I have been running two Trojan T105's strung togther for three year's now.
220 amp hours. I have them under the back seat where the ECU used to be. I
put them on a flat smooth surface and added a little length to the wires so
I could pull them out easily to check on water. They have been flawless. I
have been using Trojan's for many year's now on a home solar system. Keep an
eye on the water level and they will give you absolutely no trouble through
a wide range of temperatures.

I also added a little vent.

I highly recommended them if you have the space. I have a Subie
engine/alternator so I think the input is 70 amps. I do want to get a solar
panel. Already have a Mark 15 charge controller which right now is just used
to show data. Merv.
