Lightweight Battery Options

[jonnowocky]

Stock battery in my car is pretty shot and will no longer hold a charge for more than a day, so time for a replacement.

That said, it seems daft to not take advantage of the weight that could be saved with a LiPo (12kg saving potentially).

I've been linked to this thread before - https://www.renaultalpine.co.uk/viewtopic.php?t=10... - where the OP mainly has issues because the smart-alternator doesn't detect the LiPo voltage as low enough to kick in. However, this can be rectified by unplugging the Start-Stop system plug from the negative terminal. Doing so throws an alert on start up, but you can just clear OK.
Because of the amount of times the OP says DONT DO IT all over his posts before he finds the solution, I have a feeling this thread put a lot of casual-google-ing owners off.

There's an Italian owner on youtube who overcame the issue with the same solution (LiteBlox LB20XX - very expensive battery).

First thread owner fitted a Lithiumax: https://www.lithiumax.co.uk/shop (more reasonable although the specific model he has is on pre-order and there was no answer when I emailed about it), and someone else in the thread stated they fitted 'the largest Shorai' - but that's a bit vague

I'm happy to fit a quick charging harness and connect to a LiPo trickle charger when parked, this was a matter of course for every other sports car I've owned, so it's not a bother.

Is anyone on here running a LiPo with their A110? Can anyone offer me any advice, specifically on requirements or links to ones that may be suitable?

try braille. i don't which one fits though

I think you can just drop the voltage on the sensor by an diode inline meaning the alternator does not shut off too soon and 14v is delivered for longer. A german lithium battery maker sells a ridiculously expensive black box to do that - only purchasable with their batteries.
