We listened to our customers and improved and change things as this product evolved. We originally started this project May 2020. That’s years of learning and evolving just on this one device. We truly believe this is the very best Sur Ron 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  we have pushed the boat even further. Our  program revisions adapted to deliver: smoother, relabel, safe and higher 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 metal brackets.

The acceleration is phenomenal, truly AWSOME! 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 BAC8000

This controller can deliver battery types (depending on the map you choose) ranging from the standard untouched Sur Ron battery (we do not recommend this as the performance improvement is negligible),  including a  “Bypassed” Sur Ron battery (reasonable improvement). But is really “Tuned” for our aftermarket  batteries  @ 72v (max 85V). This is predominantly a 72v Kit and not “tuned” for a standard battery.  From testing we believe the safe max working power for the Sur Ron OEM motor is 470A phase and 13.7kW of power. For the KO motors, the limit is set by our batteries (Please see the list at the beginning of this listing).

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. (9 power levels available by simple settings in display for even greater refinement). The advanced features of the display, also allow you the customer to tune each of the power levels: increase or decrease them as you wish.

The controller comes fully potted and with all leads and looms fitted and waterproofed. The mounts are in place, stainless steel and powder coated in black.

Power levels:

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 you follow our install guide: drill holes in your bash guard, remove the restrictive rubber boot and foam padding ( to increase air flow over the motor). 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). 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 laboring the motor with the wrong gearing costs top speed, acceleration and range.

A fast efficient spinning electric motor goes better – simple!.

Our recommendations for a fully equipped 72v system:

For road use:                           10-14 stone rider 52T.           15-17 stone rider 54T.        18+ stone rider plus: 56T

For Off Road/Off Road:       10-14 stone rider 54T.            15-17 stone rider 56T.         18+ stone rider plus: 58T

Pure Off-road/MX Race:      10-14 stone rider 56T.           15-17 stone rider 58T – 60T.     #

Controller Feature Set

  • FOC (Field Oriented Control)
  • improved torque throughout the rev range
  • Higher RPM compared to the stock controller on 60V and especially on 72V
  • Silky smooth throttle control and responsiveness.
  • Improved efficiency due to FOC algorithm, premium internal components within the controller (like the mosfets) which increases efficiency while reducing heat losses
  • Loom
  • Mounting Kit
  • Pre-installed 6AWG phase cables
  • Side panel “Wings”
  • Install Instructions
  • Display with personal power tuning available
  • Both the ASI BAC4000 and ASI BAC8000 use almost the same programming. The ASI  BAC4000 under exceptional hot day and extreme hard use may throttle back and restricted to 431 Phase Amps. the ASI BAC8000 is capable of 850A. The ASI BAC8000 designed for much bigger motors, will not throttle back and will never be stressed.

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 devolved just for us. We are the only Sur Ron kit that now uses our dedicated display. Its got our programing and logo on it, so lets see how long before we are copied again (PS, its really good to use)!

There is no actual need to to reset the display between voltages. However the battery status will show incorrectly if you do not. This is a simple few button press in the settings. We do not recommend the use of percentage for battery life, but use the voltmeter feature: @72v its dead at 58Volts!

The important factor to remember are:

72V battery: full at 83V-84v and empty at 58v. If you have a battery with no BMS  discharge monitoring (only used to balance charge),  you must stop riding your bike at 58V as going below could damage your battery. With the Electron Cycles 72v battery this is not and issue as the BMS will protect  the battery and cut your motor before damage to battery occurs.

On a Sur Ron “Bypassed” Battery. The battery if full at 67V and dead at 48v, However you will not be able to charge your battery with an OEM charger, if you go below 54V. This does not harm the battery but you will need to buy or “Recovery Charger”  if you want to get around 30% more range than a standard SR battery: https://www.electroncycles.co.uk/product/sur-ron-recovery-charger-for-bypass-mod-flat-battery/

On a Sur Ron standard Battery. The battery if full at 67V and empty at 54v, The BMS in battery will stop your battery from draining too far. In reality there is very little gain on running a STD SR battery  with this controller unless it is bypassed.
