This is a Plug n Play system. The fitting is simple through the existing BB hole. The 750C display give you the options to set how many PAS levels you require 1-3, 1-5 or 1-9 and is adjustable on the fly. Throttle is still instant in all levels, but power is affected by the level you choose.

Please ensure your battery can handle this amount of power. You can use a lower powered (amps) battery but at a lower power level setting.

This has been specially designed  to get the best balance of performance and range in a down tube battery yet monstrous  65A continuous discharge.

This 52v 15Ah (fully charged 58v) has significantly more power than any other battery 52V battery and with 65A on tap, massively increase acceleration. With 780 Wh riding in the lower PAS range will still give massive range.

We wanted to provide a battery that allows balance for a bike and give as many amps possible for our incredible ASI BAC 800 controller and the soon to market CYC X1 Pro motor. Yet with a maximum cell amount of 70 in a case, we opted for 14S 5P (70 cells) and the very expensive and hugely reliable Sony VTC6 to deliver (even the Samsung 30Q could not deliver this amount of performance). There is no other cell on the market that can safely deliver these figures.

Very High Power Sony VTC6 Battery & 2A Charger. UK Stock This is the very best of battery technology with 3Ah UK charger. 60 Amp Nominal BMS and triple welded pure nickle contacts).This is the highest UK output available down tube type battery on the market, designed to fit on down tube utilizing water bottle bolts. These are 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 70 cells that retail in the UK for around £8 each! not including: BMS, casing , charger, shipping taxes AND FABRICATION.


The batteries still mount as usual on the at the  water bottle bolts and can be easily detached. However, because of the massive discharge amps, the battery cables exit direct out of the battery case (at rear) and not through the cradle. This means that it will be necessary to unplug the XT90 plug when detaching battery.

We do not recommend these batteries for power output above 65A, these will handle all 65A or lower  where a controller has a 48-90V applications but have been specifically built for the Bafang BBSHD ASI BAC uparade and CYC X1Pro. They have XT90 connectors and are “plug and Play”

Like any device, running it constantly at maximum could lead to failure. Dont ride open throttle non stop!!


Please ALSO note, these are genuine new cells and made up into complete battery specially to order for me at the factory. I simply can’t buy a single battery, I have to agree to a production run of at least 30 batteries. Thanks to Ebay + Paypal fees, the markup is minimal! Not all down tubes are the same and some slight modification maybe necessary to the mounting plate of the battery. You tube has an abundance of “How To” videos.

Space required, please see photo= 380mm * 120mm * 90mm)

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.
