These have a conventionally shaped lipo cell, same capacity, 500mA

Today I was given these by a friend, slightly fatter square body, these have a very useful 1500mAh cell,
two of these would power a transmitter for a very long time!

What a great idea from Phil, one of many, immediately after reading I phoned up a relative who vapes and next day acquired two vapes and four single cell chargers!
I tapped off the vape ends and removed the battery from each and found they are li-ion 2200 milliamps each. I charged them up individually using the single cell charger that came with them having altered and soldered on wires to the battery tabs. All went well so I decided to make up a 2S pack for my next conversion a Futaba M 4 channel, I’ll send photos when finished as slightly different from the norm. I digress the 2S has worked out very well so now I too will be pestering vaping persons for their offcasts.
