We don’t reference many videos on this forum, because we prefer to develop and test our own theories in our own conditions. However this video is very well put together and full of good information.
Things worthy of note BEFORE watching…
- EV conditions are significantly different to RV conditions.
- The tests performed have been done at high C rates, which is not typical of RV use.
- Testing has also been done at high temperatures, that many of us will not experience.
- Be aware of when he switches between discussing LFP and NMC chemistry, it’s easy to lose track.
- While operating at lower SOC ranges is better (for longevity), it’s also worse for available capacity. You need to base your required SOC on your usage. If in doubt, just charge to 100%. It’s no use only charging to 50% if you need 75% of your capacity.
- The tests were focused on degradation, and for RV use we’re not particularly concerned with degradation. PowerPaul batteries will more than likely outlast your ownership of your RV.
- Spend some time reading the comments, there are some excellent responses in there.
- The most important thing he mentioned, is the need to regularly charge to 100% to maintain SOC accuracy.
- References for the tests are listed in the text on YouTube.
PowerPaul suggests storing your batteries in the mid-SOC-range if you’re not using it for an extended period (4+ weeks). This should ideally be done with the batteries completely disconnected from the system (via a switch or cable disconnect). If you use your RV every few weeks, store it at anything between 25-100%, and ensure you top them up before you go on your next getaway. If you manage to fully drain your batteries, recharge them ASAP, leaving them at 0% SOC for extended periods is detrimental.
