Hi Guys/GalsI have a 25' Weekend Warrior toy hauler and last week in Baja my my Iota DSL-30 converter/charger stopped workingI bought a PowerMax PM4 100A converter/charger to replace itI was thinking about just putting it in the same spot as the old converter/charger but I started reading around and most said to move it closer to the battery.It got kind of confusing on how to do that, they said to run power from the breaker that supplies the converter to the new location and use the existing wires to run the power back to the fuse boxI don't get that partI'm also going to be replacing my one 12v Deep Cycle with two 6 Volt deep cycle batteries, that part makes sense to meCould somebody help clarify the moving of the converter or if it's just ok to replace the old one in the same placeThanks!Here's a picture of what I have, sorry for the multimeter in the way, I took the photo when I was trouble shooting the problem

You should be fine utilizing the original location. Any gain from moving it would be minimal if you have large cables.What size cables does it use? My WW came from the factory with 4 gauge from batteries to converter.

PM4 is well known to drop to trickle charge at about 3/4 full. Probably even less with 100 amps into just two batteries. Fine if plugged in but not so good on generator unless it runs all day. Possibly you purchased a manually controlled PM4?Since 100 amps is probably too much for the existing circuit you may as well mount it close to the battery with #4 or better 12v wire.

You are replacing a 30 amp converter (single 13.6v unless you had the IQ4) with a three stage 100 amp converter but only getting two 6s. Two 6s can accept about 75 amps to advantage, 100 is too much, but would be ok with a bigger battery bank.The 100 amper is borderline for needing a 20a 120v circuit but will work on a 15 but maxes it. You don't have to use the same 120v circuit as the old converter at the new location. Any circuit will do--but as above, with nothing else on it running at the same time as that 100 amper going full out at 14.6v. With just two 6s it wont be doing 100amps at 14.6 excpt at first, then it will taper amps quickly and drop to 13.6 too. But you could pop a breaker right at first if something else is on.

So should I pick up a smaller converter/charger?
