DIY Regulated Box Mod

You have power and charging going to the output of the board. I assume you drew this that way for simplicity, but they are not the same. Additionally, you MUST have fuses for lipo setups. I recommend two LF700 fuses per battery.

Also, would you be able/willing to show me the best way to wire this together with the fuses in the pic as well? My brain is currently overworked.

Two fuses stacked in parallel on each hot leg, prior to the hot legs joining:

Works with 0.3~3.0 ohm atomizers; Input voltage: 3.2~4.3V; Input current: 1.5~12A; Output voltage: 4V~9V; Output current: 10A (Max.)

With a 10a max, you could probably go with the 50's (again, four of them to get to 10A hold on each leg):

I recommend you read this and then decide on the LF part you need:

You want near 10A on each leg, so you will want one 10A hold current fuse or two stacked fives.

Okay, as I tend to do sometimes, I have overthought this process and muddled up my mind. Can anyone kindly show me the proper way to wire this up using the blank diagram here? I would greatly appreciate it.

Join the two negatives of the lipos. Cut the two positives in the middle and solder your fuses inline, then join the output leg after the fuse so you make a single pack...like my image (adjust the length at this point so you have enough to reach your board, but not too much). This goes to the positive/negative battery input on your board. The atomizer is hooked to the output of the board (often a negative voltage) and the ground connection on the board. The charger can go to the positive and negative battery connection at any point (on the board or on the battery).

It looks like the vamo board has a common ground for the atomizer and the battery, so you would use the same terminal for them:
