We strongly recommend that when installing the case, a soft pad be placed between the down tube and case (6mm number plate stickers are good). That the bulk of the case be supported on the down tube (not supported solely from the strap holders). In extreme cold conditions we do not advise using the battery.
We use only genuine new grade A cells and made up into complete batteries specially to order for us at our dedicated factory or here in the UK by our in house battery builders. We simply can’t buy a single battery, We have to agree to a production run of at least 20 batteries. The 0.2mm pure nickle sheet is electronically welded to the cells to give and safely handle this unprecedented “in triangle” huge power output with minimum internal resistances. The UK cases are fabricate here in the UK assembled by us after double checking everything.
Battery: Charging – Use
The battery is equipped with a very sophisticated ANT BMS.
The BMS can be turned off and on through an application for your mobile phone via Bluetooth (tip: sometimes it connects better first time if the battery is put on charge):
iPhone: ANT BMS
Connect to BMS and on the bottom of the home screen look for “control”.
On the control screen you will see the following (see fig/photo 11):
DO NOT USE “SHUT DOWN” (highlighted in red) as the battery will be totally disabled and can be restarted by plugging in you charger – using shut down can invalidate your warranty.
To turn the power off coming out of the battery (for connection and disconnection) use the DisMOS on/off by pressing the icon (highlighted in green). It may take a couple of seconds to respond. We do not recommend doing this away from a charger as sometimes it may not turn back on unless plugged into the charger. Turning off will stop the connection spark.
We warranty these batteries for 6 months.
Warranties are not transferable.
Space required, please see photo.
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.

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.
We reserve the right to slightly modify or change this product without notice.
