Hi,
I have 2 x 12V 240AH AGM batteries wired in parallel that are used to start my starboard engine and also double up as the house batteries on my boat.
One of the batteries recently started to become very hot and was constantly drawing 16amps from the charger, upon removing and testing, it still reported plenty of CCA, Voltage and current draw were still good but the casing was showing signs of deforming from heat stress.
I've since decided to replaced both batteries to be safe and now looking to add battery monitoring and solar charging as none currently exists in the boat.
In the picture attached/below is how I believe I should wire up 2 x BVM712 and a MPPT100/20 so I can monitor each battery independently.
I would expect I need to set each 712 up as 240AH and will each one report correct SOC, Current Draw/Charge for each battery rather than as a battery bank?
While I could monitor the bank with only 1 x BVM712, I want the ability to monitor each battery independently
It may be an overkill but am I going about this the right way?
Thanks Paul
