FAQ
Q1: How do I connect this battery to my device?
It comes with bare wire leads, so you can solder directly to your circuit or attach your own connector.
Q2: What type of charger should I use?
Use a LiPo charger designed for single-cell 3.7 V batteries. It must support constant-current/constant-voltage charging and stop at 4.2 V.
Q3: How long will it run my device?
Runtime depends on the current draw. Example: at 50 mA load, expect around 4 hours (200 ÷ 50).
Q4: Can I fully discharge it?
No — avoid discharging below ~3.0 V, as it can damage the battery permanently.
Q5: How many times can I recharge it?
With proper care, expect 300–500 charge cycles.
