120Ah incl BMS $365 incl shipping from Aliexpress

[JohanB]

Hello from Sweden! This is my first post here. I am about to build my first RV system and found Wills videos on youtube and eventuelly this forum. So this is my first post. After some research I pretty much decided to go for trying what you guys call "Blueys" 150Ah + Daly BMS from BLS. As I was searching Ali Express I stumbled upon this 11/11 discount deal. Dirt cheap 120Ah in a metal suitcase kind of packaging with really good reviews. Has anyone tried these? So why not use these instead of building my own system? It feels like it must be something I'm missing. Kind of a newbie on this and still learning Thanks

9.6 volts as a low cutoff is too low. You would need a separate low voltage disconnect.
