⚡ 72V 12.6AH Molicel P42A Bluetooth eBike Battery Collection – Featuring 100 Balance Active BMS
Smart. Powerful. Connected. Built in the USA by Bicycle Motor Works.
 
🔋 The Next Generation of Smart eBike Batteries
Introducing the 72V Bluetooth Battery Collection, proudly built by Bicycle Motor Works – a family-owned U.S. manufacturer since 2014.

Every pack is designed for high-current performance, long-range riding, and advanced monitoring through the 100 Balance Active Balance BMS, now standard across our premium lineup.
Unlike typical battery management systems, the 100 Balance BMS delivers real-time Bluetooth connectivity and active balancing technology for unmatched precision, safety, and control.
 
📱 100 Balance – Active Balance Bluetooth BMS Technology
Monitor your eBike battery directly from your smartphone with the free 100 Balance app.
View real-time metrics such as:
Voltage
Current
Temperature
State of charge (SOC)
💡 Active balance technology keeps your battery cells evenly balanced — even if not charged to 100%. This extends battery life, optimizes performance, and ensures consistent power delivery under heavy load.

⚙️ Ampace JP40 – Advanced Lithium-Ion Technology
 
The Ampace JP40 21700 cell represents a new frontier in lithium performance.
Key Advantages:
⚡ Highest performing 21700 cell by discharge rate
❄️ Cold-weather capable – no capacity loss down to -20°C (-4°F)
🔩 Tabless design supports 140A peak bursts (5 seconds per cell)
🔥 Outperforms Molicel P42A, P45B, and P50B in energy and thermal control
🧪 100-cycle stress test (30A continuous, 5A charge) showed only 2% capacity loss
This makes the JP40 ideal for CYC Photon, BBSHD Ludicrous, and BAC ASI setups that demand both current and endurance.
 
🧠 Construction & Safety
Each 72V pack is precision-built for performance, protection, and longevity:
Solid nickel and copper busbars for low resistance
Tight internal structure improves heat dissipation
BMS temperature protection for thermal stability
Each cell and series is tested before assembly
Smart balancing for even voltage and optimized runtime
Every pack is hand-assembled and tested in Bethlehem, PA, using only certified genuine 21700 cells.
