Shark Electric Bike 52v 17.5 Ah
High Power Panasonic Battery & 5A Charger. UK Stock
This is the very best of battery technology: 14S5P 52v 17.5Ah (Samsung 35E high 3500 mAh per cell and) with 5Ah UK charger. 45Amp 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. 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 2000 watt motor. These will handle all 35A or lower 48/52V applications but have been specifically built for the Bafang BBSHD.
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.
Discounted when bought as a complete kit with BBSHD.
Tips on riding:
The motor is not human and makes your bike a hybrid.
Motors like to spin fast, use less power and not over heat and most of all use less electricity!
A 9 speed bike for example.
The whole range of gears can be used with your legs only – no surprise.
If you want maximum range use very low PAS 1-3 and any gear you want to let your legs assist.
Do not use high PAS in small rear cogs, you will kill your range! (your legs are not assisting).
Generally speaking, your cadence is much lower than the BBSHD’s possible 160 rpm. If you ghost pedaling at 30 mph in the 11T rear cog you are doing nothing to help the motor, BUT the motor actually wants to go to about 50 mph when it cant, because of resistance (tyres, road surface , Air etc) – you can use a cadence calculator online to check the speed with your gearing. When the motor can not achieve its ideal speed in a high PAS setting, it dumps loads of “Phase Amps” amps that are wasted producing heat as they cant be turned into motion and make the motor turn faster, they have saturated the motor.
As test, ride you bike flat out without the motor and see what your top speed is . This is he maximum speed will be the speed that you no longer assist the motor.
This is a general ism, as some very fit riders can achieve higher speeds in higher pas without over heating as they have a much higher spin rate, are lighter and powerful enough to push big gears ( do these people really need a an ebike?)
Now using throttle only, find your top speed using the gears. You will notice the smallest or highest gear does not give the top speed, but it will use the most amount of electricity. Go down a couple of gears (bigger rear cog) and the speed will not significantly drop, but your power consumption will – gives you more range!
So for range use the small PAS and any gear you like as your legs are helping and the motor is not trying to achieve to unobtainable top speed.
For top speed use the throttle only and use the best gear, not necessarily the smallest rear cogs.
I use a 42T front. I PAS only in level 2, but throttle for top speed with a 16 or 15 rear maybe ( i check my speed against power consumption).
If im really lazy, I leave it in 16 rear (its flat where I live), use PAS 2 to get to 10 mph (helps the motor ) then use throttle only to 30+mph. This saves the motor, saves the drive train and im lazy. If I want to go miles, I use all my gears and PAS 2 only and the throttle up a hill in a big rear gear with it spinning freely.
At 30 mph throttle only I get 15 miles (I weigh 20 stone).
In PAS 2 I got fed up testing at 40 miles.
