If you want to just test voltage (and not capacity) a standard volt meter will suffice. If you are wanting to test rechargable batteries for their capacity then you will want to cycle them with recordable device that will count the AmpHour (or miliamphour) for discharge and then charge. For this I use an opus3100 tester. Or RC battery charger /discharger
Personally I love sho-goo. It holds great. And is also removable if needed. (Twist hard and it will come off then you can peel the stuff off). Stays flexible when cured and just use tape to get it to stay while curing
it's easier to police poachers if no one is out fishing for them. just being lazy
That's not even the question. You need the back story. ie. how "known" to police were the victim and perp , how busy was the police at that time, and why did they not attend. those are the questions that need answering. which is now in the SIU's hands
Do not buy anything from Acer.
Locally the prices jumped from 1:52 a litre to $1.76. So how about no
they are not designed to be User changeable. I'm sure you can brute force your way into it but it also may be glued shut
Looks like you are well on your way for a safe battery. Been playing with these types of cells for years now and I use really thin tinned copper wire to act as a fuse. The real issue you will see if you use "heaters". These are known cell types typically red Sanyo's that over time when fully charged start to self discharge which generates heat. Mitigate that issue and they are really stable. I have even direct shorted a 80p pack by accident and all it did was blow the fuses. Anytime you are building this stuff yourself you need to keep an eye on it either with some software that tracks each cell (generally a cell means one parallel set of cells) for voltage and current usage. Also if your bms can record how much any cell balances can show issues before they become a hazard.
My biggest recommendation is to put it outside away from your house. This is the easiest and safest way of protecting your house. Barring the ability to do that a good metal enclosure with exhaust to the outside is a must
If you call me out to look at an issue, you will just stand up when I get there. I have walked out of the President's office for this. We are so short staffed that you do not have the ability to waste my time.
