Thanks for the response, I'm learning that now, the ruixu says it'll charge at -20 in the documentation, guess what, it wont, I had to set up a diesel heater in the back of my van to get it above 0 and they finally took a charge, and ruixu support ghosted me.
I also received my dawnice...
Also looking for an update, just placed an order for 2 16kw, one thing in concerned about is they're not heated like my ruixu 16kw, how low temp can these charge and discharge?
