Stacking batteries

[rwechsler]

I know that you can stack CR123A batteries and the such, but can you stack 18500 or 18650 batteries in a SS GGTS for a 7.4v vape (using appropriate resistance attys/cartos)?

Yes you can, but you will need the GGTS extension sleeve (for 2x18650 batteries).

Left to right:

Single 16340, Single 14500, 2x CR2 (15270), 2x16340, 2x14500, 18650, 2x18650.

If you have enough extension sleeves you can even stack more than two 18650 batteries in a GGTS.

Just make sure to label your batteries and rotate the order you stack them in every change to prevent one battery from taking all the strain.

To confirm, 2 stacked aw irm high drain 18500 stacked will produce 7.4v?

 

[k3v1n]

Yes rwechsler.

3.7v x 2 = 7.4v

Great, thanks Kevin.

Be aware that a 3.7v battery fresh off the charger is actually 4.2v

So two 3.7v batteries is actually 8.4v unloaded
