I have a slightly used (one season) Genesis EP16 Lightweight Battery. This thing is ridiculously light at only ~10lbs. For reference, an OEM battery for the B5 chassis weighs a whooping 48lbs. Swapping in this battery will shave more than 35lbs off your front end - more than a carbon fiber hood!

Price has been reduced! $70 shipped to the 48 states. Terminals are not included ($10)
