- This same basic concept will apply to many laptops. Here I show how I modify the main board to accept a battery pack built from scratch for this verus pro automotive diagnostic scan tool.
Tools I use -
Soldering
Quick 861DW hot air station
Duratech TS-1640 solder iron
Multimeter
RMM760D - can be found under many name badges
Microscope
Luzky Zoom 3.5 - 90x simul-focus single boom stand trinocular stereo microscope
Camera - Lucky Zoom HD 14MP
Oscilloscopes
Siglent SDS 1102CML 100MHz 2CH
Philips PM 3305 35MHz 2CH
Bench supply
Powertech MP-3086 0-30V 3A
TL866II PLUS universal EEPROM programmer
I don't have a clue how you opened the case of that battery so nicely. I am destroying the case on mine. Seems to be welded together
Fantastic work! You have excelled yourself yet again!
Thanks mate, I do surprise myself at times.
@@JonnyFix Genius! From an ordinary bloke trying to do something similar to my laptop (purchased wrong size replacement battery and to late to return). Don't have a technical background or your mad skills to reverse engineer, etc. Comments here at least light up possible path in substituting batteries, the bloke way. A BIG CONGRATS!
@@mevk1 Thanks mate, appreciate it. Hope you figure out a solution to your one!
I've played with 18650 lithium batteries and cheap BMS units, I've never had a problem with making them or the BMS units.
I refurbish them out of old laptop batteries, you yield about 90% of the batteries, meaning only one is generally buggered in a pack.
The main thing I do is charge them first, measure the A/H, I built an 8 way picaxe controlled auto test unit.
You and balance them into packs with the repacker utility on secondlifestorage.com/.
I currently solder them but have built a spot welder (just a bit scared and old to test it yet).
I've built two EBikes (70 batteries each 36V) and modified a mobility scooter into a Golf Board (140 Batteries 24V).
The good thing is it has cost nothing for the batteries just a few dollars and time.
Love your videos
That's awesome, I'd like to make a spot welder as while I've had no problem soldering to the cells I hate to think what the heat is doing to the chemistry especially at the negative end. Thanks!
great video , The ene 128 pin chip (EC or super io) talks to the battery and the charger ic , ene chip use LPC bus to south brige or pch to give the battery state and charge level 👍
I read your comment and Sim's about just replacing the pack and not locking out. I have a spare battery that I could send to you and pay you for your service if you can try replacing the pack and make a video about it. There are a lot of Verus Pros that are now needing the charging cable in order to be used because the batteries are no longer being sold. The current battery in my Verus charges and works for about 20 minutes before it just shuts down unexpectedly without the battery giving a low percent warning; it powers on again but takes just a couple minutes and it shuts off again without warning. Please let me know, thank you!
I missread like - Make your own laptop battery strapon .... - kinda makes sense, but I guess D size would be a bit better ;)
That's brilliant and funny at the same time :-D
I'm with you all the way, i did notice the mosfet trying to burn out that resistor to 3v he he, mistakes creap in even when you think you have drawn the diagram correctly. ( You are not alone, lol ).
i've made daft mistakes and only found out years later, my words were " What the ... hell, how did i miss that?".
You need a circuit to lift a real white flag when the battery wants to surrender ha ha :-D
Maybe a 5 led bargraph chip Lm391? linear scale (in dot mode) could be configured to monitor the battery voltage and light the last led a bit before the battery voltage was terminal lol.
You did really well there, i would have run away screaming :-D
Anyone know how long a standard snap-on verus classic battery should last,three hours or so?
My battery currently lasts just over an hour,i just want to know if its going to be worth buying a new one?Thanks
Sounds like it's almost dead, I'd think at least 5hrs. The new pack I made does 8.
Very well done and video, you have my Sub.
Glad you enjoyed, thanks for watching!
Hi!
Thanks for the video ,, I have a question.. Can I just replace the batteries?
if so, What kind of batteries you have there.. thank you
You can replace the cells they're only 18650 type but you can't at any point in the process allow the voltage to drop on any line from the cells or the pack will lock out. I have tried a few ways but never managed to do it successfully yet. If there is terminal voltage it should be dooable. If the pack is in a state where it doesn't charge and there is no terminal voltage it might be locked already.
Have you tested the fuse? It blows very rarely for serious reasons like if the battery gets too hot. Perhaps the controller had not blocked itself yet. I have a few laptop battery control boards in my stash that I can connect and disconnect battery packs over and over again and they seem to not mind. I read the SMBus and there are no fault flags. To disconnect the pack without throwing an error flag you usually have to start by disconnecting the GND and then all the other cells one by one. Connecting the pack is the other way around. Then you have to activate the controller by briefly connecting (preferably with a resistor) + from the battery pack to the + on the battery out.
By the way, the pack needs to be balanced before connecting it to the control board.
I don't know why but I have had no luck with many packs they all go into lock out. Maybe because it wasn't ground first. Thanks for the info!
@@JonnyFix No problem mate. I think it depends on which cell the controller is powered off of, but I'm not sure. I always disconnect the ground first.
@@JonnyFix Oh, one more thing, many of the TI BQXX... controllers can be reprogrammed or the error flags removed using a $4 CP2112 adapter and BE2WORKS software. Demo version works with BQ.. chips for free. Most of the time flags can be removed even if the controller is not on the list.
@@SinsBird Where was this info 2 months ago HAHA. I swear I looked everywhere XD
Can you make me one
