When designing the technical part of my cabin I have also opted for LiFePo battery. The gravymetric weight saving based on the useable energy level is impressive compared to Lead-Acid.

It is am Mastervolt with 110Ah.

Charge controll is being done by a Votronic Tripple wich combines a PV MPP tracker, supplied by two thin film pannels with 200 Wp, alternator charge booster and grid charger.

Since everything is still in the build-up phase I do have very little experience...


I have encountered one mildly annoying draw back of the LiFePo battery: Is seems to have a build in electric fuse. Trying to run my 2 cylinder 600 W 12V - the initial start up current might be well over the rated 50amps - compressor on it,always triggered the fuse... I finally had to draw a 10 or 16? mm2 cable to the starter bat. Grrrreat!

Cheers Volker
