Bargain lithium battery.

[Drover]

While the subject is on batteries I'm after advice..
115 ah and 130ah joined as 12 volt .
I do understand that this is not advisable but would a battery balancer work ..both are lead acid leisure.
Google says as the difference is small it's OK to do..
Any advice would be appreciated.

No problem, safe and leave as is.

Perfectly safe assuming both batteries are OK and don't have a cell down, same voltage (12v) and the same chemistry (don't mix GEL and AGM etc)
They are connected together pos to pos and neg to neg, therefore they find their own equilibrium and MUST balance automatically. Just like 2 tanks of water sitting side by side, if they are connected by a pipe then it's impossible for the water level in one tank to be higher than the other.
One final thing, when you join them up make sure they are charged to approximately the same level as each other. If you don't then the balancing current that I mentioned could be quite significant as the high tank drains into the low tank. (The higher charged battery drains into to lower charged battery) In order to attain equilibrium.

Thanks to Trevskoda and Merl ive just saved around 30 or 40 quid.

I always like water/electric analogies, great way to demonstrate an invisible quantity.

So water and electrics can sometimes mix!

As long as you don't mix them together

Isn't an analogy a pre-digital measure of electricity? Probably explains why Mr Roger Conibear told me not take O Level Physics, because I would be wasting the Examiner's time ...
