Sur Ron Battery 81.4v 22s REALLY ROCKS!
Sur Ron Battery 81v 50Ah Trojan 22s 4070Wh for 25Kw High Power Long Range really rocks! Why? Because an electric motor spins so many times per volts. Then add more volts and you get more spins (RPM) and more top speed. But here is the geeky and cool bit (literally): Amps create heat so the less amps you use, the cooler stuff runs. Heat kills electrical components as the heat literally melts soldered contacts internally, insulation burns off and glues melt.
This is a Sur Ron Battery 81.4v 22s 4070Wh 50Ah Trojan for 25Kw. A High Power, Long Range Battery. It is capable of peak 25kW power (450A peak discharge until cut off on mosfet temp protection).
Cells
Cells (there are 220 in this battery) all have internal resistance. The more resistance, the more heat they produce, until they start to damage. With this low resistance the cells are able to supply enormous amounts of power without over heating.
Power
Sur Ron Battery 81.4v 22s 4070Wh 50Ah Trojan for 25Kw as limited by the 550A (peak/burst) by the Ant 550 BMS. A genuine constant power of 17.9Kw (220A non stop). We recommend 18Kw continuous at 230A discharge with a burst setting of 25Kw.
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 QS8. This reduces heat, transfers load more efficiently and keeps the connectors from overheating.
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
Fits straight into the bike but you wil need to use the battery lid spacer provided free and change your bike side battery cable to the one we supply. This set up is Torp complient as the power still runs (at you choice) through the Red trip switch.

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”.
