I have the bigger brother Odyssey in my Subaru its still lite but not as lite as the PC680,it has been superb though :up:if ordering one just make sure that you order the MJ version of the Odyssey battery,as they manufacture two versions of each model,the MJ stands for metal jacket meaning it can still be fitted in the engine bay if required as they are designed to take engine heat,saying that though if you are looking to install it in the cab for example under the drivers seat or in the boot the standard version will be fine,metal jacket version's are usually "RED" all over and the normal versions are "RED"with "BLACK" sides,one more thing if buying a PC680 you have to buy the battery terminals separately as they do not come with the battery.SJ.
