Shark Electric Bike 52v 17.5 Ah

High Power Samsung Battery & 4A Charger.

UK Stock

This is the very best of battery technology: 14S5P 52v 17.5Ah (Samsung 35E high 3500 mAh  per cell and) with 4Ah UK charger. 40Amp Nominal BMS and double welded contacts). Designed to fit on down tube utilising water bottle bolts. These are specifically designed for high output discharge and sustained high drain of 30A and burst . 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 £5.50 each! not including: BMS, casing , charger, shipping taxes AND FABRICATION.

These batteries have been designed for the Bafang BBSHD and other electric bike motors that have a rated up to 35 Amp or up to 1800 watt motor.  These will handle all 30A or lower 48/52V applications but have been specifically built for the Bafang BBSHD. These batteries will run a CYC motopr but the power must be set at a max of 1800 watts. we will not warranty a bms failure if used with the CYC mot0r.

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 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.

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 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.
