Review on Trouver Power 11 Cordless Vacuum Cleaner, white/red by Felicja Burska ᠌

according to the first drawback, in principle, nothing can be done to make such a case and that's it on the second, you can order separately or cut out from the camera from KAMAZ (SRT to help) on the third, I’ll tell you in more detail, since the trouble is frequent and 100%, the battery is assembled in this model just don’t care, since there is no normal BMS, that is, the discharge charge regulator of each bank in the assembly, then after a month or two of use, the battery either refuses to charge or is discharged literally in 20-40 seconds or even faster; this is due to the absence of a normal BMS, it’s not there, but it controls absolutely nothing!, the solution to the problem is this, you open the battery (carefully there are bolts, look carefully otherwise you will break their fastenings) and then take a Chinese (200) charger, it will do even from flashlights that charge 18650 batteries, the same ones are in our vacuum cleaner, then just charge the batteries manually one at a time with this charger, do not reverse the polarity, otherwise the charger will burn out (usually this ends if there is no protection in it) after you have charged everything batteries approximately (preferably) up to 4.1-4.2 volts, the vacuum cleaner will still work and hold a charge as when you bought it, but after 1-2 months you will have to repeat this ritual, in general, such a trouble with Akum, the problem with the battery is due to the fact that 1 -2 elements in the assembly sag in voltage too much and as a result the other remaining ones are charged to their 4.25 and this useless board inside considers the charge to be over and as a result we have m 24.8 volts, but when the load is applied, the charge drops to 22-21v, which is about 40-50% of the charge, then there is a drawdown of the very batteries that are not already charged and we get that the vacuum cleaner sits down literally in 20-40 seconds at medium power. As a result, if you are not an electrician, or at least do not know how to use a soldering iron at the amateur level, do not go there, give it to someone who can! To the question about the battery, but you can do something to get rid of this trouble, I answer, you can, put a normal BMS!
