Number of Items: 1
NOT 3.7Vas advertised, tested at 4.15V even after draining the top charge from the battery after the initial charge. the quality is very bad due to the voltage, charge rate is horrible as is the battery life. not 5200mah as advertised, closer to 3500 mah. horrible value when your project doesnt work and you have to spend time troubleshooting battery output voltage. ... show more
