I agree the Renology part is good (and pretty much necessary) as it performs two functions (especially in relation to LiPo RV batteries). It increase the Voltage as, yes, that is needed to actually put charge into the batteries AND it is intelligent in that it steps thru the 3 phases of battery charging and adjust the voltage according.
My whole original response, and what I was still trying to explain, is that the Renology part does NOT and can NOT boost either power or specifically current "magically" when used with a tow vehicle that can only put out 6 amps. That is what I was (over?) reacting too.
The OP latter responded with perhaps not a good choice of words.
I just didn't want anyone thinking they could get 20A of charging out of the Renology device while the vehicle was limited (either due to Alternator output, wiring or fusing) to just 6 amps.
Then the other people posting confused me more in some cases, so I continued to try and clarify (but I guess I failed)..
I apologize, as hopefully we are all together now. Renology DC to DC Battery Charger is a good part of the solution. But it doesn't fix if your tow vehicle charging design is deficient. A user needs to understand if they want to provide 20A to their batteries from Renology part, then they need to provide (at least) 20A from their tow vehicle.
Thanks,
