We are creating a hybrid mongrel battery for our RV. The system will have lots of solar, and both lead-acid and lithium batteries. We are going to load up the RV with lots of lithium batteries and eventually put as much solar on the roof as possible. By the end of the week, the rough fit …
For the second time in our two and a half years, while traveling full-time, we were unable to depart on schedule. This time the starter battery was dead, the previous time was a dead starter. I am starting to notice a trend. As for the battery, we drained it, not knowing that it was draining. …
At the Xcapers 2020 BASH we took the opportunity to gather user inputs for our Solar Test Data Analysis. There were 400 RVs and no hookups for more than a week. These are the lessons learned. We gathered results from the Bash(ers), usually on a daily basis to see how our friends were able to …
As you know, the Xcapers Bash is 100% off-grid. Many RVs have solar to recharge RV batteries, some only have generators. This represents a huge opportunity to get same-day, same-weather, day-by-day electric data from hundreds of RV battery users – with and without solar recharging. Thanks for contributing to the Xcapers Bash Solar Data Collection. …
Which should be first, solar or lithium? My install could have been done, either way.
