Designed to run on the standard Sur Ron bike as a direct swap in battery, increasing the range by 200%

Swap out your controler  and set it to 8000W continiuos or 12000w burst and with the: ASI BAC2000, ASI BAC4000 or ASI BAC8000 and Nuclear controllers  (any 60v capable controller); have a safe and genuine fast bike that will give heaps of range and fun. The battery is very similar design as its fast brother, but using a differnet cell configurtion and type, we have given this battey a huge range. Perfect for trail riding or long distance commuting.

These are designed to straight into a standard bike with X controller or for bikes that are set at 8000W. They can go much higher for peaks of up to 12,000 watts (the Sur Ron motor is manufacturer rated at 10,000 for 1 minute).

If this battery is to be used by a third party controller, the controller can not be set above 8000 watts continous.

This will work perfectly with the original X Controller but still only taking 4-5000 watts (you need a bigger controller for more power).

High Power Sur Ron Battery 16S13P 60v  3780Wh 63Ah Panasonic  21700 cell (4800 mAh  per cell),  with ANT bluetooth BMS (works on IOS and Android) designed to fit inside the Sur Ron battery compartment utilizing the existing battery tray. The Cells are genuine branded cells specifically designed for large capaity discharge and reliability. Other inferior cells used in cheaper packs simply can’t deliver like these. If you think the cost is high, these batteries have 208 cells that retail in the UK for around £5 each! not including: BMS, fabrication and shipping taxes.

The whole battery is fitted in  hand made stainless steel case designed to handle those inevitable and hopefully not painful “Offs” with hard off road rides and giving masses more protection. The casing is powder coated inside and out.

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  to IP67 (jet washing and 1m submersion). 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!
No new charger require, just use your Sur Ron charger!!!!!
From our tests, not all Sur Ron frames are exactly the same. Sur Ron recently seem to have let their quality control down a bit. On our mark two prototype (pre releases) we suddenly found that our case did not fit in the 4th bike we tested it in , Sur Ron hand not cleaned the battery compartment frame welds. We then went back to the drawing board and re-deisnged the case.
The new and for sale case has flitted all 4 test bikes. Its a snug and tight fit to maximize the cell capacity and keep the battery as low as possible. It is very slightly possible that there is anther bike out there with poor welds. In this case there is a very  small possibility that your bike welds will need cleaning up with a dremmel/grinder, although with this latest design we have not found this in over 50 installs. This is a simple job and causes no damage to the bike. I would like to make the point clear that we do not expect this to be needed  by 99.9% of our customers the battery should slot straight in.

Please ALSO note, these are genuine new cells and made up into 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 battery to the bike and to avoid a spark. Turn the red trip switch on the bike to off.

Charging: First time charging is VERY important. Always connect the charger to the battery with the charger powered up from the mains. This will stop a “Connection Spark”. The battery needs a “Balance Charge” on first charge. Please charge for 12 hours first time.

* 6 Month Warranty is for manufacturing defaults and does not cover miss use or accidental damage. These units are extremely strong and robust and will not let you down unless abused. We undertake warranties here in the UK. We take the pain!

Please note, Lithium batteries are considered hazardous and due care and attention should be taken. Although these cells are in wide use, and professionally manufactured in a purpose built factory; because of the power of the battery, we strongly recommend that precautions are taken. We do not recommend charging inside the family home and charging should be supervised. We take no responsibility for misuse. These batteries are thoroughly tested (full discharge and charge cycles at the manufacturing stage and also pre-delivery). These are not DIY or amateur built devices.
