Could be many reasons, super depending on the dynamics of your friend group but in mine I find when things are looking up for my others can be feeling of jealousy can seem like they are being competitive. If you have examples (as anonymous as possible) just to gauge from?

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

The date is immaterial, but it will be a Monday. the Mondayiest of Mondays
