TORP TC500 controller is made to upgrade your Talaria Sting (all models) e-bike to an electric beast, be it on the road or at the tracks!

Only Torp controlers can talk to the OEM battery BMS and allow more power output WITHOUT undertaking a BMS Byapass – sensational!!

FOC technology assures the smooth and predictable power-curve from the beginning to the end of the ride. In combination with a custom 72V battery, you will be able to boost the power of your e-bike up to 25kW! More specifications

Plug & Play in the true meaning of words. No previous knowledge of electronics is needed to install. Just follow the installation manual and you are set to go in less than 20 min! We did all the tiresome tuning and configuration for you, so you don’t have to.

Battery 67V 3930Wh

#1 Usable power density is increased from a standard battery 1500Wh (heavily restricted LVC of 54V and not 48V) to 3930Wh

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

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

#4 Power increase of 12.5% and very noticeable increase in acceleration.

#5 Does NOT need an aftermarket controller or controller modification.

#6 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)

More volts, more RPM, more watts! There is no trickery here, just the obvious that others fail to see, and get annoyed that we’re making it difficult to be copied. We wont tell you how we do it, but the facts are really and genuine and really it’s all quite obvious  once you know how.  We have tested these batteries on several bikes for thousands of mile. Tested by Kilovolt bikes and reviewed by them (see YouTube)

Designed to run on the standard Sur Ron bike as a direct swap in battery but increase top speed by 10 mph (fully charged), increasing the range over 250%. Now add a a Torp TC500 and evrything just gets better!

Set your Torp TC500 controller to 165A DC and 420A Phase or 10.0Kw (10000Watts)

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 54V). For aftermarket controllers, that show battery voltage (like ASI, Torp, EBMX ) the voltmeter is not required.

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 the OEM Sur Ron Controller and NOT high power aftermarket controllers (we do offer an ASI BAC4000 set up for this battery at 10kW). If set for aftermarket controllers, please observe the specifications. Going over the recommendations could invalidate your warranty.

Charging port via an XT60 connector – Will need our “Marathon charger” found here:
The main battery to controller connectors we use are the same type as used by Sur Ron 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.

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.

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):
