These 3v Tenergy LiFePO4 batteries are rated at 750mAh each.  Because they are not traditional Li-Ion batteries they do not require circuit protection.  They provide about 3-5 hours of vaping and recharge in about 3 hours.  Tenergy batteries are of much better quality than some of the other 3v batteries we have tested, giving you longer vape time and no noticeable drop off until they are nearly expired.  Rated for up to 1000 recharges, they are the best 6v vaping batteries we have come across.

The Tenergy RCR123A kit comes with two 3v batteries (used in tandem for 6v vaping), a wall and car charger.  Do not charge any other batteries on the chargers, including Tenergy's own 900mAh batteries.  Doing so risks explosion.
