hello everyone, I am attempting to replace a battery on a toy light saber for a friend. I finally found two batteries that actually fit in the hilt.
The original battery is a 3.7v 700mah lithium ion cell charged through a barrel plug in the hilt, via cable into any 5V usb type A slot.
the only replacement batteries I could find are 3.7v 750mah batteries and when they are connected, a small component on the edge of the board and a screw post (to secure the board inside the hilt), get very hot. I figured that the board could must be using the hilt as a heatsink since it's milled aluminum, but the components make a lot of heat while OFF! the battery doesn't seem to get hot, but I haven't left it connected for more that 10 or 15 minutes out of fear of burning out a component.
Could the 50mah bump on these batteries be causing this issue? does the thickness of the wires from the batteries matter? they are slightly different from each other.
I'll add some photos if necessary
