24VDC Battery Back up - with 2 x 12VDC - 100Ah Batteries - monitor and charge options.
2 x 100AH deep cycle batteries - wired in series.



Can I use 2 x 12vdc trickle chargers to keep them charge?
Can the 12vdc chargers be connected permanently while connected in series?
What can I use to monitor each battery?

This is to be used for a large Reef Fish Tank.
When the power turns off it will run 4 x 24vdc pumps.

I have the switching units that turn off the mains and turns on the batteries 24vdc during a power cut, so no problem there.

I would like to have a display monitor for each 12VDC battery... what options are there ....
Is this suitable?

Thanks
