Agreed that the Bargeman is good for a top up towing for an hour or to charge a depleted battery over many hours while driving.
We were having a discussion on another thread
(Surplus Current?) about charging through the alternator but no one had any data. I assume that you are idling your truck for a few hours to charge the trailer batteries. Have you had a chance to measure output using this method?
If you are so inclined, starting from 50% SOC, how many volts and amps can be measured at the battery after 1 hour, 2 hours, 3 hours? And, how long does it take to reach 100% charged (after taking off the surface charge)? This would be really interesting to see.
