Lithium Battery Upgrade

Good morning, what battery did you got with? I'm from NJ but vacationing in Colorado, Outside of Leadville,Co in a national forest CG and its a 100% service free- not even water.. and were loving it.. Last yr I added a Chins Lithium 200hr battery with a 2500w PSW inverter to operate hi load items( coffee pot, hair dryer and as of now our sm space heater -for above 9,000' our furnace wont cycle right and this morning its 45*outside and woke to 62*inside, so we made coffee and plugged in my heater an hour ago... Since the Chins worked so well I decided and so glad I did, that just before we left I had added a Power Queen 100ah battery in the front frame to run the whole RV's 12v system. To keep them charged we have solar.. We bought along our Gen, but it sits in back of the Truck. So far we havent used it yet in our 18th day of travel.. You hear of spending Thousands to have a Lithium system, but no its not. a 100ah lithium batt. 320$,100w panel 68$-controller 36$, wire and terminal ends I had.. I bought through amazon and on sale plus my time 425$ we spent. Note the 200hr chins/Inverter is a separate setup stored under the bed for our Hi-load needs- as a experiment to learn by.. In the winter the Batteries comes home and rest till spring.. Remember keep it simple and it will work..
