Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Save on Capacitors
I recently bought these for a six-capacitor jump pack I made. I charged the pack with a standard, 10 amp car battery charger and (not sure why) it overcharged the pack. On each of the protection boards, I noticed a red LED come on one by one until all six had a red light on. When I checked the voltage of the entire pack it read 16.3 volts, which is 1/10th of a volt under the limit! I realized that when the LED light comes on, it means the board has stopped putting charge into the cell, which is exactly what it is supposed to do. I didn't even know they had lights on them or even how they function as there were no instructions, but I don't care...they worked, and I'd buy them again. Thank You

There are two kinds of capacitor protection boards of this form. I have six of the kind shown in the photo but two have failed so I ordered two replacements taking care to choose the same kind. The two delivered items were not the same kind.
