I'm looking for an intelligent battery charger that can charge 6v

in series with its 12v setting - is this possible?

Whyever not? A 12V battery is only 6 cells in series, the same as
two 6V batteries in series is.


Otherwise I need to
recharge a pair (or quad) of 6v 12AH SLA batteries with ability to
leave them connected on float with no overcharging possibility. A bonus
would be the ability to charge 2v and 4v batteries.

If you can connect them in series, again, there's your answer.


Ideally I'd like to
use 2v lead acids - where can I get these in the UK? thanks, Andy

Dunno. Can you still get car batteries with external connections
between the cells?
