Battery Detector with Polymer Lithium Ion 1050mAh 3.7V
Introduction
Battery Detector with Polymer Lithium Ion 1050mAh 3.8V contains two items: a 1050 mAh lithium-ion battery and a battery power detector to measure the power remain in a li-ion battery.
The li-ion battery is very slim, light and cost effective. It output 3.7 V voltage(nominal). You can also charge it with a specialized charger which has maximum input current 1050 mA and maximum input voltage 4.2V. This battery comes with pre-attached JST 2.0 connector which is handy to click in and out. It also has built-in overcurrent protection to protect against output short circuit. Although, please still take caution and do not abuse the battery in usage. Never charge or use it unattended.
The battery power detector can detect the input voltage range of 3–4.2 volts. There are three JST sockets (JST 1.0, JST 2.0 and JST 2.0) and two battery-soldering pads will adapt to those batteries with a different connector. As you connect a battery to this battery power detector, the on-board four LEDs will indicate remaining power in percentage (0–25%, 26–50%, 51–75%, 76–100%). Another LED will be on if you plug the connector of battery in the wrong way.
Notes
1. There is only one battery reliable to be tested at the same time.
2. It will damage this battery power detector as the input voltage is above 9 volts.
3. Never use the battery when it is being charged.
