additional battery charger

just a cost reference
the 40amp Vector that some of us have, was Near $100 when it was available

no longer being mfg, don't know why, maybe NOT enough profit margin

i would not get anything less than 20-25 amps unless it was emergence have to have, i can't see paying $49 for a 15amp charger

“How many amps do yo recommend as an add on ?”

Batteries slowly lower what they will accept as the charging process proceeds. That’s why the absorbion phase takes so long. Solar is perfect for bulk, absorb and float.

MrWizard I have seen you on here for years and recognize your knowledge of electrical problems. I am glad you responded.
If I add a 25 amp stand alone, it is 25 more amps but still only 12 v or 13.6 volts. If I use the stand alone in addition to my WFCO 45 will I get a quicker charge ?

I will also be using a Wen 2000 I generator to charge. I have the direct 12 v charge cables that plug straight into the generator.
Would this be a better option ?

Probably not - read the owners manual or go on-line to find one. Most of the generators that use direct 12V charge cables only put out about 10A through them.

You will get only 8 amps output using the 12v charging feature.

Is it possible to, for lack of a better term, to "stack" the chargers ?
Meaning, if I plug the rv into the generator using my 30 to 20 amp adapter with the converter breaker on, and, plug a stand alone 25 amp charger into the generator, will they charge faster combined, or will 1 sense the other and cancel out ? Hope this doesn't sound stupid.

I also had a WFCO converter. It never went above 13.6 volts even when the battery was intentionally run low to check the converter output. I replaced the WFCO with a Progressive Dynamics 4135. I know that it is only 35 total amps but at least it does kick out 14.4 volts. I checked when I installed it with my voltmeter. My WFCO was brand new and rather than use the warranty to get another jucker, I spent the money on something I believe will be working for years.
I tried running the PD4135 with my Champion 2000i generator and my volt meter showed a good charge getting to the battery.

If spending money get the PD.

Have Randy overnight one to you. Or pick it up at a local dealer.

If you don't have time to install... just get some #6 wire and battery clips and just slap it on direct. Or cut some cheap jump cables and use that.

Plug into the generator and use the converter you already have to charge the batteries for the 4 days. It will not hurt the batteries in that short period of time.
