Electric Bike 52v 21 Ah High Power Samsung 35E/LG MJ1 Battery & 4A Charger. UK Stock
Sorry No International shipping
Super Long range 14S6P 52v 21Ah Samsung 35E or LG MJ1 (high capacity 3500 mAh per cell and) with 4Ah UK charger. 50Amp Nominal BMS and double welded contacts).This is the highest Amp hours UK available downtube type battery on the market, designed to fit on down tube utilizing water bottle bolts. These 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 84 cells that retail in the UK for around £4 each! not including: BMS, casing , charger, shipping taxes AND FABRICATION.
We do not recommend these batteries for power output above 40A (2000watts), these will handle all 40A or lower 48/52V applications but have been specifically built for the Bafang BBSHD and G510 Ultra drive. They have Anderson connectors and are “plug and Play” for Bafang BBS02/BBSHD motors. These will power a cyc x1 or ASI BAC855 motor motor but power must be capped at 2200 watts – we will not warranty a BMS failure if purchased with a cyc motor.
Please ALSO note, these are genuine new cells and made up into complete battery specially to order for us at the factory or here in the UK by our dedicated battery builder. 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 (avaialabe 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.
