I have a battery operated tab welder and the battery does not have enough current for the battery tab welder because after about 30 welded it does not have the same current output it voltage has gone down by at least 0.500 volts or maybe a more than that
I can fit 21700 battery cells in the enclosure it is very tight fit for four of them that are 35 amp high current capacity 35X4=140 high current output this should work a lot better than what is installed right now
I tested the battery cells there are installed right now and they are testing good with no issues that I... -
I have a cheap action camera with an annoying trait, every time I change batteries the date & time gets reset and I have to set it again.
To solve this problem I want to add a small internal battery inside it which will keep supplying power to the camera for a while while I change batteries so the date & time is retained.
I have opened the camera and I think there is enough room to add something inside to accomplish this:
The camera is powered by a 3.7V nominal single cell lithium ion battery.
So I need to connect another battery in... -

This iPad was working fine except the battery was not holding charge for more than 40 minutes. I replaced it with a new battery. I haven't glued the battery yet, just inserted it into the slot and held it with battery screw.
The iPad was powered on with the new battery and I am getting white screen with Apple logo for about 10 seconds, then the screen turns dark. It then cycles like this forever.
I know the battery is working because the iPad continues to boot loop without the charger until it depletes to 0% and the message displays I need to plug in the charger.
