I cant be the only one that has devices that use the numbered cells. I have 2 flashlights that run on the 18650 3 that run on 14500 and a cell phone charger that takes 18650sThere isn't. People just don't want to buy the LiPo pack and the appropriate charger since it ends up being a bit more expensive. It's probably for the best since LiPo's are actually kind of unsafe for the average user who isn't taking care when using them. Individual cells have their place for that reason.
now i have a stryfe and a rapid strike that uses them...
i have 0 drones 0 remote control vehicles that use the li-po why should i invest in li-po when i already had the cells...
