36v 8Ah Thunder Battery


Designed for use with any 250w motor & controller set-ups, the 36v REV Thunder battery can be used as a primary or secondary battery for any 250w kit or bike, or a replacement battery on any 36v 250w factory e-bike (space permitting).

The battery is lockable for security, and simple to unlock and remove from the bike for easy charging. This battery does NOT have an on/off switch or independent battery gauge.



Frame-mounting batteries are designed to be fitted in the diamond or triangle of the bike frame, which provides central and low positioning, for better balance on the bike.

The bracket is normally attached to the existing water-bottle mounts found on most bikes. These batteries can also be mounted on top of a rear rack if desired, or in the basket of a tricycle. Or, Rivnuts can be inserted on the bike frame, to mount these batteries in other positions, for example on the top tube (eg BMX), below the down tube (eg, maybe dual sus MTB), or anywhere else on a recumbent, tricycle, scooter, etc.
