We designed this over the last 6 months, designed and redesigned. The results are staggering and speak for them selves:

70 Amps continuous discharge but peaks of 100A!

34Ah @ 52V  giving 1768 Watt Hours – absolutely huge for a triangle in frame battery!!! (this is nearly 4 times bigger than the std Bosch Powerline battery and double of our very big 17.5Ah)

Ant Bluetooth BMS giving series monitor and on/off via your smart phone (no leaky switches)

Fully sealed  high water Resistance case (SEALED at the side panel join, so no water ingress – smart phone on/off) Only full submersion will let water in through the wire exit grommets.

0.2 mm laser cut pure nickle sheet welded.

98  x Panasonic Tesla 21700 cells. 14s7P.

Anderson XT 150 Connectors for discharge and xt60 connectors for charge. Your motor side will need adapting by you (xt 150 and Anderson Powerpole supplied)

Full genuine OEM Velcro straps are supplied for quick and simple fastening to the bike.

Massive power 6A charger .

We strongly recommend that when installing the case, a soft pad be placed between the down tube tube and case (6mm number plate stickers  are good). That the bulk of the case be supported on the down tube. In extreme cold conditions we do not advise using.

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 laser cut and then 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.

We warranty these batteries for 12 months!

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.

* 12 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. 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.
