So after going through a new battery every year i decided to try some new to atvs battery technology. i shopped around for the one i could get at a lower price and not made in china. i bought an alien motion battery and i believe it is made by ballistic evo battery manufacture bc i held them side by sand and they were almost identical. different colors and different lettering, both had the same warrant, and both were made in the states. im just posting some side by side pics incase anyone looks into one of these batteries. this new battery is smaller and lighter so it can be mounted differently but it also came with foam to make up for the size difference and fit snuggly in the oem box. only thing i did was remove some of the oem padding inside the battery box so it would fit. i was more concern with more cranking amps, more than double than stock, than weight savings but the stock battery weighs just under 6lbs and this battery with the sponge padding weighs less than 2 lbs. so the savings are there.
