⚠️ Usage Notes & Precautions
To maximize performance and safety:
1️⃣ Avoid High Temperatures: Exposure above 60°C or direct sunlight may cause swelling or deformation.
2️⃣ For Low-Power Use Only: Capacity is modest, best suited for low-consumption electronics, not for motorized or high-drain applications.
3️⃣ Proper Storage: When stored long-term, keep charge between 40–60% (≈3.7–3.8V) and recharge every 3 months to prevent deep discharge.
4️⃣ Avoid Overcharge/Over-discharge: Use appropriate chargers and protection circuits to extend battery lifespan.
❓ FAQ – Frequently Asked Questions
Q1: What charging current is recommended for the 501230 battery?
A: The recommended charging current is 0.2–1C (around 26–130mA) for optimal longevity. Higher currents can shorten the battery’s cycle life or cause overheating.
Q2: Can I connect multiple 501230 batteries in parallel for higher capacity?
A: Yes, parallel connection is possible if all batteries are identical in voltage, capacity, and charge level. Use proper balancing and protective circuits to ensure safety.
Q3: What should I do if the voltage drops below 3.0V?
A: Stop discharging immediately and recharge as soon as possible. Deep discharge below 2.5V can lead to irreversible capacity loss or internal short circuits.
Q4: What happens if the LiPo battery swells?
A: Swelling may occur if exposed to high temperatures or overcharging. Immediately stop using and dispose of the battery safely following local e-waste guidelines.
