was telling me at the time.
14.6v is the recommended boost charge voltage for these nomad E2 batteries. As you can see, it was only feeding 10A into the bank, which I wouldn't have thought would have been an issue.
Will the batteries be OK, or should I lower the charge voltages?
Float voltage is set to 27.6V
