If you don't use your oven, you could charge the battery in there. Or a fireplace. An old grill or old refrigerator in the backyard works.
My gas oven is broken anyway so I could use that, but I prefer to charge my batteries right beside me while I watch TV.
That way I figure that I should see/hear/smell SOMETHING before it FuKin EXPLODES

??
I've got a well built battery with Quality Samsung 50E Cells inside, and I Really Don't Think that they are counterfeit cells.
It's packed Tight inside an aluminum case that is abrasion proof and should take a pretty good hit before it Blows Up.
I have dropped my batteries a couple times (from about a foot) and did no damage.
I charge my batteries manually at 0-3 Amps to whatever voltage I choose, so I choose 51.6 then top up the last three Volts before a ride.
I'm quite confident that I will never "need" a CO2

but I wanna make dry ice

again.
It's been almost 40 years since I made a CO2 snowball.
Remember Fire Extinguishers aren't as dangerous as the person using it.
