The Phoenix Mini 3.7V 380mAh LiPo battery is a compact lithium polymer cell designed for small electronics like drones, mini cameras, and IoT devices. It offers 380mAh capacity, 3.7V output, and a lightweight form factor. Replacements should match voltage, dimensions, and connector type. Always prioritize batteries with built-in protection circuits to prevent overcharging or overheating.
How to Prevent Lithium-Ion Battery Fires and Explosions
What Devices Use the Phoenix Mini 3.7V 380mAh LiPo Battery?
This battery powers compact gadgets requiring low-weight energy solutions. Common applications include mini drones (e.g., Tiny Whoop models), wearable health monitors, mini RC cars, and smart home sensors. Its 38mm x 20mm x 8mm size fits space-constrained devices. Always verify terminal alignment (JST-PH2 connectors are common) before purchasing replacements.
How to Safely Replace a Phoenix Mini LiPo Battery?
1) Power off device. 2) Disconnect old battery using plastic tweezers. 3) Check polarity markings. 4) Install new battery with matching connector orientation. 5) Secure with adhesive pads. Never puncture swollen cells. Use a LiPo-safe fireproof bag during storage. Charging should be done with a 0.2C-0.5C rated charger (76mA-190mA for 380mAh capacity).
When handling replacements, always wear anti-static gloves to prevent electrostatic discharge. The JST-PH2 connector requires precise alignment – reversing polarity can instantly damage devices. For installations in vibration-prone devices like drones, consider adding a strain relief loop in the wiring. A proper replacement sequence should include:
| Tool | Purpose |
|---|---|
| ESD Tweezers | Safe connector handling |
| Digital Calipers | Verify battery dimensions |
| Insulation Tape | Secure loose wires |
Why Does Temperature Affect Phoenix Mini Battery Performance?
LiPo batteries lose 20-30% capacity below 0°C and risk thermal runaway above 60°C. Cold temperatures increase internal resistance, reducing voltage stability. High heat accelerates electrolyte degradation. For optimal Phoenix Mini operation, maintain 15-25°C ambient temperatures. Store at 40-60% charge in climate-controlled environments to prevent capacity fade.
Which Charging Practices Extend Battery Lifespan?
1) Avoid full discharges – recharge at 20% remaining. 2) Use balance charging weekly. 3) Limit charge rate to 0.7C max (266mA). 4) Never leave on charger >24hrs. 5) Store at 3.8V/cell. Implementing these steps can achieve 300-500 cycles vs. 200 cycles with improper care. Voltage should never exceed 4.25V or drop below 3V.
Advanced users should consider using smart chargers with capacity logging. The ideal charging profile involves three phases: bulk charge (constant current), absorption (constant voltage), and float maintenance. For the 380mAh model:
| Charge Rate | Time | Cycle Impact |
|---|---|---|
| 0.5C (190mA) | 120 mins | Optimal lifespan |
| 1C (380mA) | 70 mins | 15% faster degradation |
“Many users overlook the impact of partial charging cycles. Our lab tests show charging Phoenix Mini batteries from 30% to 80% instead of 0-100% can triple cycle life. The 3.7V nominal chemistry is particularly sensitive to high-voltage stress.”

FAQ
- Can I use a higher mAh battery as replacement?
- Only if physical dimensions match. A 500mAh battery may provide longer runtime but could overstress charging circuits not rated for higher capacity. Check device specifications for max supported capacity.
- How to check battery authenticity?
- Genuine Phoenix Mini batteries have laser-etched QR codes on the foil pouch. Scan with manufacturer’s app to verify. Counterfeits often use printed labels and lack overcurrent protection PCBs.
- Is overnight charging safe?
- Not recommended. Use chargers with auto-cutoff at 4.2V±0.05V. Continuous trickle charging degrades LiPo cells. A 380mAh battery typically charges fully in 1.5-2 hours at 0.5C rate.
