15kW continuous at 200A discharge run for 4 minutes and 16 second continuous load until cut off on mosfet temp protection.

However, going up and down the throttle (off road riding) will allow bursts of upto 28Kw (400A) although 21kw is max recommended

We upgrades this very popular battery to handle more power. The More nickle sheet (lower resistance and heat). Bigger more powerful hybrid BMS giving 80 Amps more, A new stronger lifting stapes and new stunning graphics

Please make sure yurt controller is set to a power rating that will not damage your motor. The battery is the “fuel tank” and it is the controller that controls  how much “fuel” (Power) it takes and gives to the motor.

This will not work with the original X Controller.

These power packs are designed for ultimate power supply and are 57.5% bigger watts hours (3024) compared to the standard battery (1920) and able to give out 3 times the power (discharge -amps)

High Power Sur Ron Battery 20S10P 72v  3024Wh 42Ah Molicell p42A 21700 cell (high power 4200 mAh  per cell),  with ANT  Hybrid Bluetooth BMS (works on IOS and Android) designed to fit inside the Sur Ron battery compartment utilizing the existing battery tray. The Cells are genuine branded 21700 cylindrical cells (not cheaper pouch) specifically designed for high output discharge and sustained high drain. Other inferior cells used in cheaper packs simply can’t deliver like these. If you think the cost is high, these batteries have 200 cells that retail in the UK for around £8 each! not including: BMS, fabrication and shipping taxes. Now with marine grade 316 stainless steel powder coated cases. 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.

Torp do not like direct power to the controler 9our second cable), so please just do not use the additional power cable. We do not like to remove these as often buyers transfer batteries to another bike.

THIS KIT DOES NOT INCLUDE A CHARGER. Chargers can be found here:

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 mark-up is minimal!

When connecting the battery to the bike and to avoid a spark. Turn the red trip switch on the bike to off. Connect the older original power cable and then turn the red trip to on. Then connect the new power leads. Removing battery has no special order.

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.

For bike 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.

* 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. Th battery is waterproof but will not take direct water flow to the discharge cables form a jet wash or hose pipe – this is not covered. 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.

Please note, charger is not supplied but can be found here:
