#1 Usable power density is increased from a standard battery 1500Wh (heavily restricted LVC of 54V and not 48V) to 4020Wh

#2 Range is more than doubled about 2.5 times the distance)

#3 Top speed increase (fully charged) for 6-10 MPH  improvement.

#4 Very simple to install (need battery lid hinge installation  – we provide and take 5 minutes – battery display on handle bar – 5 mins and we provide)

THE SECRET IS OUT!! (Now being copied a big American battery seller), this is a 67V 18S battery, More volts, more RPM more power (V x A= W)

Must be used with an aftermarket Controller.

This battery is not to be used with a third party controller set higher than 160A DC or 10Kw Phase 420A.

High Power Talaria Battery  4020 Wh  Samsung 21700 cell, with ANT Bluetooth BMS (works on IOS and Android) designed to fit inside the Talaria battery compartment utilizing the existing battery tray. The Cells are genuine branded cells specifically designed for large capacity storage and reliability. Other inferior cells used in cheaper packs simply can’t deliver like these. If you think the cost is high, these batteries have 208 cells that retail in the UK for around £6 each! not including: BMS, fabrication and shipping taxes.

The whole battery is fitted in  hand made stainless steel case designed to handle those inevitable and hopefully not painful “Offs” with hard off road rides and giving masses more protection. The casing is powder coated inside and out.

The battery does not have an integrated voltmeter. If you are using this with a standard controller, a handlebar voltmeter is supplied and can be simply plugged into the charge port of the battery to show voltage (empty at 48V). For aftermarket controllers, that show battery voltage (like ASI) the voltmeter is not required.

The battery does require an after market battery compartment lid of seat lifting kit (not inlcuded).

Battery compartment lids or Lifting Kits, can be found here:

Lid here: (Not Included): (£25 refund off lid issued with purchase of battery)
Seat Lift kit option #1 here (Not Included): (£25 refund off seat lift kit issued with purchase of battery):
Seat Lift kit option #2 here (Not Included): (£25 refund off seat lift kit issued with purchase of battery):

For bikes that do not have a display to show voltage, we include a handlebar mounted display to be located on the throttle side. Simply plug into the charge port of the battery when riding.


Please note this is a long range battery primarily designed to power  aftermarket controllers (we do offer an ASI BAC4000, Torp TC500 and EBMX X9000 set up for this battery at 10kW). If set for aftermarket controllers, please observe the specifications. Going over the recommendations could invalidate your warranty.

The main battery to controller connectors we use are the same type as used by Talaria to keep everything compatible. This allows you to swap your standard battery back should you wish.
Battery is in a super tough hand built stainless steel case designed to keep your battery safe in an accident and waterproof  except immersion or direct jet washing at the cable exits. Designed to fit straight into the bike and maximize the whole battery compartment (the hatch bolts need swapping  out with longer bolts that we supply – 2 minutes and simple). No movement- no rattles!

Please ALSO note, these are genuine new cells and made up into complete battery specially designed by us, built at our oversees  factory or here in the UK by our dedicated battery builders. We simply can’t buy a single battery, Thanks to Paypal fees, shipping and taxes the markup is minimal!

When connecting the battery to the bike and to avoid a spark. Turn the red trip switch on the bike to off.

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 for 12 hours first time.


* 12 Month Warranty is for manufacturing defaults and does not cover 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!

We do not warranty against water ingress (Only direct direct hose or jet wash,  being left exposed out side for extreme long periods can cause this).

We do not warranty against short circuits from incorrect battery to controller connection (using the bike red trip will protect from this).

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.
