Has anyone seen or tested these? Wondering what their actual capacity/quality is. I would like to order a set of batteries to start my DIY battery build for our new RV. I have zero experience with Aliexpress so, naturally, I have reservations. The issues I keep running into are individual cell capacity vs shipping. Adding more lower capacity batteries adds so much in shipping cost, upping the individual cell capacity is the only economical way to keep shipping & overall cost down. I would like to be able to run the rooftop AC unit (1500-1600w running). So, I figure a minimum 7kw battery array should last the better part of the night. BUT these cells could easily power that load with room to spare at 420Ah/cell...mo powa baby!
