  • Rated to 3000WThe manufacturer rates it 1500W to 3000W, so on a 2000W kit it is never near its limit.
  • Rack and straps both includedMount it on the rack or strap it in, whichever suits your frame. The only pack we sell that comes with both.

Will it fit your frame?
1Cut the shape from cardboard. Mark these dimensions onto card, cut it out, and hold it inside your frame triangle. This is the tallest pack we sell, so this check matters more here than on any other battery.
360 mm long 195 mm tall 97 mm wide 8.5 kg · needs an 18 inch or larger frame
2Mind the height. At 195 mm this is 38 mm taller than our 25Ah triangle. If you have measured for that pack and it was tight, this one will not go in.
3Rack or straps, your choice. Both are supplied. The rack is neater and lockable; the straps suit frames where the rack bolts will not line up.
?Still not sure? WhatsApp +44 7493 275057 with a photo of your frame, or bring the bike to the workshop between 08:00 and 18:00 and we will offer the pack up against it.

HS-II or Smart battery — which should I pick?

Both are 52V 30Ah triangle packs at 1560Wh. Same capacity, same range, same frame requirement.

HS-II (this one)LG 21700 cells, rated 1500W to 3000W, 1000 cycles. Rack and straps both included. The straightforward option if you want the range without paying for extras.
Smart batteryOur own pack. 84 Samsung cells, 50A BMS and Bluetooth — you can see individual cell voltages, cycle count and temperature from your phone, and cut the pack off remotely. About £45 more.

If you want to keep an eye on the pack’s health over the years, the Smart is worth the difference. If you just want the miles, this one does the same job.

Charging and looking after it
ChargingUse the 5A charger supplied. A full charge from empty takes five to six hours. Charge on a hard non-flammable surface, never unattended and never overnight.
Cold weatherCharge it between 0 and 45 C. Do not charge a pack that has come in frozen from a winter ride — let it warm up to room temperature first.
StorageIf the bike is going away for a few weeks, leave the pack around half charged rather than full or flat, somewhere dry and cool.
Stop using it ifthe case is swollen, cracked or dented, the pack gets hot, or it behaves oddly. Move it somewhere safe away from anything that can burn and ring us.
Questions we get asked
What motor will this run?Rated 1500W to 3000W. On a 2000W kit it has real headroom, and it will run a 3000W system too.
Will it fit my frame?It needs an 18 inch or larger frame. At 195 mm tall it is the biggest pack we sell, so cut the outline above from cardboard and try it before ordering.
Does it come with straps or a rack?Both. It is the only pack we sell that includes the two, so you can mount it whichever way suits your frame.
How is it different from the Smart battery?Same capacity and range. The Smart pack uses Samsung cells and adds Bluetooth so you can check cell voltages and pack health from your phone. This one is the simpler, cheaper option.
Can I post it back if it does not fit?Not through the post. Lithium packs this size are restricted goods and travel by road courier only. Ring 0161 706 1851 and we will arrange collection.
What if something fails?Ring 0161 706 1851 or WhatsApp +44 7493 275057. Twelve months on manufacturing defects, and because we are a workshop rather than a warehouse we can usually diagnose a fault from a photo instead of making you send it back.

Read before you buy — battery safety This is a high capacity lithium battery. Charge it on a hard non-flammable surface, never unattended and never overnight, and only with the charger supplied. Do not charge a pack that has been dropped, crushed, or is showing damage or swelling. If it gets hot or behaves oddly, stop, move it somewhere safe away from anything flammable, and contact us straight away.
