Dual batteries should always be the exact same and married. Married meaning you use them both in the same device, at the same time, and charge them the same way. It's a good idea to mark the batteries with a permanent marker and give them some kind of name like "set 1 a", "set 1 b". I personally date all my batteries... 01/16/18 1, 01/16/18 2, etc.I bought new batteries for my kangertech five6 but 2 of them are 2600 mah, 2 are 2500 mah, and the last one is 2000 mah. Can I use them together or do they need to be the same?
I got them from my local vape shop. Asked for 5 but they only had 4. The 2000 mah was from another local vape shop.@Slaudone where did you buy these batteries? Does not sound like a very reputable supplier in my opinion. Did you order 5 on one type and this is what you received?
I will probably use the single for my vgod pro tube mod.
