PARKSIDE Smart Battery Bluetooth Problem Solving Part 2

[@tcirit]

You found a good way to relieve stress.😅

Boa noite... Adoro as suas reparações e, tiro grandes ajudas para reparar algumas das minhas coisas também. Relativamente a estas baterias, se comprar novas e, para evitar problemas... O que devo fazer? Só eliminar ( retirar ) o módulo bluetooth? Obrigado. Cumprimentos e, boas festas.

I think that Parkside (Grizzly tools) will gain insight into the use of their tools (know your customer) through this "smart" addition (Phone home smart charger). Respect for Ercan for the way of making film, the message comes across clearly :-) Kudos to the investigative journalism ***** We all benefit from this in the end.

[@Ovi_B]

I have one question, do you know if those modules can be brought from somewhere? I have a battery with the same bluetooth module dead.

[@ErCanEverything]

I'm sure it's available on Aliexpress but I haven't researched it.

[@Ovi_B]

@@ErCanEverything I searched for it but didn't find where from to buy it. Only some datasheets, etc.

[@IkkaDoes]

Hiz thank you for your video, where you can buy spare parts for battery?

[@FUTUREXROCKSTAR]

Good morning. Is it preferable on a new battery to disconnect the BT to avoid breakdowns? I used a scalpel to desolder only the 3v terminal of the BT module, I placed a plastic between the terminal and the PCB, the BT no longer works.... To reconnect it I just have to remove the piece of plastic and put a soldering point ps: i own an potential battery with BT fail

[@tez1954]

I also have an issue with my battery and in about to hammer it down, theres just i cell Bat- and Bat1 that is unbalanced from the other cells, the bms doesn't balance that cell in particular and keeps it 0.40v below the others, could this be caused by the Bluetooth module?

[@ErCanEverything]

This is not from the bluetooth, try to balance them using CC/CV power supply and after a while the voltage lags behind the others, so these cells are damaged or check for signs of wetness on the board.

[@mateipetresergiu5795]

Hello my fryends !Diz paste plz name ?

[@ciprianwinerElectronicManiac]

If it is of any use. I had a similar problem with my 4Ah and after 1 year I found the solution. The bms is trying to balance that always low voltage cell and it is discharging it. The only fix for that is to disconnect the balancing transistor for that cell from the IC. I did that after trial and error and removing one resistor.

[@ivosscz]

Have you discovered the behavior of the battery after removal of the BT module without disconnection of the whole BMS? Does it remember the last setup of the battery shut off parameters? I am considering to remove BT modules from new batteries. It would be fine if it remembered the ECO preset, which I prefer for 4 Ah battery (for maximum performance I use 8 Ah batteries).

[@Ohm7111]

Settings are stored in the MCU not in the BT module. I tried lock my battery with PIN code and than I removed BT module. The battery was still locked and was not working in my drill. I soldered the BT module back, removed the PIN code and the battery works fine. Some comments says that the BT module is not the problem, but the 3.3V regulator is.

[@Ovi_B]

I have another question, do you have any clue which might be the cause of bt module failing? This problem seems to be systematic as long as so many people have it. For example I suspect that is related to bt module firmware update. I have two batteries and tried to make bt firmware update. For one it worked for thew other it didn't (and have the problem described in your videos, 3V3 and that resistor gone, overheating, etc).

[@krasigichev]

Most likely, the linear regulator is not specified for the maximum voltage - at some point it fails because running out of spec, and lets higher voltage to go on the output (more that 3.3V). This puts pressure on the poor BT module that was specified to handle 3.3V only. The BT dies and starts consuming higher that expected current (so, the 100mA that ErCan measured). Those 100mA over 20Ohms are too much for 0805 or 0603 resistor and it fails too. If you have an old battery that still works, open it and do some "maintenance" - replace the regulator with one from reputable supplier, and make sure it handles at least 30V. For example, MIC5233-3.3YS from Micrel, ups, Microchip now. But be sure that it is a legit one - Farnell, Mouser, Digikey, TME are good choices to buy it from.

