This is a 72v 55Ah Battery capable of peak 32kW power (450A peak discharge until cut off on mosfet temp protection)

Our premium battery just got better!!! We swapped out the brilliant Molicel P42A and upgraded to leading Samsung 50S 21700 cylindrical steel jacketed cells (no puffy cheap pouches here). These cells give almost 20% more range than the Molicel equivalent and can supply the monster amp draw our controllers require.

We then swapped out our standard 330A BMS for a special order 450A BMS. This means these batteries can now continuously supply 250 amps and burst to 450A. This new super high output power can now handle bikes with the extra powerful: Sotion, EBMX and KO motors; yet keep the standard OEM Sur Ron motor running for huge long rides.

We then upgraded the casing from stainless steel 304 to marine grade 316 so absolutely no rust issues! Super tough and powder coated inside and out.

Also, by no mean feat, we massively improved the internal transfer of power by replacing all the connectors with pure copper sheet. This lowers resistance, reduces internal heat and make the battery even more efficient as it delivers sustained higher power to your controller.

The main battery to controller connectors we use are the same type as used by Sur Ron but we use two sets to share parallel the power. This reduces heat, transfers load more efficiently and keeps the connectors from overheating.

The 72 55Ah Sur Ron Battery 20S11P 72v 3960Wh Samsung 50s 21700cell. The cells are genuine branded cells specifically designed for high output discharge and sustained high drain. Other inferior cells used in cheaper packs simply cant deliver like these.

Our last and most recent upgrade is to supply one direct set of discharge cables to the controller via a high capacity QS8 connector using very large 6AWG cables (this reduces internal resistance and heat build up) and a separate second set of discharge cables using the original 8AWG cable via a Supra D6 connector to the OEM loom via circuit breaker. This means all your bike accessories are still powered. Some believe that not using the circuit breaker direct to the controller removes the safety of the circuit breaker. However, all our batteries have a full working BMS. Any power shorts or irregular current and the BMS shuts down, Much more sensitive and accurate than a mechanical breaker (you may note that the Sur Ron Ultra Bee does not use a circuit breaker and relies on the BMS alone).

Fitting

The battery uses two sets of discharge cables. One to fit the original bikes connector (for Talaria we supply an adapter so it can also fit a Sur Ron too). The second goes to an additional cable that we provide that is fixed direct to the controller. This enables the power to be fed In Parallel increasing the electrical flow, reducing resistance and reducing harmful heat. It shares the power delivery and takes the strain away from the original loom. However, these must be connected in a correct order (simple instructions supplied).

Torp do not like direct power to the controller (our 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 (10A MAX):https://www.electroncycles.co.uk/product-category/batteries/

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.
