ASI BAC855 72v BBSHD Controller + Hard Case Triangle 72V 17.5Ah 2600W
UK Stock, No Import tax, No Waiting, No China returns!!!!
Only UK and EU Ground shipping
This is the fastest BBSHD upgrade solution in the world.
Higher Volts, Higher RPM Higher Speed !
This purchase the controller will be set to 72v by default
International orders will be charged additional shipping (we now ship to EU)
This is very latest controller with enhanced feature (see photos)
This is truly plug n play and expect GENUINE speeds of around 45+ MPH
Did you ever wish your BBSHD went substantially faster, pulled harder and you didn’t have to be told you can’t buy the controller you want – shush it’s a secret?
This controller has everything: field weakening (allowing higher rpm), totally plug n play and now with tuneable PAS via our new Electron Display.
Advanced processing and state of the art allows it to compute much faster and much more accurately than the standard Bafang unit (or any modded Bafang controller). Imagine your first media phone in comparison to the latest Iphone/Android device? – Things have moved on and these Canadian devices have not been designed with penny pinching mass market sales like the original. All of this makes your motor pull much harder and release around 15% more speed than a 52v 30A Bafang controller and whopping 100% more power than the standard and go 72v 200% !!!!!!!!! We might add the power is designed to come in without the mechanical snapping lurch of an inferior set up.
These controller have been set up so that it can handle anything from 50A (70 A burst) up to 2600wW depending on voltage (easily within their design). This might mean a little explaining:
We have tested the BBSHD to destruction and on more than one occasion right up to 4500 Watts and learned a few things, real facts and not the odd exception.
Amps create heat, heat weakens the nylon gear and too many watts snap the pinion. So how do we get around this? Simple, know the limits but don’t get too close. Sure these are now nearer the limit, but ridden correctly (let the motor spin and don’t labour in the wrong gear), a reliable ride can still be had. At the lower volts where big amps are needed, we have capped the limit to 2600w @72v but as you increase your volts A ludicrous controller at 50A has 2500Watts, but now add 10 -15% improvement through field weakening!
But here it gets even better, Change your battery and go up to 20s 72 V (any voltage form 10S to 20S, 36V -90 V) and the controller takes it (not a Bafang originated 60 V cap). Your watts have now jumped to a dangerous 4200 watts on a “hot” (fully charged battery at 84 V), so we reduce this limit to a safer 3000W, but still so much powwweeeeer!
Now with working brake and gear sensors.

Battery 72v 17.5Ah:
We normally only sell our own bespoke batteries, but when we found these, we were so impressed that we decided to buy some in and sell them pour selves.
Tough hard ABS cases that are water sealed, LED batter display and quality on/off swatch. There’s another well known manufacturer (low quality) hard case seller out there that simply does do a good enough job (we booted then four years ago)..Our supplier took the case idea from them, went back to the drawing board and decided to o it properly!
PURE Nickle strip
Inn house quality BMS that wont fail.
50 Amps continuous discharge but peaks of 150A!
17.5Ah @ 72V giving 1260 Watt Hours – Brilliant range for a triangle in frame battery!!! (this is 3 times bigger than the standard Bosch Powerline battery.
0.2 mm pure nickle sheet welded.
100 x Panasonic GA 3.5 AH (20s5P) 18650 cells (best in class) 20S5P.

Anderson XT60 Charge
Incudes 4A charger
This battery is suitable for our ASI BAC855 72v system.
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 as above. The charger will display two red lights (charging) after a long period of time (between 1 and 8 hrs – depending on state) the LED charger lights will display red and green. This indicates an initial charge is complete. However, as this is a new battery, not all cells within the battery are balanced (same state of charge as some were higher/lower than others to start with). This is because cells can arrive at the factory in different batches and may have slightly different charges due to time in storage). This is very common and normal. Now please leave the charger connected to the batteries for a further 12 hrs. This allows the internal balancing system (BMS) to balance out all the internal cells. The charge may turn on and off over this period of time. This “Balance charge does not need to be done every time and is recommended every 20+ charges. Leaving the charger plugged in working does not damage the batteries. The charger is designed to stop charging at a preset level and turn on again when this level drops.
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.
* Warranty, due to the nature of use of these devices (off road) warranty is limited to 12 months from date of purchase. Any damage the result of water ingress, alteration, may void warranty. This includes shortening of cables and changing connectors. It is the owners responsibility to proof against water ingress and not use in unacceptable very wet conditions, or use direct water from hose/washers. Any alteration modification to this controller or its subsequent wiring, even cutting the power leads to make shorter will immediately invalidate any warranty. Even battery disconnected, the controller can still maintains current and can be shorted/damaged. The controllers are waterproof, but can still suffer from water damage through the connector and hence are not covered for water damage.
Using high PAS in a high gear under heavy load may cause the controller to overheat (power level 9 in a small rear cog). Gears should be used going uphill or any other heavy load.
Attempting to reprogram the controller may cause damage.
Warranties are not transferable.
We reserve the right to slightly modify or change this product without notice.
