My effort is a bit timid. Made a couple of trestles from some free wood.
But then, I played with this !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Made a rough and ready little steel ramp from 100x50 box section. It's to allow a 1 tonne bobcat to drive into the back of a 20yd skip as it will only just fit into a narrow site entrance so no way to load over the side as usual. It'll have a 1" plywood top put on it tomorrow which is plenty strong enough for the job. The bobcat is 900mm wide this is 1350 overall. Doesn't need a runner in the middle coz if you have a wheel ther ethe other wheel is off the side.
And the exception is... Ryobi, which has a OZ8940ATN BMS on a circuit board in the pack itself.
Today I earned some much needed wife credits, spa has been blowing out one of the fancy rotojet thingies because its little plastic tabs have gone weak, and they are difficult to get hold of. I'm told theyre cmp jet bases and have just gone out of production hence everything left in stock now has a rarety price tag...
So scanned the ejected one, fixed the tab in cad, 3dp in resin and voila, beer in spa and happy wife. If it breaks because resin printing is weak, I'll do one in abs or nylon.

At least the Milwaukee statement that they've got over discharge protection has been proven as bull poop (this is me as a Milwaukee user). Fairly sure the majority of the others have also been shown to be false statements.Cordless Tool Battery Over-Discharge Protection Table

That video is says they do have over discharge protection circuits that prevents the per cell voltage going below 2.0v. This is lower than the 2.5v the video author thinks it should be, I don’t know the validity of that. He also mentions in the video that 2.0v minimum is within the Samsung battery cell spec for certain types.
Dewalt has nothing.
Lithium batteries are most likely to catch fire, catastrophically, when empty.

They have monitoring but no actual protection - that is down to the tool. Plug something dumb into the battery and you WILL overdischarge it. The BMS only signals the tool to tell it there's a fault, it doesn't actually cut the power.
From the design perspective the tool already has to have a big MOSFET in there to control the tool so why introduce another lossy component in the battery? It's extra cost and less efficient and they get around it by saying you should only use their tools with their batteries which they know and have tested to work.

Interesting watch. I've never tested the cell voltage when run down instead just sticking it back on a charger. Thinking of what batteries I have and it's a 4ah, 6x 5ah, a 9ah (not that rare) and a Forge 8ah, no M18 High Outputs but I do have in M12. Not one of my batteries has ever died and most are over 5 years old. The tool just stops when the battery is flat and not the slow grinding to halt like it shows on the video and then checking the battery I get the flashing 1 bar to confirm it's flat before charging (rapid chargers), so they are been electronically stopped rather than running out of power. I've recently been sanding the walls and wood work with the 125mm RO sander and multitool which are power-hungry and 5ah batteries are lasting around 25 minutes so battery off and put on charge with another charged battery ready to go with just enough rest in doing so for my hands to stop tingling and the pad to cool down. Not sure if I'm just lucky or there is something I'm doing that is prolonging the batteries.
It was good to hear that the battery adapters are a risk to battery life as I'm a firm believer in using the manufacturers battery designed for their tools.

I'm not sure if it's applicable to all technologies but I'm fairly sure it's lithium ion that's dangerous to over discharge, over charge, over heat and do pretty much anything else with. By dangerous I mean fire starting dangerous. That's why most batteries are shipped at 50% charge.
The adapters can be used but their limitations need to be noted. For example I've got one for a soldering iron for an M18 battery but I keep an eye on the charge level, it's only 9W so will last ages. I will build a protection circuit at some point but need to finish the housings first.

The single sided spot welder looks interesting, is it an add on to a machine or a whole new bit of kit?
