Introducing the New 80 Cell Jumbo E-Bike Battery Case

As custom e-bike builds continue getting more powerful, battery builders need larger and more flexible battery enclosures capable of handling serious capacity and high-current systems. That’s why we’re excited to introduce this new 80 cell jumbo battery case designed specifically for advanced lithium battery builds.

This oversized Hailong-style enclosure opens the door for longer range, higher voltage, and higher power e-bike battery configurations while maintaining a clean integrated bike setup.

Built for High-Capacity Battery Builds

Unlike standard battery cases that limit cell count and pack design, this jumbo enclosure can fit up to:

• 80x 21700 lithium-ion cells

This allows builders to create powerful custom battery packs for:

• Long-range commuting
• High-power performance bikes
• Off-road e-bike builds
• Custom DIY battery projects
• High-current systems

The extra internal volume makes this one of the most versatile battery enclosures available for serious builders.

16s5p Configuration

• 52V nominal system
• Supports up to 80A BMS
• Excellent balance of power and range
• Great for high-performance commuter bikes

20s4p Configuration

• 72V nominal system
• Supports up to 80A BMS
• Ideal for extreme performance setups
• Perfect for high-speed e-bike builds

13s6p Configuration

Why Bigger Battery Cases Matter

Many standard e-bike battery enclosures are simply too small for modern high-power builds. Builders are often forced to:

• Use oversized external battery bags
• Split battery packs into multiple enclosures
• Sacrifice range or power output

This jumbo case solves those problems by allowing significantly larger battery packs in a clean downtube-mounted design.
