This is a quality 3.7V 18650 rechargeable lithium-ion battery with a 3000mAh capacity and up to 15A discharge - ideal for the UPS HAT, Super Watchdog, micro:Maqueen, KitiBot and any other projects requiring the specific 18650 battery format with plenty of juice in the can!

We only source these batteries from our trusted UK battery supplier due to their careful testing ensuring each cell is EU/UK regulation and RoHS compliant. Each cell has clear polarity marking and comes in its own individual plastic storage tube for added safety and protection.

These 18650 cells are the unprotected type, meaning you'll need to ensure you use them with a device that provides protection such as reverse polarity protection, overcharge/discharge protection, over current protection and short circuit protection. If you're not sure what this means, you shouldn't be buying this battery - safety first!

These cells offer up to 15A continuous discharge. If you need something higher, our 2500mAh 18650 cells offer up to 20A and are usually a little cheaper.
