The Cell That Changed Everything: Molicel P42A
This year marks the 6-year anniversary of the groundbreaking Molicel P42A — the first power cell ever introduced in a true winter-ready eBike battery pack back in 2020.
When Bicycle Motor Works unveiled the P42A in our cold-weather optimized builds, it set a new industry benchmark:
✔ Exceptional high-current output
✔ Superior thermal stability
✔ Consistent performance in freezing temperatures
✔ Long cycle life under heavy loads
At the time, no other cell could match its real-world performance in harsh winter conditions. The P42A didn’t just raise the bar — it redefined what riders should expect from a premium eBike battery.
This legendary formula became the foundation for what we now call winter-ready battery technology — inspiring manufacturers and engineers across the industry to follow its lead.
Evolution of Power: Enter the Ampace JP50
Innovation never stops here. While many cells attempted to replicate the success of the P42A, only a few truly came close.
Now, we’re proud to introduce the next contender in high-performance cells:
🔋 Ampace JP50
The Ampace JP50 represents the next evolution in battery cell technology:
• High capacity
• Strong current handling
• Excellent thermal management
• Designed for demanding applications
Built to rival the P42A, the JP50 delivers exceptional power while maintaining reliability in real-world riding conditions — including cold climates where most batteries struggle.
It’s not just a new release - it’s the next chapter in winter-ready performance.
