So I've been driving with my LI dual (Gen 8) installed for around 6 months now and have been very happy with the performance, however this winter I've had some issues with the electrical system in my vehicle (06' BMW 330i). I've had several issues with the car since I purchased it BMW "pre certified" a little over a year ago (thank god for warranty). The problem I've been having most recently is frequent battery drain. Now, yes this does have something to do with the stupid climate a live in, with temperatures dropping sub -30 in the winter (-22F for the majority of the users on this forum). I came back from Mexico a little over a month ago to find my battery had completely drained and the cells had been damaged beyond rechargeable repair (this more than likely due solely to cold weather and the vehicle sitting outside during our trip). I had BMW put in a new battery (expensive, like everything else with BMW) and drive off. No issues for around a month and now my battery is draining, even though I garage park the vehicle and drive it daily, new alternator was put in a couple of months ago. I have yet to tell the service center of my LI's, for obvious reasons and they're now saying that the battery drain is due to "too short of commutes, under 5KM" and that the battery doesn't have enough time to recover from BMW's "highly advanced electronic system" WTF? Pretty ridiculous, I know.
Does anyone know how much of a current these things draw from your battery on a cold start and/or any possible implications with LI and battery drain in my weather conditions? I now shut off LI and turn on once I've had my vehicle running for a few minutes, just to be safe. I also have a hard wired V1, which I doubt has anything to do with the issue, unless due to faulty install. Other than the V1 and LI, the vehicle is completely stock.
I've been searching around and haven't found anything on this issue. Could be far fetched, but trying to rule out all possibilities here.
