Varley Red TopTM Racing Batteries for circuit and rally cars

The Varley Red Top Motorsport Battery Range from DMS technologies has been the PREMIER choice for the professional and club racing driver for some 60 years and the batteries have evolved over time to meet the changing demands of both motor racing or rally disciplines.

British Microlight Aircraft Association (BMAA) approves Varley Lithium batteries

The Varley Lithium Li-3, Li-5 and Li-16 have all received approval from the British Microlight Aircraft Association (BMAA) - see here for a link to the approval document.

The Varley Lithium Li-5 receives LAA approval

Following a meeting with technical staff at the Light Aircraft Association (LAA) we carried out some light aircraft specific tests over & above the those required for UN 38.3.  Following the submission of our test report, the LAA were happy to approve the Varley Lithium Li-5 battery - subject of course to installation considerations. 

The Editor of the LAA Magazine, Brian Hope,  had previously visited our premises to find out a bit about us and our batteries. Following his visit he wrote an article for his members that appeared in the August 2015 edition of the LAA Magazine - read the article here.

The Varley Lithium Li-5 proving successful in Formula Ford 1600

Cliff Dempsey Racing ran the Li-5 in both their cars at the Walter Hayes Trophy, Silverstone.  Running 2nd in the Final, James Raven, who recorded the fastest lap, had an unfortunate "off" robbing him of a certain podium.  The second car crossed the line in 2nd place but was eliminated on a technicality.  Ben Norton, Wiltshire College, also running an Li-5, was prevented from progressing into the final having been tagged and losing a wheel.

Following the introduction of the Li-16 we have now added a further two the Li-5 (5.5Ah) and Li-3 (2.4Ah) motorsport batteries.  These batteries fully conform to the UN Recommendations for the Transportation of Dangerous Goods - click here for the latest version.  The Li-5 has a similar cranking performance to the Varley Red Top 15, is smaller than the Varley Red Top 8 and weighs only 1.1kg.  The Li-3 is ideal for motorbike engines up to 600cc.  Click here to go to the Varley Lithium™ page for information about the Li-3, Li-5 & Li-16 racing batteries.

This latest Lithium Ferrous Phosphate (LFP)  LiFePO4 battery joins the Li-16 which is the same size as the Varley Red Top 15 but with the cranking performance of a Varley Red Top 30 - and weighs only 3.2kg.  We also offer two lithium chargers.  Click here for more details of the battery and chargers.

The 2014 season  again proved successful for Varley Red Top users in a wide range of motorsport racing series from single seaters, through Touring Cars and Saloons to GT racing and LMS.  Our batteries are used by many teams so it was hardly a surprise when last year at Melbourne Ted Kravitz came across a crate during his Ted's Notebook session after the race, check this short video clip.:   The BTCC continues to be strong and looks to going right to the wire at Brands Hatch in October. Easter saw a successful second running of the Thruxton Easter Revival featuring many historic series including Historic F2/F5000 and Super Tourers, and supported by Varley Red Top.  We are again supporting the British Hillclimb Championship won last year by Scott Moran.

To ensure you receive the best operating life and performance from your battery we supply a range of chargers, battery mounting brackets and engine start powerpacks specifically designed to meet the demands of all levels of motorsport.  Please read the Battery Care section in our Downloads section (click here).


Our Varley Red Top branded product range is supported by unparalleled technical and after-sales teams through our motorsport-specialist distributors and our specialist staff at DMS technologies.

In addition to working with manufacturers, teams and distributors, we are proud of our relationships with many of the UK’s University Formula Student teams, where we assist the students with help and advice concerning their battery installation.
