This 48V lithium-ion battery is lightweight and delivers a high performance and long running time. The power will not fade in use, so you can work for long periods. After 1000 charges, the battery will still deliver over 85% of its original capacity. Efficient and cost-effective, using this battery will cost just a small fraction of the cost of using the equivalent petrol powered machine. You can use the battery to power multiple tools. There is a smaller capacity battery available (Mountfield MBT4820Li).
