KandyPens 350 mAh Battery Review Bottom Line

The KandyPens 350 mAh Battery is a 510 thread "plug and play" battery that is designed specifically for oil cartridges that require a higher output voltage. It has some advanced features such as variable voltage and sesh mode, but it is still very simple to use. A triple coated lacquer paint and an embossed KandyPens logo makes this battery look sleek and luxurious, and it feels solid- inline with other KP products. Simple, capable, this is definitely one of the best 510 batteries around.
