Description

Need an 18650 rechargeable lithium-ion battery for your project? This is a quality 3.7V 18650 rechargeable lithium-ion battery with a 2500mAh capacity and up to 20A discharge - ideal for the UPS HATSuper Watchdog, micro:MaqueenKitiBot and any other projects requiring the specific 18650 battery format.

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 2500mAh capacity - if you need more juice in the can, check out our 3000mAh 18650 cells (which come with a lower discharge rate of 15A max)
