BATTERY and CHARGER, 48V 20Ah 'Maxi', frame mounted

Add glorious reliable range to your system, with our Maxi48 battery, great for overpowered kits of 500w or more.
REV 48V 20Ah Maxi battery, complete with micro XLS charger.

Unlike most others of this type, this battery comes with a top-quality balancing BMS, LG 2170 cells, reliable tabbing & circuitry, key lock and switch and 2 fuses (on output and input), for your piece of mind, and our solid 2 year warranty.  

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.  Or a great way to make a more solid mounting with less effort is using the Triple Bob Clamp (highly recommended)

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.

Beware of cheap batteries!  This battery will last the distance, for many years!
