They'll work fine in parallel. Just be careful not to charge the
batteries too fast! I like to charge at 10% of capacity to get a
good, deep charge. 700AH - 70A charge for 14 hours from dead.

Others will tell you it's 25% but that gets too much "surface charge"
without restoring the plates very well.

The slower you charge, the better.

If you have a 50A load on them, just subtract it from the available
charging amps.

The 40A old AMEL saturable reactor charger my captain took off his 41'
ketch is now nicely charging my shop house batteries in my Union City
29 stepvan...(c; Man, that thing can put out the POWER!.....

It's dual full-wave rectifiers also charge the house batteries WITHOUT
generating a lot of switching noises to screw up my shop.....

gallons of kerosene per hour over the USA. R-12 car air
conditioners are responsible for the ozone hole, right?
