AKU FAST POWER 20V

The heart of AKU technology is always a Lithium-Ion battery in 2 Ah / 4 Ah variants. It is not necessary to buy a special battery for each machine, but you only need one, and here you can use it for any machine from our FAST POWER 20V advice. 

Switch it from one machine to another quickly and easily (with a click) and you can continue working. Just press a button and it goes! Today's AKU technology can offer the performance and dynamics of petrol machines! This is guaranteed by the fact that the machines such as garden mowers or brushcutters, the full power of two batteries is used at the same time. For smaller machines such as drills or blowers, only 1 battery is used.

The active accumulator management system continuously monitors and regulates accumulator parameters via a built-in microprocessor. It monitors the factors affecting safety, but also every single cell whose usage it controls. This ensures the highest safety, optimal performance, high operability and maximum service life of Fieldmann accumulators.

Overvoltage, overheating, self-discharge, deep discharge, or memory effect... The electronics recognize these influences in time and actively intervene against them. This prevents damage to the accumulator. Fieldmann accumulators are manufactured using high-quality components. Lithium-ion cells from internationally recognized manufacturers ensure an immediate supply of energy, longer accumulator life per charge and extend its overall service life.
