We listened to our customers and improved and change things as this product evolved. We originally started this project in June 2020. That’s months of learning and evolving, just on this one device. We truly believe this is the very best Sur Ron battery and controller upgrade on the market. we KNOW that other sellers have copied our program (they say to be copied is the greatest compliment), but now that we have pushed the boat even further. Our latest program has now been revised to include MORE power! Improved thermal roll back for motor protection, no problems with up hill starts or roll backwards stalls, no cutting out, extra water proofing, higher grade materials used. Stainless steel battery with extra added powder coating (you scratch it, it still wont rust!!).
The acceleration is phenomenal! Remember when your buying this kit, it was only us and one other business (ERT) that created this product for the Sur Ron. Others have copied, but NO ONE can compete against the quality of these kits.
ASI BAC4000 13500W 431A Phase
So what’s different to the ASI BAC8000? the simple answer is size. The BAC4000 is about 40% smaller so it heats up a bit quicker. So on a very hot day, will throttle back a touch if ridden very hard. The BAC8000 doesn’t get hot at these power levels so is a little more constant. The BAC4000 is set at 13500w and 431A phase.
This controller is now tuned and dedicated for our aftermarket battery @ 72v (max 85V). This is a 72v Kit It carries around twice the amount of energy of a standard battery, so loads more range!! (speed and acceleration kills range, so when comparing to a STD bike, you need to ride like for like)
The controller now features a full working display showing: speed, power, battery charge, date and trip. Set with 5 power levels as default that can be flicked at the touch of a button on the fly (just your thumb, no gloves off or stopping), Can be used like a gearbox to slip up and down the power levels (5 levels set as our default) to suite your terrain and riding style.
The controller comes fully potted and with all leads and looms fitted and waterproofed. The mounts are in place, Made of plastic to include our protective “wings”.
Power levels:
5 Power levels on the fly at simple handlebar push of a button. From super echo to absolutely blistering . We don’t just make this gear, we ride too. Personally in heavy mud and soft slippery conditions (where you don’t want to spin out all the time and actually stay on the bike for the full ride), or blasting around the streets (road legal bikes obviously) and is a good compromise between power and range, mode 3 is enough.
Hit mode 4 for that extra grunt needed for deep sand or on the street, getting a “wiggle On” (mode 4 will also prolong the time before thermal roll back kicks in under very hard use).
Mode 5: “When you absolutely, positively got to kill every motherf***er in the room, accept no substitutes” (quote from Pulp Fiction). Mode 5 should be used and thought of like an after burner from a video game. At full power sustained open throttle, thermal roll back will come in, if used for too long and start to slow the bike down. It should be used when you want extreme bursts, like on a MX track. You don’t need the full open throttle all the time, but when you want it, its there. Like to fire out of a corner or hit that BIG jump – mode 5. Its not designed for full open constant use (that’s mode 4), but you can leave it in this mode, just not full on, all the time – get it?
Please note that running on full power for your type of battery, non stop with a wide open throttle is not a good idea and effectively red lining the motor like on a petrol bike. We strongly recommend that you upgrade to our heavy duty bash guard to increase air flow over the motor, make your frame stiffer and take heavier knocks. Increased air flow over the motor (cooling) will increase reliability and stop thermal roll back kicking in so quick (where power is reduced temporally to help the motor cool). However if you do ride very very hard and get close to overheating the motor, Our new improved thermal roll back will gently cut the power until the motor cools enough to accept full power again. This only tends to happen if your riding full open throttle down a very long straight (road).
Unleash more performance and range with correct gearing. Higher gears (Smaller rear sprocket) does not mean higher top speed. Over labouring the motor with the wrong gearing costs top speed, acceleration and range.
A fast efficient spinning electric motor goes better – simple!.

Controller Feature Set
Displays
Others copy, se we improve and change. The old APT display (as used by everyone else) had a tendency to steam up on a hot day if the bike had been washed with a hose or exposed very heavy rain, So guess what? we went to another display manufacturer and had another display developed just for us. We are the only Sur Ron kit that now uses our dedicated display. Its got our programming and logo on it, so lets see how long before we are copied again (PS, its really good to use)! The display has a choice of 5 power levels, each one can be tuned to your riding style.
Our kit is not compatible with the Eggrider. We dumped that display over a year ago due to too many reliability issues (constant updated needed)
For a real show of power, take a look at this customer set up here on YouTube (we do not endorse road riding and this set up should be used on off road in accordance with legislation: https://www.youtube.com/watch?v=qCP2VqwQyHU
Designed to run the ASI BAC 4000 or 8000, EBMX, KO and Nuclear controllers (any 72v capable controller) up to 400 Amps and use on the Sur Ron Light Bee.
This will not work with the original X Controller.
High Power Sur Ron Battery 20S110P 72v 3024Wh 42Ah Molicell p42A high power 4200 mAh per cell). 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 high output discharge and sustained high drain. Other inferior cells used in cheaper packs simply can’t deliver like these. If you think the cost is high, these batteries have 200 cells that retail in the UK for around £8 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.
Please ALSO note, The Cells are genuine branded 21700 cylindrical cells (not cheaper pouch) and made up into complete battery specially designed by us, built at the factory and final assembly and quality control here in the UK . All warranty work is carried out here with us in the UK.
We simply can’t buy a single battery, Thanks to commercial fees, shipping and taxes the mark-up is minimal!
Charging: First time charging is 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.
Please note, charger is not supplied but can be found here:https://www.electroncycles.co.uk/product-category/batteries/
Self Fitting:
We will include a 13 page illustrated set of instructions. However we do strongly advise for one of our fitters to install. We do make the assumption that if your fitting this kit yourself, you know what you are doing. All kit leaves here tested and working. Think of it like this. You buy a motor from Honda, Suzuki etc and fit yourself. You would not expect Honda to talk you through the fitting. We will not give support outside of Monday – Friday normal business hours.
This is a plug and play system, but we now believe there are at least three slightly different version of the Sur Ron Lightbee motor. This can cause some minor issues. Because of this we now include 1 hour free remote support during our working hours (9 – 5.30 Mon-Friday). We strongly advise that you factor in our working hours when fitting. We will not give support outside these hours. To give remote support you will need either an media phone/note pad and good internet connection.
We do not warranty damage caused from your fitting. Every kit is bench tested before leaving our premises.
We give UK support!!!!
