The power to weight ratio of this battery make it ideal for single seat race cars, and its military proven vibration resistance make it perfect for hill climb/ rallycross and Lotus 7 inspired track day cars and is also the battery of choice for many of the top one make saloon car championships. Used on Formula Renault cars it will deliver the cranking required on high compression engines up to 3.5 litre and is used in our Grid start and jump start packs and on some of our highly specialised Aviation packs.

The Odyssey Extreme Series available from Powervamp offer both enormous cranking power and deep cycle reserve power, giving you the best of both worlds. Even at very low temperatures, Odyssey Extreme batteries have the power to provide engine cranking pulses in excess of 2250 amps for 5 seconds – double to triple that of equally sized batteries on the market. With the ability to handle 400 charge-discharge cycles, they are as robust as they are reliable. The Odyssey Extreme Series are made with flat plates made of 99.99% pure lead, not lead alloy. This additional purity allows for thinner plates, meaning each battery can hold more at a time, thus providing the plate surface area required for additional power. That's how the Odyssey Extreme batteries produce twice as much power as conventional batteries. Stronger for longer Odyssey Extreme Batteries don't just hold more power, they're also designed to last up to 3 times as long as conventional batteries. Odyssey Extreme Batteries have an 8-12 year design life and a 3-10 year service life. This is achieved using the specialised design features below: Tin Alloy Coated Brass Terminals - ensuring secure, corrosion-free cable connections Robust Intercell Connections – resist vibration and eliminate internal sparking Compressed TPPL Plate Separators – for extreme vibration resistance Pure Lead Plates – extremely thin, pure lead plates provide more power for longer The Odyssey Extreme Series is ideal for just about anything, just about anywhere, including: Emergency Response 4X4 & Off-Road Heavy Duty/Commercial Classic & Vintage Cars Motorcycles & Powersports High Performance & Modified Vehicles Sound and Video Packages Dimensions Length: 184.7mm Width: 79.0mm Height: 191.8mm Weight: 7.0kg
