Good battery with it's own power switch

I had purchased this to use as the power source for a quad-legged spider robot I had built. The servo motors would never work correctly. I measured the battery output at 7.4 volts. I charged it overnight and checked again.It was still measuring 7.4 volts. I cannot use this battery for its intended purpose. It wont even power a 12 to 5 buck converter to charge my smartphone. The buck converter cycles on and off because the battery voltage is too low,

Although it worked for the time I used it, I swapped it out for a DIY battery because this just has 3 mobile phone batteries in series with no protection circuit and were rated for lower mah than advertised. It's just large because of some foam padding they put in it.

Good batteries. Hold charge for long time being unused. I use them for emergency lighting. I.E. LED 12 volt track lights adapted with magnet bases for my truck.

These batteries are poorly made and a scam don't get them.Cell phone batteries mismatch and underrated no protection circuitry meaning that at any point it can overcharge and Catch Fire

Good product. Better than expected. Would buy again.

Stopped working a few months after I got it. It won't charge, and when it did work, it discharged relatively quickly.

The charger was a 240vac plug and the pictures show a 120vac
