Choosing a cell is not only about capacity. Range, power, how often you cycle, charging speed, temperature and available space all affect the right choice. These comparisons are a starting point: to size a system or design a pack, always check the datasheet of the specific model and your actual operating conditions.
Different applications have different needs. That is why we work with several technologies, so we can choose the most efficient, safe and sustainable one for each project.
Our speciality since 2015. A safe, proven chemistry with good energy density and thousands of cycles. We offer one of the widest ranges of lithium iron phosphate cells on the market.
Typical applications: Marine, campervans, solar storage, UPS, electric vehicles
