Independent review from Jamie N
“This battery is a total game changer. 1000 miles in already and it’s just incredible. Seems to stay so exceptionally well balanced like <0.005V max and I’m consistently getting even better range than my mates with the 52V colossus Tesla Panasonic battery one even tho I’m blasting it far more and having even more fun
So so so very impressed with this build. It really is very special”
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 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 6 months.

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.
