I’m still a bit new to batteries and electrical etc so I Emailed a few questions to the current connected team, they were extremely helpful and fast responding. I was a little hesitant to buy from current connected at first since I couldn’t find any reviews etc besides a couple YouTubers suggesting them but after working with them I’d definitely come back. The server rack eg4 batteries were like $300 cheaper each which scared me cuz everyone else was way more expensive (I couldn’t stop thinking “they’re so cheap, what’s wrong with them?”) but I got the batteries and wired them together and everything worked so I guess everyone else was just being greedy. No programming, no computers, plug and play which is how stuff should be. If anything was programmed then current connected did all that before sending them to me. I tried to make a review months ago but the website here was bugging so maybe it was bugging for everyone else and that’s why there aren’t a lot of reviews. I’ll buy again. Definitely recommend. Batteries came well packaged via R&L freight carriers.
