A battery is a battery is a battery.However I disagree on the fact that if you don't race the car, weight saving is not really important.As you would already know, weight reduction improves acceleration, braking, gets you better handling etc etcI enjoy driving my car spirited from time to time whenever road and traffic condition allows, so I love making my car perform better in all aspects. Making more power is of course what everyone first jumps to, including me, but every car platform has a glass ceiling of bhp/torque before it gets exponantially more expensive (more so if you care about safety/reliability aspects as well).I have hit the glass ceiling for my car, so weight saving comes naturally as the next thing to look at.If seen alone, 23kg might not make significant differences, but if a weight reduction project includes lightweight wheels, swapping to non-rf tyres, carbon fibre bonnet/trunk, lightweight exhaust (which is essentially my plans), you could possibly achieve up to 100kg reduction, which then suddenly becomes very significant.And amongst everything in the list above, RM3k for 23kg savings is probably the most cost efficient. Besides gutting the interior/removing seats of course (which I am not willing to do). Not saying its not a lot of money, RM3k is a lot, but it is the most efficient if one is going down this route.</blockquote>
