I'm new to this site so forgive me if this has been discussed somewhere before. I'm wondering if anyone out there has tried using this type of device:
It solves one major problem of trying to charge your TT battery while in tow. As many have found, the tow vehicle alternator is a long ways from the TT battery and thus there is considerable voltage drop. Many report only 12.0-12.5 volts getting to their in-house battery. This is not enough to charge the battery completely.
I've seen many attempts to solve this but the DC-DC device above seems to do the job. I can run on 10-15 VDC input and has a well-regulated (smart) output circuit.
My only complaint about it is the 7.5A limit on output current. This is plenty to charge a battery but not enough if you want to also run some things in the trailer while towing like the refer at the same time.
Has anyone used this type of device or know of one with more capacity on the output? I want a smart device like this one that knows how to charge the particular battery technology and then maintain it at full charge.
Just connecting a solar panel up to trickle charge sounds good, but it is not the best way to get peak performance and lifespan out of a battery. A good AGM battery can run $150-$200 or more. I want to get my money's worth out of it. A high-output solar setup is $$$$.
