The voltage value at that time corresponds to the number of cells of the electricity meter (eight cells in total). Although it is not absolutely accurate, the data of the other wheel is almost the same. The voltage value relative to the percentage is laboratory data and published on the Internet, I calculated based on this. The normal calculation is that this wheel is calculated using the working voltage of 3.7V, 3.5Ahx3.7Vx24x10=3108WH (officially marked 3200WH) 4, Check the official data of sherman, the lowest is 75.6V, so 75.6/24=3.15V The first published data tilt back at 74.5V, which was later revised to 75.6V 74.5V/24S=3.104V Edited July 10, 2020 by Andy Huang extra 2 Quote Link to comment Share on other sites More sharing options...

Thanks 18 minutes ago, Andy Huang said: 2, 3.5Ah x 50% x 3.82V x 24s x10p =1604.4WH The capacity of a single battery is 3500mA=3.5Ah, the voltage at this time is 3.82V, the electric capacity is 50%, 24 batteries in a string, a total of 10 strings in parallel Ah - the 3.82V (in your example) are the fault. As one already has the percentage of the full capacity, one cannot take the acutal voltage anymore but the nominal voltage (3,6V for ncr18650ga)! So 3.5Ah * 3.6V * 24s * 10p = 3024 Wh is full (100%) capacity. for 50% one has 50% * 3024Wh = 1512Wh... 3 Quote Link to comment Share on other sites More sharing options...
Andy Huang Posted July 10, 2020 Share Posted July 10, 2020 This is roughly what it means. The main thing I want to express is that after the first two of the eight cells disappeared, the battery has actually used about 70% of the electricity. It's not that we mistakenly believe that 75% of the electricity is still inside. When the LCD screen shows five grids, there is actually only about 10% of electricity. The safest way is to read the voltage value to judge the remaining power 2 Quote Link to comment Share on other sites More sharing options...

Would also be nice if they fix the enormous speedometer deviation so that one does not always get these wrong speeds and comparisons to read. Laugh me dead every time I read that the Sherman is so cool and you do not feel the speed and you think you are going much slower. This is not just a feeling, but the fact! I think we both always have the same thoughts about what we could buy and what we shouldn't buy for whatever reason. 4 Quote Link to comment Share on other sites More sharing options...
