This has been specially designed to get the best balance of performance and range in a down tube battery yet monstrous 80A – diischarge
Maximum watt draw 4000 watts although designed for 3000 motors
This 52v 12.6Ah (fully charged 58v) has significantly more power than any other battery 52V battery and with 80A on tap, massively increase acceleration. With 655Wh 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 BAC855 controller and the CYC X1 Pro motor. Now breaking the boundaries with a new 21700 specific case, we opted for 14S3P configuation with these massivliy poweful and larger 21700 cells capable of 30A each, the very expensive and hugely reliable best on market Molicell P42A, and allowing the extra space to use a large 80 A heavy duty BMS
This is the very best of battery technology with 4A UK charger. 80 Amp Nominal BMS welded to pure nickle 0.2mm sheet. 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 42 cells that retail in the UK for around £8 each! not including: BMS, casing , charger, shipping taxes AND FABRICATION.
This in reality a small battery for such high power. Motors like the CYC x1 pro can kill almost anything if ridden incorrectly. Just like a car or motorbike, full power continuously will speed up breaking things. When riding your bike, allow the motor to spin when in high power mode. Use your low gear (big teeth count on the rear) this will take the load off the motor. This will also give you better range and stop everything from over heating. This battery is designed to handle 80A and higher bursts, but doing so increases the chance of failure, we recomne dthem be used no more than 65A continiuosly. When you want to ride very fast on throttle, set you gear to allow gear and middle to top of cassette to save your chain and let the motor spin. When you want to PAS (pedal), drop the power and use the whole cassette. Your bike wasn’t designed to do both at the same power setting. Riding with electrical sympathy, better for your: battery, for your bike and better of your electrical components.
Because this is such a powerful battery and way beyond the realms of normal, we have had to make some modification. The power cables exit through the rear of the battery and not through the cradle. No cradle in the world can handle this amount of power. The cradle is still used to mount the battery and locks as normal.
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 80A, 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 X1 Pro. 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. Due to 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= H 141 mm * L 368 mm * W 91 mm please allow another 25mm to get on and off cradle
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.
* 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!
Warranties are not transferable.
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.
