2 questions on charging & monitoring batteries.

Hi, hope you can help. I will have one starter & 4 leisure batteries & would like to charge via mains/alternator/solar is there a diagram around that might show the the best way on wiring on this. Cant seem to find one for 3 inputs.

As there will be 4 leisure batteries, is there a way to monitor the condition of each battery individually without having to disconnect & test each one. IE: 4 meters via 4 diode or similar.

Thanks

Chris

Hi Chris, and welcome to the forum.

Crikey, you must do some serious wilding with that battery bank!

There are a number of battery nerds on here who know all there is to know so you should get your answer soon.

I use a small LED digital voltmeter gauge to the batteries (one for the Starter and one connected to the leisure battery) to keep a visual check - is that what you're after ?

I had one chassis and four house batteries in our Hobby 750. Never bothered about regulating the current and just plugged into mails or allowed the solar to keep everything topped up.
Suck it and see would be my answer.

Hi, yes, this sort of thing, but would also like to monitor the 4 leisure batteries & wasn't sure how to isolate each one to see if one is not so good. So, like yours, but would end up with 5 meters, or 2 meters & a rotary switch to view the voltage on each on of the leisure batteries. Possibly using an extra shunt or diode or both to read individually.??

I doubt you could monitor individual batteries while they are connected together. It would only show the average collective volts.

Overall you will get a reading from the lowest performing battery when connected in the bank. To monitor individual batteries you will need to disconnect, let them rest then take a reading....which is impractical!
