Mega Shark e-bike battery. 52v 25AH 50 amps continuous. This is the newest and largest shark case for 21700 battery cells. The Samsung 21700 50 G cells are mounted within a structurally sound honeycomb lattice. The charge port is the reliable mini 3-pin connector, including an on/off switch. This battery is large enough that it is a rare full-suspension bike that will take it, but it is an excellent high-power, long-range option for most hard-tails.

The Shark style is popular because it looks great. ​52V 25AH e-bike down-tube battery with high capacity Samsung 50G cells and a whopping 50 amps output. Removable battery locks to the down tube for security. This battery packs 1300 watt-hours into a tight and attractive package. That is equivalent to two Bosch or Yamaha batteries for less than half the price. The Mega Shark is the most recent addition to the super rugged and proven Shark family of e-bike batteries. They all share the same mount cradle, so you use different sizes on the same bike.

The cells in this battery are high-quality Samsung 50G high-capacity 5000mah cells. We only use grade-A certified genuine Panasonic/LG/Samsung/Molicel cells.

Comes standard with an Amphenol XT90S anti-spark connector. If you want Andersons, we can do that. Just request it in the notes on the checkout page.

More info about Electrify Bike 52v batteries:

Batteries from Electrify Bike Company utilize the latest 21700 cell technology from the leading brands making safe Lithium-ion cells.  The cells we use are all top-of-the-line high-capacity/high-power cells from Samsung, Panasonic, Molicel, and LG.  You won't find batteries of the same size with higher capacity because we use the highest capacity cells available in all our batteries. 

The cells are more expensive but worth it in performance and peace of mind.  Using high-quality cells, BMS, and build quality, ensures that our batteries are as safe as possible. We still use 18650 cells in our low-profile Super Shark battery to keep it as low-profile as possible to fit in more frames.

All our 52v batteries except the Super Shark can deliver an astounding 50 amps of continuous power.  That is over 2500 watts!  Very few motors use anywhere near that power, which means the battery will run cooler and last much longer than a battery rated at or near the same power as the motor.

52v batteries are the most popular batteries we sell. They are often the best choice for 48v motors, including batteries for Bafang BBSHD, BBS02 48v motors, and Tongsheng TSDZ2 48v motors.  They are also the most popular battery for CYC Photon, Stealth, and X1 Pro mid-drive motors.