[@Ovi_B]

@@krasigichev "designed by clowns supervized by monkeys", like some Boeings.

[@nickpelov]

0.3V * 0.016A = 0.0048 W. that's less than 0.1W of standard 0603 resistor. I think the BT module failed first and that's what burned the resistor. anyway, BT battery in this case is a stupid idea. it doesn't add any value. 👍

[@krasigichev]

Nope, most likely the regulator dies from overvoltage on the input and raises the 3.3V rail higher.

[@harrx7756]

hello, can you tell me which component is responsible for the duration of the charge level indicator? My LEDs are lit continuously. Thanks friend

[@TheOgi22]

01:32 I 100% know what you think 😂😂😂 BTW the stupid BT modul turns On automatic, when you put battery on charger. Aaaargh. Pls, do you know, what to do, to turn the BT module permanently Off? Just usnoldered it? Or disconnect 3,3V line?

[@battedtomcatnlnl153]

When do you get payed be parkside?

[@ErCanEverything]

😂😂😂😂😂😂😂😂😂😂😂😂😂😂 Parkside only pays Arnold

[@dyslectische]

Wy have those battery? Parkside still sell non bluetooth models.

[@DjaniAgain]

6:55 I can see where things go 😂😅🤣

[@ErCanEverything]

😂😂😂😂😂😂

[@ricardo4527]

Wow, thanks for this. I am currently looking into fixing 2 broken batteries myself. Is there any danger to the batteries or circuit when I remove the Bluetooth module?

[@ErCanEverything]

I worked without removing the BMS to show you a quick example, but you must remove the BMS to work safely. Otherwise, the consequences may be severe! This is the first part: kzbin.info/www/bejne/fJeag2aumrZpnsUsi=rayba_PenxdOjM63

[@ricardo4527]

Could you tell me what parts I have to remove for that ?

[@ErCanEverything]

You need replace 7533-1 and R44 20 Ohm resistor and Remove BT Module

[@Κωνσταντινοςκ9]

​@@ErCanEverythingi cant find 7533-1. Is there any similar code? For example a 3,3v regulator at 1Ah would do for the job?

[@ErCanEverything]

@@Κωνσταντινοςκ9 Whatever 3.3V regulator you can find will work

[@AAAlexAlex]

Почему они выходят из строя ?

[@krasigichev]

Cannot withstand the input voltage - either BEMF from the motor, or while charging.

[@tcirit]

Could you tell me how many mAh the batteries in the 8Ah battery pack are? 2500mAh?

[@djroskedjroske]

They are 4000mAh battery type 21700.

[@michelvandenbroek4168]

I removed the bluetooth shit of my batteries hopefully they last longer now

[@pawelw.9172]

already tested in poland, if the stabilizer fails without the bt module on the way, it will burn the microprocessor and then bye bye battery. 3.3v stabilizer is the culprit.

[@blackbird9813]

​@@pawelw.9172 and how solve this problem?

[@Ray_of_Light62]

Without a load, the regulator will start oscillating, and the over voltage will kill the μP. If you remove the BT module, you need to add a resistor to simulate the load. Possibly, add a 0.1 μF capacitor between the IN and GND of the regulator. These regulators are a clone of the 78L3V3 from the '70s, no-one updated the masks. They oscillate without a load, or if there is any inductance between the power source and the IN terminal.

I haven't a clue what I've just witnessed. Parkside batteries don't have bluetooth in. And why would you need it? Just plug the battery into the strimmer and get on with it...

[@levieleuterio]

The Smart batteries have

[@rbee3936]

@@levieleuterio And they tell your phone that they're out of juice? You notice that yourself when your strimmer slows down and even more so when it stops - no computer app needed there, and most people use both hands with power tools and can't use their phones at the same time, so they know long before they've looked at their phones... Quite pointless and a waste of time...

[@levieleuterio]

​@@rbee3936 You can change the discharge voltage and the max discharge amps. You don't need to use the app when you use the battery

It's like the smartphone companies that advertise AI on their phones. Useless but necessary to keep competition and have something to sell.
