The main battery to controller connectors we use are the same type as used by Sur Ron to keep everything compatible. This allows you to swap your standard battery back should you wish.
Battery is in a super tough hand built stainless steel case designed to keep your battery safe in an accident and waterproof  except immersion or direct jet washing at the cable exits. Designed to fit straight into the bike and maximize the whole battery compartment (the hatch bolts need swapping  out with longer bolts that we supply – 2 minutes and simple). No movement- no rattles!

Please ALSO note, these are genuine new grade A cells and made up into the  complete battery, specially designed by us, built at our oversees  factory or here in the UK by our dedicated battery builders. We simply can’t buy a single battery, Thanks to Paypal fees, shipping and taxes the markup is minimal!

When connecting the Sur Ron Battery to the bike and to avoid a spark. Turn the red trip switch on the bike to off. Connect to bike, turn trip back on. Connect second connector.

This Sur Ron Battery are taller than normal, so we include a rear spacer for the battery compartmnet lid and new catch. The height of the battery makes it difficult to install and remove the battery and may need the spacer removed when taking out of the bike. We recomend leavingthe battery in the bike. Higher seat riser, really make the battery blend in. We sell the following to suit the new battery:

Sur Ron Seat Lift Kit Aluminium Black (great for tall riders and tall batteries)
