RIWALL PRO Battery 20V, 4 Ah PRO RAB 420

Battery technology

HDSC technology – the latest technology for electronic power control and protection for charging lithium batteries. The result is not only a precise charging process, where each individual cell in the battery is constantly monitored and recharged according to its current needs, but also unique power management. The battery can optimally adapt to any machine in the Riwall 20V series, always providing maximum performance and making the most of its capacity. Another positive impact of HDSC technology is an increase in battery life, maximum extension of the machine's running time on a single charge, and protection of the battery itself from overload or overheating.

Charge status indicator – simple indication of the battery's charge status using integrated LED diodes. The indicator is part of the battery, not the machine, so you can check the immediate battery capacity without having to insert it into a tool.

Powerful battery cells – high-quality lithium-ion cells, along with smart electronics, deliver the necessary power instantly, even when there's a sudden surge in power demand.

One 20V battery powers everything – there are many systems where one battery is enough for a whole range of tools. However, due to missing or cheap electronics, it often happens that a battery works well with some machines but not with others. This is because there are huge differences in the power draw curves of different types of machines. Thanks to the advanced electronics, the Riwall battery “recognises” which machine it is in and adapts to it perfectly. This means you get the maximum performance and working time from every tool.

Additional information:
The Riwall mower is powered by two 20V batteries. The resulting voltage is 40V, giving the mower plenty of power even in taller grass.

Thanks to cooperation with the German tool manufacturer Scheppach, Riwall 20V batteries can also power more than ten types of Scheppach 20V cordless tools (drills, grinders, saws, planers, impact wrenches, etc.) and vice versa.
