We normally only sell our own bespoke batteries, but when we found these, we were so impressed that we decided to buy some in and sell them ourselves.

Tough hard ABS cases that are water sealed, LED battery display and quality on/off swatch.  These are NOT made by UPP. There’s another well known manufacturer (low quality) hard case seller out there, that simply does not manufacture at a high enough quality level (we booted then four years ago). Our supplier took the case idea from them, went back to the drawing board and decided to do it properly!

This battery is suitable for our ASI BAC855 72v system.



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 hours – 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.



* Warranty, due to the nature of use of these devices (off road) warranty is limited to 12 months from date of purchase for the battery and 6 months for the charger. Any damage the result of water ingress, alteration, may void warranty. This includes shortening of cables and changing connectors. It is the owners responsibility to proof against water ingress and not use in unacceptable very wet conditions, or use direct water from hose/washers. Any alteration modification to this controller or its subsequent wiring, even cutting the power leads to make shorter will immediately invalidate any warranty. Even battery disconnected, the controller can still maintains current and can be shorted/damaged. The controllers are waterproof, but can still suffer from water damage through the connector and hence are not covered for water damage. Controllers are not covered by warranty after 14 days.
Using high PAS in a high gear under heavy load may cause the controller to overheat (power level 9 in a small rear cog). Gears should be used going uphill or any other heavy load.
Attempting to reprogram the controller may cause damage.
Warranties are not transferable.
We reserve the right to slightly modify or change this product without notice.
