Our 36v Lithium Batteries are built using the Samsung (SDI-ICR18650-22P) cells.  These batteries were especially selected to power the 36 volt Bafang 8FUN mid drives but will work with most all Ebike motors requiring a 36v source. When comparing or selecting batteries it is very important to know and consider the “C” rating of the battery. See chart below to help make your selection.

Range will vary based on terrain, rider weight, speed, acceleration, wind and other factors.  At 20mph on flat ground with a 170lb rider, you can expect a 25+ mile to 35+ mile range depending on the capacity of battery you choose.  The batteries securely mount to the base and can be locked into place with the included keys.  Batteries can be removed easily without disconnecting any wires to charge indoors or to swap in a fully charged battery for extended ride time.

    I have a down tube mounted pack on my townie style frame. It is also the Samsung 22p 18650 cell based pack. It really quite amazing mounted along with the BBS01 350w 36v kit and a 48t chainring. It manages to hustle my 220 pounds song at 20 miles an hour. Heck it even pushed me at 19 in 30f temps today. I'm thrilled at how well it's doing in a tropical Minnesnowta winter. 12.3 amps squeaks out nearly 25 miles. Not a good idea to run it full throttle for 25 miles, but I did to satisfy my curiosity. The second pack used by my 115 lb wife, who likes a pedal, gets her around all week on assist level 2, on a 5 level setup. I'm happy I decided on the 22p packs. And even more so on the 350w kits.
