Thank you for watching. You can see below timeline to charge FIMI battery with iMax B6 with above video. 0:37, 0:47, 0:54, 1:13, 1:18, 1:29, 1:34, 1:40, 1:45 Before starting to charge iMax B6, you need to activate FIMI Battery by doble cricking. Hope you can understand what I did.
Hi, my battery of the FIMI X8 se 2020, despite a few charging cycles, after full charge with the original charger I have these values: 4.22V 4.07V 4.15V. Solve by charging the battery with ISDT Q6 Plus? Where can I find a suitable charging cable, perhaps like the one in the video? Thank you
Thank you for watching. Your battery voltage difference seems exceeding the limit. Did you over-discharge the battery during the flight? If you did over-discharge, I think Battery Management System (BMS) in the battery refuses to start the drone. I did 7,000m + flight with 2018 ver. and did over-discharge to come back to take off point and the battery was completely destroied. Anyway, I tried to find the charger cable I have but (please see attached AliExpress charger+cable) but no find the cable portion only. www.aliexpress.com/item/1005001571493105.html?spm=a2g0o.cart.0.0.63fb38da2UXbui&mp=1
Hi, My battery readout is cell 1 is showing 3.61V and cell 2 and 3 have 4.18v, is the battery beyond repair? it never crashed or fully discharged, Can it be rebalanced somehow? any advice would be appreciated, tks
Thank for watching. It seems one cell was not working properly even though never being crased or over-discharged. Once too much voltage difference between cells were detected, Battery Management System (BMS) can not allow to accept that battery for flying. If you are expert, you may open the battery and try to charge the cell showing 3.61v to the fully charged level. However I do not know if BMS accepts it. Anyway, I do not recommend to use such battery for flying. Battery price is way lower than the drone which may crash from way high due to inferior battery.
Does charging with the B6 take the same amount of time as with the stock charger? Is it normal for the voltage to drop to 11.8 volts when charging, doesn't the battery need 13.1 volts?
Thanks for watching. Above YT shows how to charge with B6 and discharge X8 battery. I usually charge X8 batteries with stock charger and car battery type charger so I do not know how long it takes to be fully charged with B6 May be takes longer as Amp. set 3A is reducing during the charge. You can try by yourself.
This fan is very handy i have to say👍 How many cycles did your destroyed battery from the last range test have? Can you feel the differences between your 3 cycles lipo, compared to your 97 cycles lipo? This could be a future test, comparing these two..
Thanks for watching and your comment. Cooling fan is originally made to cool down of F3A pattern plane (160 4cycle engine after landing) which I selected one of PC cooling fan with bigger air flow. My battery history is No. 1 (Feb 4, 2019 together with X8 delivered) now 97 cycle and voltage difference in 3 cells is 0.02v. No. 2 (Purchased May 8, 2019) - at 64 cycle killed by over-discharge after returning flight from 7,264m. It was pilot error that manual return home was done which consumed more power and 70m short landed due to over-discharged. This is only one over-discharge with this long range flight. No. 3 (purchased Sep 24, 2019) Now 51 cycle (0.01v difference in 3 cells). No. 4 (purchased Jul 14, 2020 after No. 2 battery was killed). Now 4 cycle (0.01v difference). I feel No. 1 battery (97 cycle) is very slightly deteriorating but no problem to use say 20% remaining level. You can see attached sheet. Close to bottom line is for battery history and Flight Record. docs.google.com/spreadsheets/d/1MghIcdNIom1Fj6nHkqPca1OvwRelI0lQ1QDUz1jvz4E/edit?usp=sharing
@@aiolosimport1259 Great video and explanation. How low can these cells go before they are damaged? I saw a video from another youtuber claiming fimi have set their BMS to register anything under 15% as an overdischarge! Does that sound very accurate to you? Big thanks 👍
@@Altair885 Thanks for watching. For battery calibration, put drone in the air until reaching 10% remaining (instruction says land at 15% remaining and leave drone on the ground until 0% remaining) to shorten waiting time. Flying until 10% remaining does not cause problem, nor over-discharge. You can see below YT which shows battery calibration and flying until 10% remaining. ua-cam.com/video/RnRfCOOTCSY/v-deo.html I had long range flight test and reached 7,264m (2018 ver. spec says 5km range) with Yagi antenna attached. On the return home, I made mistake - manual RTH with full throttle and course deviation which consumed more battery. I intentionally tried to return as close as taking off point even battery was over-discharged and killed because I wanted to avoid falling down to other properties or person. So this is 100% pilot error and battery was killed but drone came back just short land 70m from taking off point. You can see below YT to show over discharge condition. Only one over-discharge kills battery. ua-cam.com/video/ni_8W29V9G4/v-deo.html So 10% remaining is no damage and my first battery is one over 125cyle and still working O.K.
@@aiolosimport1259 Thank you so much for taking the time to reply in such a detailed manner! I feel a lot more confident now I have a better understanding. I have only recently received my new x8 2020 that I ordered, however before flying it I have been watching as many videos as possible to try and avoid any mistakes and gain some knowledge, unfortunately I came across this video: ua-cam.com/video/t3w1V_8a-WU/v-deo.html Which caused me a bit of concern, guess I shouldn't be so gullible, it seems this person has an axe to grind with xiaomi for some reason. Anyway I really appreciate your help and after seeing the videos you linked to my mind is more at rest. Regarding the damaged battery I noticed that the error message stated that the battery couldn't be used due to imbalance, do you think in that situation if it were possible to charge the individual cells one at a time some order of balance can be regained and the drone would allow the battery pack to be used again? Or is it once the BMS for that pack reports a fault even changing the cells for new ones wouldn't work? Big thanks, subbed to your channel 💓😃
@@Altair885 For battery treatment, I would like to add that first 10 or 20 cycles of charging, you better to land at 30% remining when low battery warning popped up for break-in for use of long life. 2nd, I killed one battery for return the drone as close as taking off point. I tried to charge that battery but seems BMS can not allow to be used on the drone. More over, I do not want to use this battery (once over-discharged) as there is a risk that drone may fall down due to battery error. It is not wise to use damaged battery for possible risk. New battery is way cheap and safe.
How did you bypass the battery check, my iMax B6 wouldn't allow charging without the monitor port connected. Thanks.
