My charge controller is set to recharge my battery bank and begin a float charge at 14.4 volts. If I use some of my 12 volt components during the day while the batteries are charging, will this high voltage damage my diaphragm pumps and Arduino etc.?
I thought of adjusting the float charge level at the controller but someone told me that doing so will be bad for my sealed lead acid batteries.
I'm thinking of using XL4015 or XL4016 buck converters, but I want to maximize the power before reaching the 11.1V load disconnect..
And advice and correction will be highly appreciated.
Thank you so much!
