If you need a complete battery package with charger and mounting hardware for securing to your bike, this is the place. We carry two lines of lithium battery packs for electric conversions, an eZee flat pack system and select Allcell Naked packs.
The eZee packs have a rigid enclosure with locking on/off key switch and a rail slide that allows them to latch onto custom bike racks and our Grin Tech battery twist anchors. They are available in 36V 9Ah LiFePO4, 36V 14Ah Sony LiMn, and 48V 10Ah Samsung options.
For long range requirements, the 36V and 48V Allcell batteries carry a significant amount of energy to get you 50-100km distances on a single charge. These packs are only contained by heatshrink and lack a rigid enclosure. We have custom mounting hardware designs in the works but until then any number of conventional bicycle trunk bags can suffice just fine.
Please note that large lithium batteries like those used in electric bicycles must be shipped as Class 9 Dangerous Goods as per UN38.3, with special boxes, special packing materials, and of course extra Dangerous Goods fees. The typical hazmat shipping rate within Canada is about $80, to the US is about $120, and overseas is even more.
