Dc to DC Converter Between TV and AS

Hi Team,

With my LI battery upgrade, I installed a Renorgy 20 Amp Dc to DC Power Supply (nice unit, about $120) between the TV and AS. It went in the AS, near the battery bank. It is multistage and LI Compatible. It works with voltages from the TV of 8 to 16 volts. Providing appropriate voltage for multistage charging of the LI Batteries. It is necessary to keep the higher voltage LI batteries from bleeding charge to lower voltage TV lead acid batteries.

Overall, I am happy with the performance. Via the Bluetooth Battery Monitor, I have seen it charging the AS batteries with 10+ Amps.

Even with lead Acid batteries, it might be a good thing to install. Helps overcome any voltage drop in the TV wiring and provides the appropriate voltage to the battery.

I have certainly been thinking about adding one of these. My truck puts no charge on my lead acid batteries when towing. It would sometimes be nice to capture a little charge when moving. Thanks for posting,
Do your instructions say wha the input amperage ought to be or what size wire the TV should have to the unit? Did you hook it to the hot wire in the 7 pin or run another wire with connectors?

The DC to DC Power Supply will work so long as the input voltage is 8 to 16 volts on the input.

"Did you hook it to the hot wire in the 7 pin or run another wire with connectors?"

Pin 7 was already run to the bus bar that my battery bank hooks to. All I needed to do is disconnect it from there and run it to the input of the DC to DC Power Supply then run the output of the DC to DC back to the bus bar.
