So I got the Thunderstruck and a contactor, but their wiring diagram in the manual appears to include a separate 12v source for the BMS and Contactor from the Valence battery. Can I use the Valence itself as the 12v source? Is my attached wiring diagram correct? Thank you!

Youve explained this all very well. I've spent all morning reading your other posta and other info and believe I understand all. One thing I'm lost on though, the Thunderstruck wiring diagram indicates that the LV contactor should be wired in line with the negative returning to the battery...

I read the other thread, and a few other things about contactors. The Thunderstruck BMS says that it protects from low voltage. Doesnt that mean it will shut off the battery when voltage gets too low? Why would I also need the contactor? And if I do, can you point me to an example of one? . I'm...

Thank you! I do have a 30A charge controller. There also is a 1000W inverter. But I get what you're saying about the DC connected stuff. I've already camped 3 days without exhausting the battery (went down to 12.7V) and that was on cloudy days. I've also obtained a 2000w propane generator just...

I'm just getting started with solar and learning what I can so excuse the simple question. I have one of these U27-12xp batteries on my travel trailer being fed by a 100W panel (which I plan to expand). The question is, am I OK using this single battery without the external BMS? What if I add...
