Converter Amperage Choices

Post by 85Chevota » Mon Nov 05, 2018 11:28 pm

Should I choose a 35amp or 55amp converter?

I've been studying up on the B190 electronics and am ready to replace the original converter with one of the new Progressive Dynamics replacement converters that now allows you to charge all battery types. I'll stick with lead acid for now and will add a battery bank under the couch, but as lithium prices drop in the future I'd like the option to switch to lithium so this seems like a good product. http://www.bestconverter.com/4600-serie ... c_133.html

My biggest question right now is what amperage to choose. This winter I'll be running the propane furnace, TV, 12-volt fridge, and other minor draws like charging a laptop so the 35amp option would likely be sufficient. Are there any drawbacks by just installing a 55amp converter? The price difference is only $10.

I may be missing something with my understanding of electronics.

This is what I went with 45 amp smart charging for agm and gell cell. It comes with a new filtered board for sensitive electronics it a direct fit for the parallax 6300 only replaces the lower unit. ImageImageImageImageImage

The 35 amp model should be sufficient, but no problem going with a larger-amperage model.

Thank you both for the info. I ordered a 45amp upgrade model from bestconverter.com. Planning a 72 day road trip this December with a lot of boondocking in national forest and BLM land so this should help with the charging from the generator and on the rare occasion I plug into shore power.

Good choice its well built and all steal case the other some have regrets after receiving it. Im told its mostly plastic im running two 110ah group 31's 220ah total. My testing has been good pulled the system down to 12.2 volts in 5 days of use it was recharged in 5 1/2 hours after plugging in. Good luck the new fuse board is a big help to.
