Battery charge questions

I had one of those a few years ago. It is a 4455TC IIRC. Specs on their site. You must install the TC module to get stages. Otherwise it is single stage at 13.x. The TC wire to the battery has the sensor on the ring terminal that goes on the neg battery post IIRC.

I got 60 amps from the "55 amper" using #4 AWG wire to the batts. With #8 it only did the 55. It worked as well as the Iota a guy on here had when we did a "shoot-out" contest.

It did more like 14.2v rather than the usual 14.4, but it still got the job done.

I'm having a tough time finding the specs on the 3 stage Parallax charger.
I installed a Progressive Dynamics converter on my previous motorhome and they very clearly spelled out the specs for each stage.

Good solar charge controllers come with a temperature “probe” to be placed near the batteries.

Charging voltage varies depending on temperature. See your battery manual at page 19. I don’t recommend going by what you’ve heard.
