RIWALL PRO Rotary mower AKU 20V RALM 3820 set (2x4Ah)

The Riwall PRO RALM 3820 set is a mower with a motor powered by two 20 V batteries (40 V) with cell protection during charging. The 4 Ah batteries are charged with two chargers that fully charge them in 90 minutes. Battery technology ensures high performance, easy starting and quiet operation. The cleverly shaped polymer chassis and discharge tunnel ensure efficient grass collection. Ergonomic and foldable handlebars bring comfort during work and easy transport. The central cutting height adjustment in 6 positions and the large basket with plastic top and large handle make it easy to use. The run time is approximately 40 minutes and the batteries are also compatible with other Riwall machines from the 20 V range.

HDSC technology

Riwall 20 V batteries use HDSC technology, which ensures precise charging and optimal power management. This technology monitors each individual battery cell and adapts charging to the current needs. The battery can adapt optimally to any machine in the Riwall 20 V range, providing maximum performance and using its capacity to the maximum. Another positive impact of HDSC technology is to increase battery life, maximise the machine's run time per charge and protect the battery itself from overloading or overheating.

Charge indicator and powerful battery cells

The batteries are equipped with a charge status indicator using integrated LEDs. The indicator is not part of the machine, but the battery, so you can find out the immediate capacity of the battery without having to insert it into the machine. Lithium-ion cells, together with smart electronics, allow the power you need to be supplied instantly, even when there is a sudden power surge.
