Custom Battery - Molicel P50B

The Molicel P50B is one of the most advanced 21700 cells available, delivering 5000mAh of capacity without compromising performance. Built for high-drain use, it provides strong, consistent power under heavy load while staying cool. With a cycle life rated at twice that of the Molicel P45B, it offers high energy density, long lifespan, and strong output.

All packs are built to withstand the demanding conditions of electric vehicles, using reinforced materials and extra welds for enhanced durability and long-term reliability. Designed for high-performance use, each battery is overbuilt and purposefully engineered to handle the toughest rides without compromise.

Each battery is made to order using authentic grade-A cells and includes a Bluetooth BMS for real-time monitoring. Optional USB charging and a display screen can be added for instant updates on voltage, percentage, and temperature.

Custom builds from 7S to 20S will be built and shipped within 3 weeks of ordering. After your order, we’ll contact you to confirm your enclosure. You may need to measure the usable space in your battery compartment. If your battery needs the BMS to control discharge, build time may be longer.
