Hi
I have 6 Panasonic NCR18650B 3.7v 3400mAh 18650 Rechargeable Battery I bought for My project but Never used them as I didn't find charger for these batteries. If anyone interested I can sell these in 5250INR and free shipping.

These batteries can be used in Quadcopters and Airplane or anyother  DIY project

u can make a 6s or 3s battery pack and use it if u have a imax b6 charger

Are these originals ?

how much for single battery??

Yes these are original panasonic
