Bro, one of your area in Danau Kota rite? Is it possible if i just deliver it to you and collect the item on the same day? I live in Taman Seri Rampai, near your place. My battery is 4400mAH rating 11.1V ftec model year 2006 i think. Now only last around 1 1/2 hour. If i use 4800mAH how long it can survive?
