anybody installed for xtrail ? effect ?
How high the max transient current at say 16V ?

Sorry I lost many of my school theory about capacitance/coulombs for how to convert the charge to AMP(/h) value. Just want to know the amp value from your cap can support to car e-system, compare to the value from battery. I suspect my car battery is weak which causing cold start is weak, and "might" affect my engine performance. So in this case not sure should I change car battery, or install your stuff :-D
At the end, how much now ?

thks. the battery is > 2.5 years old MF type at 55A/H.
Not like cannot start, but compare car to car, mine is slower/weaker a bit in start up, and off course, engine performance also lesser.
Do you think bigger capacity battery(70AH) helps in cold start and overall engine performance ?
May want to try do grounding.

Hi Eric, may I know the best grounding effect is it from alternator, car body or engine body to term -ve ? TQ.

The grounding cable do help a little on engine smoothness !
But too bad, my -ve terminal's nut&screw is "dead lock" type that not allow nut to be un-screw out, therefore I think those ring lug terminal like from your VS cannot be used ! My grounding cable is without ring lug but bare copper wire exposed, but tighten by screw of both points.

HI, but the stock grounding cable is attached to stock terminal lug, which mean if change one, the task is huge cause need to take out the stock cable, and re-install it on new terminal lug ! Jia lat.
Or, I think maybe can cut/saw the ring lug of grounding cable or VS to become Y shape, so that can just slot in this Y to the terminal point, although the so called contact surface a bit less. Btw, the grounding effect is just significant, I can feel it, and if add one more VS, fuuyoh !
