Cells

There are 220 cells in this battery and all have internal resistance. The more resistance, the more heat they produce, until they start to damage. So with this low resistance, they are able to supply enormous amounts of power without over heating.

Exoskeleton /Casing

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

Connectors

The main Sur Ron battery to controller and battery to bike connectors we use are a  QS8 on a heavy duty 6 AWG cable. This allows higher power flow and less resistance than a standard cable and connector. We supply a free upgraded high power loom with the battery.

Low power adapter for those who do not want to change bike side loom – Max power 12Kw if used

Domestic Electrics

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.  This is much more sensitive and accurate than a mechanical breaker (you may note, for example that the Sur Ron Ultra Bee does not use a circuit breaker and relies on the BMS alone).

Fitting

Fit the high power cable we provide to directly replace the OEM cable that came with the bike. We supply the battery lid spacer and aluminium hinges.
