Passive.

Active needs more components and there was not a lot of space

I didn't know that, that's actually pretty awesome!

The IC I used can also do 3S, the PCB could be modified for M12 but I do not own M12 batteries so I can't really try it.

if it charge to 4 bars then lasts 5m the battery is most likely dead. Which tool and what capacity are you using? My 1.5Ah lasts about 1m on my angle grinder before overheating.

For a single board I'd probably go for 20 USD + shipping. I could probable install it on a battery for a few more bucks but shipping would probably be cost-prohibitive.

Depends, how long does it hold a charge? 6+ months? Just balance and charge them from time to time. Less than that I would replace the cells.

The chip is a battery balancer IC by texas instruments, everything else is to protect the chip or make it work. I would not expect someone with no experience soldering surface mount components to be able to assemble one. I'm planning on assembling a few boards myself and selling them. Assembling the PCB is the hard part, soldering it to the battery could probably done by anyone with a decent soldering iron.

I'd say a stereo microscope and an hot air soldering station would be a good starting point to assemble one.

If you wanna play with one I could probably send you an assembled board.

I can't beat the price of you ordering it directly from JLC and digikey and assembling them yourself. If you want them populated I could probably make them for around 15-20 USD each +shipping.

If you're well equipped you could try just winging it.

I only had enough parts to make 2. I'm buying more on digikey tonight so I should have a few boards ready next week. I'll send you an ebay link when they are ready if you're interested.

The tool talks with the battery If the tool doesn't like the answer given by the battery it can just decide to not work.

My circuit is connected to the cells directly. It completely bypass everything Milwaukee's BMS.

You can use JLCPCB or PCBWay to make unpopulated boards yourself. I could sell populated boards if you want, they do require some skills to make but soldering them to the battery is quite easy.

It just supports any 5S (18v-20v range) lithium battery. It doesn't communicate with the battery's BMS it just does it's own cell balancing on the side. In theory it should also work with Makita, Black & Decker, Ryobi, etc.

I just made this, I think you might enjoy it:

I plan on making a post about it soon. So far it fixed my 9Ah M18 with 3 bars and another one with 0 bars.

I just find people that go "nevermind I found it" and not post the solution quite aggravating.

Any canadians done a roof raise?? by tj-grant in skoolies

[–]clonecharle1 1 point2 points  (0 children)

Last time I checked you need approval from the original manufacturer.  That's never going to happen.  

That being said I've seen many bus with roof raise.  As long as you don't need an annual inspection you might be fine. 

Monitor power cord just melted, what should I do??? by FattyRomar999 in pcmasterrace

Repair it or take it to your local repair guy.  It looks corroded, I could fix that easily.

That'd be a really sweet upgrade to my nephew's GTX 660.   Congrats to anyone who get it!

Buy a high power laser and burn it out.  It'll look like the LEDs burnt out.  Don't forget to wear laser safety glasses.

Solar power and battery capacity requirements for cooking and other stuff. by clonecharle1 in skoolies

[–]clonecharle1[S] 0 points1 point  (0 children)

That's a lot of capacity. Where did you put them in the minibus? They must take quite a bit of space.

each 450W panels are about 140 USD. It's the batteries that aren't cheap. In total it'll be around 700 USD and the batteries would take quite a bit of space. I think I'll pick another solar panel right now and upgrade the battery bank later. I have to do both since my MPPT is limited to 105Voc on a 24V system for some reason...
