The stainless steel battery box is extremely light and gives your BMW a clear view. It is mounted directly under the gearbox and thus lowers the centre of gravity even further. A clear view through the frame triangle gives the BMW a wiry look. The battery box is made to hold our HJP14 and HJP18 lithium-ion batteries, or for vehicles with more extensive electrical equipment, HJTX20. All batteries do their job without any problems, even with high compaction. The batteries have a weight of 1000g, respectively 1100g. The weight saving is more than 10 kg! A lithium ion battery can withstand six times as many charge cycles as a conventional battery. The self-discharge rate is only 5 percent per month. In the long run a worthwhile purchase.

Important: The battery box can only be mounted if there is no exhaust under the gearbox, i.e. no connecting pipe or pre-silencer. This is usually the case with 2-2 system. We offer such systems for all BMW 2-Valve models.
Installation tip: We continue to use the original plus cable for our conversion. We lay this from the starter through the upper engine cover, through the exhaust filter box (or alternatively accessory starter hood) at the rear past the transmission to the "underengine battery box".
For the -ground we use a new cable in 95mm length. This we screw between the negative pole of the battery and the rear gearbox cover.
