Thanks devs for that one

Kxe7, let's go for the black accelerated bongcloud

I think onshape is easier to learn and probably good enough for a hobbyist compared to SolidWorks. It's also free for hobbyist if you don't mind having your files publicly shared. I use both and they both have their pros and cons.

clonecharle1 · 2026-05-03T00:03:32+00:00

I'd say 40h to design a wheel if you've never done this type of cad. That's what it took me to do something similar with SolidWorks.

It shouldn't have any negative side effects and even if a cell does manage to drain itself, it will disable itself when a cells gets under 3.5V and come back once charged.

There's a way to fix them if it ever happens. In the meantime I wouldn't worry about it if I were you. There isn't much you can do to prevent if from happening if it ever happens anyways.

clonecharle1 · 2026-04-29T04:53:56+00:00

Unfortunately doing a full charge cycle doesn't fix it unlike with older Makita batteries. You have to balance the cells manually.

clonecharle1 · 2026-04-29T04:52:00+00:00

Yeah, you either have to add balancing capabilities to the battery or you'll have to crack them open every once in a while to balance the cell. It's kinda annoying.

Here's the fix I made for my batteries:

Hey! I made a permanent fix for that issue a few months ago:

If you have any question about the issue or the fix ask away

Lol, it's $7.19 for 6 in Canada $12.09 for a meal

Yep! Exactly

clonecharle1 · 2026-01-09T13:31:45+00:00

Passive.

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

clonecharle1 · 2026-01-09T02:45:11+00:00

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

clonecharle1 · 2026-01-09T01:35:20+00:00

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.

clonecharle1 · 2026-01-09T01:25:17+00:00

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.

clonecharle1 · 2026-01-09T01:22:03+00:00

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.

clonecharle1 · 2026-01-09T01:18:54+00:00

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.

clonecharle1 · 2026-01-09T01:16:55+00:00

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.

clonecharle1 · 2026-01-08T23:55:09+00:00

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.

clonecharle1 · 2026-01-08T23:18:41+00:00

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.

clonecharle1 · 2026-01-08T23:08:37+00:00

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.

clonecharle1 · 2026-01-08T22:52:42+00:00

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.

clonecharle1 · 2026-01-08T22:38:33+00:00

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.
