Battery wriring.

I have 4x 6V 12Ah gel cells that I'm going to wire up for a total of
12Ah at 12V (two parallel strings of two batteries).

The question is:

Is there any benefit or (or detrimental effect) of shorting the 6V point
of both series strings together?

** Have you thought about using ballast resistors ???

I think you only need two batteries in series to get 12 Ah at 12 V...

Easy way

+_______/ +[6v]- --- +[6v]- \_______ -
\ +[6v]- --- +[6v]- /

Double V double A

Arse. Yes that was supposed to be 24Ah sorry. Teach me to post after
Friday night knockoff beers. The question remains though, any
point/detrement to shorting the 6V tap?

I take it by your (other) sarcastic post you think this is similar to
electrolytics Pill?
 
Two in serial and two in parallel connection of four identical batteries is
the way to go - standard practice.
There are some considerations if there are more than two parallel links of
batteries....

I think that is what he is suggesting - he's asking whether there would be
any effect if the middle wires were connected together, ie. making it a
series string of 2 pairs of paralleled batteries.
 
No determental effect while batteries are delivering power; but could be a
problem when charging -- the battery with the lower internal resistance will
tend to charge better, so oyu don't really get a "proper" full charge.

Yep that's what I was asking.

Cheers, I won't do it then.
