52V E-Bike Battery – Samsung 50G Slim Shark Pack (15Ah)
Samsung INR 21700-50G cells (5000mah)
The 52V Slim Shark is specifically designed for riders who need a high-capacity lithium-ion pack without the bulk of a standard ‘Jumbo’ case. This 14s3p configuration is the perfect match for Bafang BBS02 or BBSHD mid-drive kits, as well as various hub motor conversions. Whether you are commuting from Reston to DC on the W&OD trail or tackling weekend hills, the 40A continuous discharge ensures your motor gets the current it needs without the dreaded ‘voltage sag’ found in cheaper, generic battery packs.

Key Features:
- The Samsung 50G Cells are considered industry-standard reliability with 1,000+ cycle life. Your battery will last for years, not months. You’ll thank us later.
- Slim Shark case fits into tight triangles where other batteries won’t, making it compatible with more mountain bike frames. It really is the best of both worlds in terms of power (wattage) and form factor.
- Comes with XT90 Connectors which means high-heat resistant connectors that won’t melt or spark during high-demand uphill climbs.
Optional connector swap or adapter is available upon request.
If a vendor cannot tell you how their batteries are configured, which cells were used for the pack, or what BMS is soldered, please be very cautious supporting these businesses as not all batteries packs are created equal and can be dangerous, especially in an e-bike use case.
Why the 50g for the Slim Shark? We were looking for the right balance, the Samsung 50G was the obvious choice. It isn’t just about the 52V punch; it’s about how this pack handles the heat of a Virginia summer and the repetitive “drain-and-charge” cycles of a daily commute. We’ve personally tested these packs on the steep grades near Rosslyn to ensure they don’t cut out when you need the torque most. We don’t just sell these batteries; we ride them. By choosing this Slim Shark, you’re investing in a pack that was curated by enthusiasts who understand that a reliable commute is non-negotiable. If you’re unsure if this sleek profile will clear your rear shock or water bottle bosses, shoot us a message and we’ll be here to help you get the build right the first time.
