Mega Shark e-bike battery. 52v 25AH 50 amps continuous. 13.6 lbs. This is the newest and largest shark case for 21700 battery cells. The Samsung 21700 50G 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 Samsung 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.

Includes battery mounting cradle with 12 cm pigtail.

Features include:

  • Mega Shark includes metal mounts, beefed-up plastic tabs, a thicker case
  • Samsung 50G cells protected in honeycomb internal lattice
  • More flexible mounting with an extra mount slot at the rear of the mount cradle.
  • Mechanical locking key switch for security
  • Push Button 4 LED charge level indicator
  • Installs to Water Bottle eyelets on the downtube (Triple Bob optional)
  • XT-90 Connectors for Power
  • Fits in many frame types
  • Long range  (50–90 miles typical)
  • New Reention mini-XLR stronger, more reliable charge port
  • Size: L=367 mm, W=95 mm, H=156 mm
  • Size inches LWH = 14 1/2" x 3 9/16" x 5 9/16"
  • Weight: 13 lbs 12oz
  • UN38.3 safety certification.
  • 2 amp and 4 amp, 1-5 amp, and  80/90/100%-charge, charger options.

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. 

Here is an article providing information on 52v vs. 48v batteries.

    As someone living in El Salvador, finding a reliable online bike shop with certified batteries was a top priority for me, this battery has been working in perfect condition since day one, after one week of traveling. I requested a change of connectors in the order notes, and they executed it flawlessly, the battery and charger arrived ready to use, with everything done to the highest standard, im extremely happy with my purchase and will definitely shop with them again in the future!

    Customer Feedback:

    I am cycling with a Reactive Adaptations Bomber handcycle. I use this mt bike to ride with other veterans. At present I am working on a 250 mile bike packing route and need more power and longevity from my battery so I upgraded to the Mega Shark. I also purchased a solar blanket to be able to recharge my batteries while in the back country of Idaho using my trike to pack as well as hunt. I have charged my battery with the solar blanket and have charged my Anker Solex 2000 solar generator with the solar blanket and used the solar generator to charge my battery. This has become a great combination for bike packing as well as trips to Moab etc. I have been able to more than double my distance traveled with just the addition of the battery. Using the solar it is now endless.

    I have had a Luna Giant 3,000w for 5 years with over 4,000 miles. The battery died. So I got an Electrify Bike Co. Mega Shark battery. It is fast and powerful. Got good tech support and fast shipping.\nHighly recommend.

    Review Title: Long Lasting

    Customer Rating: 5 out of 5 stars (Excellent)

    Reviewer Name: LeRoy U. (Verified Purchase)

    Review Date: 2023-06-22

    Customer Feedback:

    This is a long lasting battery that can really extend your range, especially if used conservatively. But it can also improve distance when in all-out race mode, as well.\nI am going to eventually get a second and run two Mega Sharks in parallel. The downside is that this battery is 13lb 12oz — almost 1 stone (14 lbs). This can make the bike feel like a small motorcycle. Especially with a parallel battery setup (27 1/2 lbs worth of battery alone).
