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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eHeres a great review from a respected blogger:\u003ca href=\"https:\/\/www.instagram.com\/reel\/DM8VLbSoKqd\/?igsh=MXg2YW40MzM5em15Yw==\"\u003e https:\/\/www.instagram.com\/reel\/DM8VLbSoKqd\/?igsh=MXg2YW40MzM5em15Yw==\u003c\/a\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003ch4\u003eDescription\u003c\/h4\u003e\n\u003cp\u003eSur Ron Battery 81v 22s 4070Wh Trojan High RPM Samsung 50S  is capable of peak 32kW power ( peak discharge for 51 seconds until cut off on mosfet temp protection).\u003c\/p\u003e\n\u003cp\u003e18kW continuous at 250A discharge runs for 4 minutes and 16 second continuous load until cut off on mosfet temp protection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRiding Range:\u003c\/strong\u003e 181.5 km (laboratory result measured at the average speed of 25 km\/h)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBattery Pack:\u003c\/strong\u003e Grade A 220 * 21700 Cells (Samsung 50S, volts difference less than 0.01V after 10,000Ah cycles)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBattery Cell Lifespan:\u003c\/strong\u003e Minimum 70% of capacity after 3 years\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStandard Power:\u003c\/strong\u003e 19.2 kW\/ 250A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeak Power:\u003c\/strong\u003e 32kW\/250A Peak (550A peak BMS for 11 seconds set to 400A peak for this battery)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVoltage Drop:\u003c\/strong\u003e Battery voltage drops 6V at 250A\u003c\/p\u003e\n\u003ch4\u003eCells\u003c\/h4\u003e\n\u003cp\u003eThere are 220 cells in this battery and all have internal resistance.

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).\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eFit the high power cable we provide to directly replace the OEM cable that came with the bike.
