These Frame Bag Batteries are a great way to add a battery to an otherwise difficult-to-mount frame.
This is the same bag that is now coming standard with all of our conversion kits. Our customers have been enjoying these battery packs so far!
Our batteries are built using the newer 21700 cells that are rated at 5000mah (5ah) per cell (Panasonic 21700A / BAK N21700CG / Samsung 50E depending on supply). These make for a very energy dense battery pack.
