DIY: Voltphreaks Lithium Battery installation into M3 E92

Hello, i'm from Barcelona (spain) and i decided to install a lightweight battery into my M3. That's why i contacted with Tony from VOLTPHREAKS (www.voltphreaks.com). I chose to install the VPH900 Lithium Battery.

I'm going to describe how i did the installation of this battery into my e92 M3 with a few pictures:



When i recived the battery with aluminium SAE terminals.

Battery comparision: 26 kg against 3 kg



I did two small holes to install a plastic bridles



Velcro at the bottom of the battery to avoid sliding.



Velcro in the battery hole and also you can see the small holes.



Voltphreaks Battery, i installed a rope in one side that i tightened with a plastic bridles in the other side.

The battery is amazing and i haven't had any problems. The battery is very well fixed with this installation.

In voltphreaks website you can find all the battery characteristics.

Ahh one more thing i registered the battery like a 40ah_agm battery!!

I wish this thread can help someone.

Regards!!!
