Keeping batteries in series in balance

Start saving your money to replace the carbon batteries.

Not a fan of the carbon batteries ? From what I read they have much better life and can be discharged to a higher rate than lead acid.

I am a big fan of Lithium and have made several smaller 18650 packs for some RC stuff that have preformed amazing. Will be for down the track when we are living on site but. Need something a bit more off the shelf for now

Hi, Going to set up a total off grid solar system for our holiday house that is in a remote location. Going for 1.8kw panels and was going to get 4 x 200ah 12v lead carbon batteries

Hi, Going to set up a total off grid solar system for our holiday house that is in a remote location. Going for 1.8kw panels and was going to get 4 x 200ah 12v lead carbon batteries in series to get 48v to keep the current down.
As we will not be on site for a lot of the year I am concerned about not being able to keep a close eye on the batteries and making sure they stay balanced. Is there a way of making sure the 4 x 12v batteries stay balanced within the 48v series system ?

Charge using the voltages and times recommended by the battery manufacturer. They will stay in balance. Lead acid batteries in series "self balance" during charging.

If the batteries are wired in series they will stay in balance on their own. Even in parallel on a system that spends most of it's time in float they won't tend to get out of balance.

That's going to need to be 4 , 12V batteries in series, to get 48V @ 200ah

2 batteries will get you 24V @ 200ah

Sorry Typo meant to be 4 x 12v. Got it right on the second half of the post Have edited thanks

t 2 x 200ah 12v lead carbon batteries in series to get 48v to keep the current down
