Batteria leggera per auto da corsa/pista 12V 24AH ~7KG - testata con e46 M3 - Nuova
In that case this 24AH cell should be used instead of the 18AH I normally use. The weight difference is circa 1.1KG. Battery Capacity 24AH. The car is an e46 M3, which has a 3.2L Straight six. It has no fan or stereo for example.
