I just put a 12V light bulb from a car tail light on the high cell to keep it's voltage down a little.

Wow, they were less than $200 new.

Or....buy a $60 600-700W microwave and use your existing set up.

Look for a used hobby charger. I've got a Hyperion Super DUO 720i that can charge/discharge between 1-14 cells. Max charge rate is 20A, max discharge 5A. It balances all cells at the same time. Max voltage is adjustable from 3.60V to over 3.65V/cell. It will storage charge at 50% capacity...

Curious, in a parallel/serial battery set-up what carries more current, the parallel or serial connection?

Not too sure exactly what your asking, but you can connect the BMS wires directly to the negative battery terminal and the other side of the BMS to the smart shunt, then the other side of the smart shunt to your loads (or negative bus bar). It's also OK to hook the smart shunt directly to the...

Think through the problem. Do you already have the 2" pipe? If not, buy some that's already threaded. If you already have the pipe, is there another way to connect them without threading? Can someone else do the threading? Can you use a different type of pipe altogether?

I've actually seen your van build on FB. Super nice! How do you plan to fasten the battery pack to the van?

For some reason it's hard to find much info on that unit. I guess there aren't many using it.

Will might have made him busier than he wants to be.

I've got the same cells from Basen. Grub screws would thread in about 3 turns. I made a bottom tap by cutting down a standard tap and cut the threads until the tap bottomed in the hole (I measured the depth of each hole before tapping). After cleaning, I could then get between 3-1/2 to 4...

Sorry, missed that. Yes, 24V. .85 is to take into account inverter efficiency. Use whatever your inverter specs out.

1800W/.85/12 = 176A. The BMS likely won't handle that load for long. Sounds like you need a larger BMS or lessen the load.

Don't know if you'll be using a DC-DC charger in your van, or what kind, but I planned to use 18AWG for the remote switch running from the back of my van to the dashboard.

2/0 AWG isn't tooooo far off from 18 AWG :LOL:
