how safe is my 20v / 1.5amp battery?
can it cause a shock?
>>
No, unless you somehow stick your tounge across the battery terminals.
>>
>>2683899
they're tucked in but sort of exposed. i just want to know how careful i need to be going near the connectors with my hands.
>>
>>2683900
Maybe a small shock if your hands are covered in saltwater, but not much, and it would have to be like one finger across the two terminals.
>>
>>2683901
but isn't 1.5amp too high? considering 20ma is enough to shock you.

Pic related is the same type of shit with exposed terminals and there’s no shock. I’m touching it right now.

Try not to short it out with anything metal
>>
>>2683903
No. And you misunderstand volts-amps-Ah(amp-hour).

1.5Ah is the capacity, meaning it can deliver 1.5 amps for 1 hour or 1 amp for 1.5 hours.

That pack probably puts out 20A+ worth of current, which is pretty good, but only at ~18V which won’t really shock human skin. High voltage is what will actually go through you, and high voltage plus lots of amps will kill ya, but the voltage has to be high for the amps to actually make it through.

I’m not an electrical engineer though

>>2683905
thank you

>>2683904
he bought a RYOBI! everyone get poo on stick and POKE him with it!
>>
>>2683910
Haters gonna hate on a smart financial decision and a super broad homeowner friendly tool lineup!
>>
I'd buy Ryobi before Ridgid. Straight up with no malice towards either brand (I use Kobalt lmfao)
>>
>>2683917
I would probably get Ryobi too given their current lineup, but when I bought into Ridgid, they had brushless stuff and I don’t think Ryobi had released any of the HP stuff.

They have some dope stuff coming out soon, an 18V handheld tile saw with a little water tank on top, USB mini ratchet and soldering pen, a cooler, plus pic related. By far the best lineup for homeowners and hobbyists and even if you have Milwaukee at the job for 40hrs a week, there’s a ton of Ryobi you might want for home.

I may buy picrel one of these days too. I love my $70 Gooloo jumper brick, it’s a beast, but I don’t love having all those Chinesium lithium pouches sitting in the car all summer. I would prefer a Ridgid jumper pack because I often have my 1/2” impact in the car with a 6.0 battery for road trips anyway.

Ryobi is also going to drop 8.0 and 12.0 18V batteries soon. Need some of those for the outdoor power tools, 8.0 on the chainsaw would be sweet.
>>
>>2683905
You are right about the electrical stuff.

>>2683903
Consider a car battery. It can easily give out 300 amps at 12V, yet if you grab both terminals with your hands, you will not feel a thing unless your hands are wet or full of cuts.
>>
>>2683937
> chinese li-ons sitting in hot car
Heh… good point!!!
My old lead acid jumper has peetered out after 10+ years, i was going to go li-ion as the new hotness, but now I’m not.
Plus, where I live it can get to -40 so, well, li-ion isn’t going to be an option.

They teach you this stuff in primary school.
>>
>>2683896
Not really, the only thing you can possibly risk is a lithium fire.
>>
is plebbit down or something? what is this shit?
>>
>>2683896
The dielectric breakdown voltage (the voltage at which something stops being an electrical insulator and becomes an electrical conductor) of skin is about 45VAC and 55VDC.
Like other anons have said, don't stick your tongue across the terminals. Your skin will protect you against anything roughly under 40V.
>>
>>2683936
>>2683937
Why did I have to scroll past this? I just bought a bunch of shit, now I want even more shit.
>>
>>2684091
I don’t think either of them are out yet. Check out some of the USB stuff coming, that little soldering pen looks cool. And the wet 5’” tile saw, I don’t need it but I want it.

I’m curious about this cooler, for $500, maybe it’s built like that Makita one with a compressor in there.
>>
>>2684097
This thing goes to -4F, has a 12V car adapter and a 120V adapter. Holy shit.
>>
>>2684097
>>2684099
The Lithium USB stuff was the shit I just bought. The Heat Pen is already available at Home Depot, but I didn't see the Jump Starter.
As for the cooler, the price might be justified since it seems to suggest it will also come with two 9AH batteries.
