POSTED JANUARY 10, 2019 - The discharge rating of a LiPo battery is directly affected by the temperature of the battery. When the temperature of the battery is below 50° F (10° C), you’ll start to notice performance drops; significant issues start to occur when the battery gets below 20° F (-7° C). The colder the battery the bigger the drop in C rating and resulting drop in performance. Degraded discharge ratings will diminish run time, decrease top speed and reduce overall power; this is because the battery voltage will sag down more under load due in increased resistance. This strains the battery and will reduce the life expectancy and performance of the battery. It will also add additional stress to the ESC’s capacitors and could lead to potential damage. Charging the batteries when they are cold will result in similar stress to the battery and shorten its life.
Running higher C rated batteries can help somewhat, but even then you’ll want to keep them as warm as possible. When the batteries are being used in the vehicle they will stay warm as you’re pulling amperage out of them; you just don’t want to let them start out cold. Temperatures below 0° F (-20° C) will cut your C rating in half! EEK!
So what can you do? Don’t let your LiPos sit out in the cold before you go out for a run. Use rice heaters, hand warmers or your own body heat to keep the batteries at a cozy temperature before use. Also don’t charge your LiPos when they’re cold as this can result in stress and damage to the cells. Moving to a warm destination is our last tip, and the most expensive. :)
𝗧𝗘𝗖𝗛 𝗧𝗜𝗣 - ESC FANS (Category: SURFACE)
POSTED DECEMBER 20, 2018 - This is a quick one, but you just may not know this. If you run a Castle ESC other than these three, your fan runs from start up to shut down. All ESCs with fans are serviceable and replacements can be found right here: http://www.castlecreations.com/service-parts-4
𝗧𝗘𝗖𝗛 𝗧𝗜𝗣 - Lost Sensors Solution (Category: SURFACE)
POSTED FEBRUARY 18, 2018 - R/C vehicles, and the components within, have a tough life - landing extreme jumps, experiencing accidental collisions, splashing through the occasional puddle or perhaps an entire pit of mud. We want to make certain you are never grounded, and that's why we recommend running in Smart Sense Mode. Smooth starts, excellent torque, and low-speed driveability with an ultra-powerful and efficient dynamic sensorless mode to boost motor efficiency. The cherry on top? Smart Sense will instantly transition to sensorless operation should the ESC detect a bad sensor connection. An audible alert can advise of the ESC losing connection, but no worries, you can address that when you are done running. You can learn more about Smart Sense by clicking this link: http://www.castlecreations.com/smart-sense
POSTED MARCH 13, 2017 - The video below is an overview of the new Auxiliary Wire Programming Mode "Rock Race/Crawler Mode. This setting is available in Firmware V2.02 for the Mamba X, Monster X, Micro X, and Mamba XL X. You can find more information about Rock Race/Crawler Mode by clicking this link: http://www.castlecreations.com/crawlermode
POSTED OCTOBER 15, 2018 - Team Castle Driver Jon Holt explores the new Castle setting Drag Brake Ramp. Castle firmware V2.06 for the Mamba X, Monster X, Micro X, Mamba XL X, Sidewinder 4, and Sidewinder Micro 2 was released on 10/15/18. The Drag Brake Ramp setting is under the "BASIC" tab in Castle Link or B-Link programming. The ESC will gradually increase the intensity of drag brake as throttle returns to idle. You will be able to adjust the rate at which drag brake increases from very slow to disabled. Think of it as our contribution in controlling the amount of broken driveshaft replacements. :)
