seven pin>charge controller>marine battery?
« on: November 15, 2017, 09:30:03 PM »
Would it be possible to tap in to the 12v from my seven pin and charge a marine battery via charge controller?

It's possible if the battery is almost full to top it off
 However if it needs a good charge the answer would be no. It would take days if not longer and it would be bad for the battery long term if continually charged that way.

  Thank you for your reply! I'll invest in a solar panel instead.

Most 12v lines on the trailer connector have an amp limit, but it varies with the vehicle. 10A-20A is typical, but I've seen 30A too. Most trailer side connections connect that +12v direct to the trailer battery (no controller), so you get some charging whenever yu tow.
