Jerry Work gave an excellent presentation on installing LiFePO4 batteries in the GMC at the GMCWS fall rally. I've included a link to it. It convinced me to replace my old CATV 12v batteries wired in parallel and also the combiner. So far it's looking good. I just wish I had more opportunity to try it out on the road. COVID rules. The only problem I had was that I formerly used the output of the alternator to turn off my fuel pumps if the engine shuts down. With the new combiner, which doesn't have a diode in series with the alternator output, it won't work. So I decided to mount a Ford collision switch near the wipers as an alternative. Better than nothing?
