Battery charging from shore power?
Stock, do most trailers charge the batteries when they are hooked up to shore power? Or does that occur when the trailer is hooked up to the tow vehicle?

The trailer batteries charge 10 times SLOWER when the truck is recharging them.
Maybe true if some configurations but not mine.
When the truck is running, the "trailer" batteries show about 14.3 volts. When the gen or shore power is active, they show in the mid 13's. I'd say the truck is charging them more.- Note to ALL, the OP bought very expensive AGM batteries, someone please explain to him researching brand of battery and suggested charging techniques, so he doesn't burn them up or dry them out quickly, and what their charging needs are before storage... AGMS need to be top charged quickly and always stored top charged before being put away.
- Read BFL13's post above. It made my day. 10% above cost versus 90% discount. Thanks Bluebeard. I've got a lot of irons in the fire and too many times I abbreviate a bit too severely.

Remember those 10-turn pots on the power supplies?
Try one of them on a DC to DC booster or bucker and Go To Wide Track Town.
With Muffin-fan cooling, 25-amps of boost is nothing to sneeze at. The Ugly WhiffCo is playing fixed power supply and Boosters and Buckers make it do what I want it to. It has no choice. Need 4.8 volts? Got it. Need .020 amps got it. Need 48 volts, 36 volts for LED's? Got it. Need it all at one time? That too. Beats lugging around a wimpy multi-tap adjustable power supply. Meters and 10-turn pots. - Mex- I miss your point....
- UGH!
Tried educated way. Got lambasted for using multi-syllable terminology. Now use sign-language, grunts, moans, frowns, and finger signology. - Ordered the Wizard. Thanks for the advice
- Really must have the wizard three stage controller for AGM.
Standard fixed 13.6 volts will chronically undercharge those batteries. - Hey guys, good stuff. So does the Charge wizard make the Progressive act like a 3 stage charger as noted in the following link? It looks like it would be the easiest way to upgrade. Pros/cons? I replaced the deep cell batteries with a couple of 6v AGMs that were VERRRRRRRRY Deep cycle- very expensive batteries, my solar friend said they were the best you could buy for this application.
