The PowerChamp RX (Japanese: パワーチャンプRX, Pawāchanpu Āruekkusu) is the Alkaline battery produced by FDK Corporation, the subsidiary company of Fujitsu and released by Tamiya on November 28, 2020

Based on Fujitsu's own Premium S batteries, it is the 11th generation PowerChamp batteries specifically made for Mini 4WD races.

General info[]

On the outside, the PowerChamp RX's battery's body is dominated by the white color, with black highlight that has the chequered flag pattern. It has a gold-plated 'PowerChamp' label with a large red 'RX' label below. It has the silver terminal buttons.

As it is based on the Fujitsu Premium S Alkaline batteries, numerous features were carried over to the PowerChamp RX. The newly-improved anode gel composite material increases its overall performance by 10 percent on average, and also improved its long-term storage by 10 percent. Also new to the battery is the current pickup (also known as collector pin) that is coated with special plated material to reduces gassing inside the batteries and thus prevents battery leakage.

Being made specifically for Mini 4WD racing, the battery's casing has been improved upon and is able to withstand even the higher impact, which in turn also increased a Mini 4WD car's rigidity.

As it is a Alkaline battery, it is heavier than NeoChamp battery and is not cost effective due to being a non-rechargeable battery.
