The EVE C46PH 21Ah is a compact high-power cylindrical LiFePO4 cell designed for applications requiring strong current output, fast charging and reliable low-temperature performance.
It supports 8C maximum continuous discharge and an official 30C pulse discharge rating for 10 seconds, while real-world customer testing has demonstrated burst discharge performance up to 70C.
With an initial ACR of only 0.4±0.1mΩ, maximum continuous charging up to 5C, discharge operation down to -40°C, and long cycle performance, the C46PH is particularly suitable for starting batteries, high-performance motorcycles, motorsport systems and other high-power battery packs.
Its compact Ø46.8 × 146.4mm cylindrical format also makes it an attractive choice for projects where high current capability and installation space are both important.
