Sur Ron Battery 72v 50AH Gladiator Samsung 50S 18Kw. Designed for those who want a more affordable, decent range battery that can still max out an OEM motor and keep the weight and size down, keeping the bike light and nibble. Sits just 5mm higher than the OEM battery in the bike. Just like its bigger brothers in the Electron Cycles Battery List, we have used the best, super tough, 316 marine grade stainless steel casing, powder coated inside and out, it has the big ANT 220 BMS, a single QS8 6AWG cable and pure copper sheet connections. Supplied with a high power bike side loom.

For those wanting to run a Torp controller, this is the perfect battery as we only use one cable and the controller can be maxed out. The TC1000 will run up to 18Kw with this battery.

Cells

There are 200 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.

Power

This is a Sur Ron Battery 72v 50AH Gladiator Samsung 50S 18Kwpower as limited by the 550A (peak/burst for 10 seconds) by the Ant 550 BMS.

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

For the main Sur Ron Battery to controller connectors we use one direct set of discharge cables to the controller via a high capacity QS8 connector using very large 6 AWG cables (this reduces internal resistance and heat build up).

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 that the Sur Ron Ultra Bee does not use a circuit breaker and relies on the BMS alone).

Connecting To Bike

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 the battery has no special order.

Battery Charging

First time charging is VERY important. Always connect the charger to the battery with the charger powered up at the mains first. This will stop a Connection Spark. The battery needs a Balance Charge on first charge. Please charge for 12 hours first time. Always charge your battery in a safe place and never unsupervised.
