72v 12Ah 864watts Jumbo Down Tube Battery. Sony VTC6 Cells 65Amps 4A Charger

72v 12Ah 864 watts Jumbo Down Tube Battery. Sony VTC6 Cells. 65Amp Nominal, water proof quality BMS designed for motors and at their best upto 65A. Made with 0.2mm pure nickel sheet welded battery with cell holders.This is the highest Amp hours UK available down tube type battery on the market, designed to fit on down tube utilizing water bottle bolts (we advise the addition of  Alfatex by Velcro straps) These cells are the “king” of 18650 cells are Branded 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 80 cells that retail in the UK for around £5 each! not including: BMS, casing , charger, shipping taxes AND FABRICATION. The fabrication in these batteries is much more labor intensive than our other down tube batteries and use much higher and more expensive components (thicker and  heavier nickle sheet and higher power BMS)

We do not recommend these batteries for power output above 65A,

This in reality a small battery for such high power 20S4P. 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 65 A and higher bursts, but doing so increases the chance of failure. 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 yo better for your bike and better of your electrical components.

 

All down tube battery cradles can only handle 30 A  if the power is passing through the battery case puns. For  that reason we take a direct exit from  the back of the battery direct with an XT90 connector To handle up to 90A

Please ALSO note, these are genuine new cells and made up into complete battery specially by us. Thanks to Paypal fees, shipping and taxes 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. (Due to changing world shipping, we are now also making batteries here in the UK

We do not connect the USB port as we have found that with our wet UK weather, can cause reliability issues.

We recommend the purchase of Alfatex velcro 30cm * 3cm (avaialabe on Ebay) for additional support.

Charging: First time charging is VERY important. Always connect the charger to the battery with the battery turned on and the charger  turned on from the mains. This will stop/reduce 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 over 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!

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.

4A 72v Charger included.
