52v 31.5Ah (14s9p) Samsung 35E on/off switched XT90 connector Ebike, Electric Bike, Triangle Battery with 5A UK Charger
This is the very best of battery technology: 14s9p Ah battery containing 126 Samsung 3500mAh cells, 60A BMS (battery management system) with 5AH UK charger. 60 Amp Nominal and 80Amp Maximum BMS. Designed to fit within the triangle using a choice of 9 Velcro fastening points.
These type of cells used in high amp discharge installation where the combination of 10A per cell maximum discharges yet a storage capacity of 3500 mAh. They are specially designed for high output discharge. Other inferior cells used in cheaper packs simply cant deliver like these in this scenario. These batteries are particularly good for: large rear hub systems of 3000watts, Cyclone mid drive and BBSHD conversions. These cells can supply a nominal 3000 watts (depending on charge state) .
If you think the cost is high, these batteries have 126 cells that retail in the UK for around £5 each! not including a BMS, casing , charger, shipping taxes AND FABRICATION.
These are factory made in the UK using the very latest in spot welding and nickel strip.
Please ALSO note, these are genuine cells and made up into complete battery specially to order for me at the factory.
The cases are extremely tough and weather resistant to a high degree. They are designed to take a medium impact.

* 6 Month Warranty is for manufacturing defaults and does not over miss use or accidental damage. Opening battery will void any warranty.
When Charging, Please turn on the battery by placing the red button “in” and turning on the charger, Then connect both devices.
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.
