IMPORTANT – To vape at high power levels it’s NOT necessary to use stacked batteries. Stacking batteries is for advanced vapers who observe strict safety precautions. Failing to follow any or all of the following advice can lead to batteries venting or exploding. Please read the information carefully.
Stacking batteries is a way of delivering a higher voltage to the atomizer. So, two 4.2v batteries in series (stacked) will deliver 8.4v. Stacking batteries is safe, provided you follow the rules. Always stack the batteries in the right way – with one battery’s positive button on the other battery’s negative contact, and in the right direction – battery’s positive button to the positive center pin.
A) Keep your batteries in pairs
Mark your batteries to help you recognise that they’re paired. Use an indellible marker to label each pair of batteries (A, B, etc).
B) Keep an eye on the voltage levels
Test their voltage level as they come off the charger. They should read the same.
C) Alternate which battery goes on top
This helps keep the batteries balanced. Power is drawn from the batteries at slightly different rates when stacked, so alternate them between charges to even it out. Again, mark your batteries to help you recognize which is which. For example – your pair of batteries is labelled A, and each battery is labelled 1 and 2.
D) Do not exceed their amp limits
A pair of 10 amp batteries in series still has a 10 amp limit. Typically when using stacked batteries you would build a coil of higher resistance. You can deliver the same amount of power (watts) but at a higher voltage and lower amperage.
E) Change the batteries at the right voltage level
Voltage drop may be slightly lower when stacking batteries, and voltages remain relatively high even when the batteries are almost flat, so it’s important to keep an eye on what the batteries are putting out. Again, test them both without load and under load and stay well above the bottom limit of the batteries. So rather than change a single battery at 3.5v, you would change a pair of batteries at 7v.
F) Atomizer Resistance
Central Iowa Vapors does not recommend using an atomizer with a resistance below 0.5 ohms on Stacked battery mechanical mods.
Note: A Tank should never be used on a Hybrid Mod UNLESS it is Specifically Designed to be used on a Hybrid Mechanical Mod.
