FREE (for cost of shipping) WFCO converter model WF-8735-P

I replaced our WF-8735-P with a bigger, higher current, auto-detect model to go with our new large LiFePo4 battery.  So the old one is available for shipping cost.  It was working fine when I took it out.  That's the model that many (most?) Aliners came with I believe, probably other brands too. Ours is a 2021 Aliner Ranger 12

The "-P" indicates it's the model for lead-acid (AGM, marine, golf-cart etc) batteries, so not ideal for lithium, but it does work, sort of.  Do your own research if you have a lithium battery, I'm not an expert.  The models with "-AD" in the model name are the ones designed for Lithium batteries.

This doesn't come with tech support, sorry, maybe best for people experienced with RV wiring. There are Youtubes covering the install, in case that inspires you to give it a try. I was a beginner before I started this upgrade on my trailer but it came out great with the help of Youtube.

Shipping will be about $20 in the US
