Battery Capacity Checker Tenergy 5-in-1 Cell Meter can display the estimated capacity and voltage for LiPo / LiFePO4 / Li-ion / NiCd / NiMH battery packs. Battery Capacity Checker Tenergy 5-in-1 Cell Meter can display the estimated capacity and voltage for LiPo / LiFePO4 / Li-ion / NiCd / NiMH battery packs. They do require special charging, so be sure to use the right charger for the job. Check your battery packs with Tenergy's 5-in-1 battery meter to see how it's performing. Tenergy 5-in-1 Cell Meter has 5 main functions: capacity checker, battery balancer, battery discharger, battery internal resistance tester, and ESC/Servo PPM tester. For LiPo/LiFePO4/Li-ion packs, it can also display the voltage of each cell, so you know when they need to be balanced. Use this function to quickly check if your battery requires charging before use. Note: To avoid overheating, refrain from using the discharge function for more than six minutes at a time. Because cell phones predominantly use this battery type, they are easy to find for reasonable prices. Tenergy 5-in-1 Cell Meter can display the estimated capacity and voltage for LiPo / LiFePO4 / Li-ion / NiCd / NiMH battery packs. But wait-that's not all! This cell meter can even be used to test movement and adjust your servos via PPM signal! Tenergy 5-in-1 Intelligent Cell Meter is a capacity checker, battery balancer, battery discharger, internal resistance checker and a ESC/SERVO PPM tester in one compact unit 35.00 25. In addition to allowing you to check the voltage of your batteries and view the capacity and internal resistance of each individual cell in lithium-based packs, this product functions as both a battery discharger and a battery balancer.Įvaluate the health of your battery pack and decide when to discard or replace it, discharge your pack to an adjustable threshold to improve its run time, and balance your batteries to optimize their performance and extend their lifespan. ![]() This is why I was hoping to use a proper battery tester that I'm sure will show me the right value of the internal resistance, instead of me measuring it with a voltmeter and getting it wrong.Do you yearn for complete and total mastery of your battery pack situation? Like a mystical amulet in a fantasy film, the Tenergy 5-in-1 Intelligent Cell Meter takes you one step closer to becoming an all-seeing and all-powerful battery wizard. ![]() My guess is that my measure of the voltage is wrong which makes the calculation of the internal resistance and the C rating wrong. Which does not make sense at all since the battery I bought is advertised with C rating = 1 Then I use the formula in this video to calculate the C rating ![]() Then I can deduct the internal resistance of my battery and the C rating. Tenergy 5-in-1 Battery Meter, Intelligent Cell Meter Digital Battery Checker Battery Balancer for LiPo / LiFePO4 / Li-ion/NiCd/NiMH Battery Packs 3999 Total price: Some of these items ship sooner than the others. I calculated it by measuring the voltage of the battery and the voltage across a load (3.3 Ohm) with the battery connected. I read that I need to calculate the internal resistance of a battery. I want to check the "true" C rating of the batteries that I bought. ![]()
