Use safety circuits in battery packs to check voltage and heat. This makes batteries safer and stops them from overheating. Charge batteries the right way by not overcharging them. Keep the charge under 4.20V per cell to make them last longer and avoid short circuits.
[pdf] For a standard 3.7V lithium-ion cell, voltages under 3.0V indicate deep discharge. Prolonged operation below this threshold degrades capacity, increases internal resistance, and may cause catastrophic failure.
[pdf] Keep lithium batteries within the ideal temperature range of 15°C to 40°C to ensure safety, maintain performance, and extend lifespan. Use a battery management system (BMS) to monitor temperatures in real time and control cooling or heating to prevent damage and thermal runaway.
