52v 16Ah Smaller Cased, Semi High Power Long Range 50A/2000W Down Tube Battery + 4A Charger
More powerful than our nearest 52v 19.5Ah. This is managed by a 50A BMS and 5 parallel cells all handling 10A each 18650 cells. Cells are either Samsung 32E or LG MH1.
The Samsung 32E or LG MH1 are extremely similar cells (we have not mixed cells, just mixed the whole batteries on the shelf) 3200Mah per cell and with 4Ah UK charger. 50Amp Nominal BMS. 5p x 10A cells and designed for 2000w max motors and pure nickle welded contacts). Downtube type battery, designed to fit on down tube utilizing water bottle bolts. This battery is physically the smallest we do yet still have enough power for the BBSHD and CYC Stealth motors. These cells are volumetrically small than the 21700 yet more powerful (we can squeeze more cells in).
We do not recommend these batteries for power output above 50A (20000watts), these will handle all 50A or lower 48/52V applications but have been specifically built for the Bafang BBSHD and G510 Ultra drive and CYC Stealth. They have Anderson connectors and are “plug and Play” for Bafang BBS02/BBSHD motors.
Please ALSO note, these are genuine new cells and made up into complete battery specially to order for us at the factory. These are not “off your shelf” batteries that are found similar to by other vendors. We buy the same cases and there it stops – everything is bespoke to Electron Cycles Limited. We simply can’t buy a single battery, We have to agree to a production run of at least 30 batteries. 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.
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 (available on Ebay) for additional support.

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.

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.
