Introducing R-eCycle's line of high discharge battery packs made in the US by AmericanElectric. These packs feature genuine Samsung 21700 50S cells, 50-80A BMS and copper bus bars. They are currently available in three configurations:
 
52V, 500Wh, 10Ah, 14S2P, 50A BMS, DP3 case
52V, 1KWh, 20Ah,14S4P, 80A BMS, DP9 case
72V, 1KWh, 15Ah, 20S3P, 80A BMS, 2170-7C case

Not all e-bike battery packs are created equal. There are many cheaper packs available on eBay and Amazon. In many cases, the sellers won't disclose the battery cell type or manufacturing source. R-eCycle uses genuine Samsung, LG and Panasonic batteries because they are manufactured to higher specifications to ensure consistent performance, longevity and reliability. Our packs also use an internal honeycomb structure to securely retain the cells and maintain pack integrity.
 
Each of our packs comes with a mounting bracket to attach to the bike frame, making them easily removable. They include an integrated keyed locking mechanism, an on/off power switch and a LED battery power level indicator. A female XT90 connector provides plug and play connection to CYC Motor kits. 
 
These packs are charged via a 2.1mm DC charging port connector. Battery charges are sold seperately with these packs and available in rates between 2-5A. You can find charging options here:
52V battery charger rated at 58.8V 2A and 4A
72V battery charger rated at 84V 3A and 4A
Grin Satiator programmable, waterproof, variable power level battery charger for 52V or 72V packs available in 58.8V and 84V configurations
 
The Grin Triple Bob Battery Mount (found in Accessories) is highly recommended with the Jumbo Shark Packs for additional strenth and greater flexibility in mounting locations. The Triple Bob is designed to fit the DP-7 & 9 mounting points.
