The battery says NCR18650B Li-ion MG12210 on it, if this is any help. Oh, and it's a 3400, not 3600.
Your mod requires a
high drain battery (IMR or IMR/hybrid).
THe NCR18650B 3400mah battery is NOT a high drain battery, and should NOT be used in your mod. This battery was designed for flashlights, and not for use in a mod.
Your mod requires a battery with a
minimum of 12 amps continuous discharge, the NCR18650B only has 6 amps continuous.
