![]() We were able to replace the dead AGM lead acids with two 75Ah Battle Born lithium batteries for a total of 150 amp hours of usable power. This only cost slightly more, which was worth it for the extra benefits. And no longer had to worry about poisonous off-gassing from a lead acid battery right under our bed.īecause of the supply chain issues and relative high cost of two new same AGMs, we recommended our friend upgrade his RV batteries to lithiums. We also saved on weight with the lighter lithium battery. It offers more true available power, and the battery power does not significantly diminish if drawn low. This is especially so when you consider that lithium recharges faster. But when out camping, we prefer to use batteries and solar when possible.īy upgrading the lead acid battery in our Casita to a 100 Amp hour Battle Born lithium battery, we more than doubled the available power (2.3 times). And sometimes we brought a portable generator for longer stays, like at the Albuquerque International Balloon Fiesta. We usually carried a small portable solar panel which helped capture energy on sunny days. When you consider water pumps use four amps per hour, furnaces use eight amps per hour, and all of the other draws, those 44 amps can go quickly. When you factor in that only 50% of a lead acid battery’s rated power is available to use, that meant only 44 amp hours. The original battery that came with the Casita was rated at 88 amp hours. Especially as we were used to the comforts of the much larger battery system in our Class A motorhome. But with just one small lead acid battery from the factory, we felt a lot of limitations and battery anxiety. Many of our trips with this camper were boondocking. We bought our Casita camper trailer primarily to use for short getaways. ![]() But that’s a lot more power than you may really want. And use all kinds of household appliances and tools in our daily life. That setup enabled us to boondock for extended periods in our full time RV life. If you want more information about that power system, you can check out our article and video in Episode 5 of our RV Makeover Series. That was a significant investment in time and money, resulting in a powerful and life changing upgrade. That system included adding 600 amp hours of Battle Born Batteries (6 x 100 ah batteries), plus 1020 watts of solar panels, new inverter, converter, charge controller, and massive changes to the wiring and electrical system in the RV. We were even able to do our Ultimate RV Makeover powered entirely by our solar and lithium batteries. This was a huge upgrade that completely transformed our RV into an amazing off-grid home on wheels. If you have been following us for a while, you probably know we did a massive lithium battery upgrade in our previous Class A full-time RV. Note: Coupon Code RVLOVE offers discounts with Battle Born Batteries. ![]() But some of the above benefits can benefit every RVer, regardless of how you use your RV. Those who would not see as much benefit likely spend of their RV trips hooked up to power in a campground. With lithium having so many benefits over lead acid, it is easy to see why you might want to make the swap.
