Mixing different batteriesin 3vo mod

[Lonewolf333]

I currently bought a 3vo mod and bought some trustfire batteries as a second pair. When i try to put them in together i cant close the battery cover. Tge trustfires are 880mah and the ones that came with the mod and 700mah. They are both 16340s 3.7v and if i put one of each in they fit. Is it safe to mix different mah lvs?

Also i have some tenergy rcr123a 3.0v lifepo4 batteries that fit but do not know if safe to use.

Thanks in advance for input on this.

I would never mix batteries of different size, brand, mah, anything. I buy my batteries
in pairs if I want to stack them, check the voltage of each with a meter before use, and
if one goes south, ditch the pair. The cost for batteries is less than I spent for one day's
worth of smokes.

The short answer is NO! *Never mix batteries* of different types, voltages, charge levels, etc. That is my understanding. These things can be quite dangerous (as in "potentially lethal") when mishandled or misused.

I'm no authority on this but until you acquire more reliable & complete information my best (and strong) suggestion is that you avoid using any unmatched batteries together in anything.

I have been marking my pairs of batts in numbers to know matched pairs and oldest to newest in addition to checking voltages.

Anyone else have tips for this?
