Washam84 Posted June 5, 2023 Report Share Posted June 5, 2023 Looking to make a RT91 or btech amp, a battery, and solar panel to make a field operable gmrs. What are you guys using to make this happen efficiently. I'm looking at an 12v 6ah lithium battery with a 40w panel. If heard the amp will draw 5.5amps.

You'll need the right charge controller for that battery type. You can look at these. https://sunforgellc.com/product/gv-5/ Look under the GV-5-Li spec's tab. I think the one you want is the GV-5-Li-14.2V model for the Lithium Iron Phosphate type battery packs. The solar panels from these guys seem to be reasonably priced. The 30 watt panel is likely the largest you would want to carry around. https://www.renogy.com/30-watt-12-volt-monocrystalline-solar-panel-new-edition/ If you're looking at the folding semi-flexible solar panels, the ones that fold up and can fit in a backpack, those are nice, AND expensive! https://www.powerfilmsolar.com/products These guys are good for the battery packs. I got the 4.5 ah and the 40 ah packs. https://www.bioennopower.com/collections/12v-series-lifepo4-batteries I've purchased the items above myself, except the folding panels, so I do know they will work.
