Well, I just bought one of these on Amazon with a 10% off coupon brought it to $421.72. That's just too good of a deal to pass up and take a chance on. Delivery (Jan 21 - Feb 11). So there is the rub, It's coming from china on the slow boat. The recent teardown of chinese battery packs have...

Fair enough! I finalized the order of cells with Amy. She's very nice and said that they are going to be shipping them out soon. I ordered double the bus bars to double the thickness up. Shipping cost went up two days ago. Corona..... Amy says that they are all doing ok. Glad to hear for sure...

ok, The Chargery BMS not controlling the negative is what is messing me up. It uses a contactor to isolate the battery which I really like. This is a drawing with the chargery and isolator.

For some reason my brain is farting on the cell layout. Is this correct? Do i have the BMS leads connected to the right cell in the pair? it looks backwards for some reason. What did I mess up? I pulled the trigger on 16 of these 280Ah cells. Installing them in my motorhome to replace the coach...

Sounds like I need to get an 800-1000w system is what youre saying. how much battery? What kind of batteries? It's a 2008 Class A Holiday Rambler 30sfs that has a pretty big battery compartment. It's in the basement middle of the way back and below the slide. The coach has a DC system built in...

What would you get if building a 400-800w system from scratch? I need everything, Post links if you've got them to the components you'd use to build up a system. My 30ft motorhome has a lot of room space for panels. Start off with four and maybe add four more. Maybe have a couple portable...
