52V E-Bike Battery – Sanyo NCR Triangle (28Ah)

Sanyo NCR 18650 GA cells (3500mAh)

We categorize this as a high-energy density solution. While the 72V triangle pack is generally purchased for power and speed, this 52V 28Ah monster is all about “Range.” At nearly 1.5kWh (1456Wh), this is for the rider who wants to go 50+ miles without even thinking about their charger.

Key Features:

• With 3500mAh per cell, the Sanyo NCR18650GA “ultra-capacity” cells are among the highest-capacity 18650 cells ever produced by a tier-one manufacturer. This 8-parallel configuration creates a massive 28Ah reservoir, offering the kind of “all-day range” that standard shark packs simply cannot match.

• A battery this heavy needs a serious home. Our rigid, molded triangle case protects your investment from frame vibrations and road debris. The integrated mounting channels allow the nine heavy-duty hook-and-loop fasteners to “lock” the battery into your frame’s geometry for a rattle-free ride.

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.
