Part 8. FAQs

1. What does “4S” mean in a LiPo battery?

“4S” means the battery has 4 cells connected in series, producing a nominal voltage of 14.8V. Each cell provides about 3.7V.

2. Is a higher mAh always better in a 4S LiPo battery?

Not always. Higher mAh means longer runtime but also more weight, which can reduce performance in drones and racing RC cars.

3. What is the difference between 4S LiPo and 4 cell Li-ion batteries?

LiPo batteries are lighter and deliver higher discharge rates, while Li-ion batteries usually offer longer lifespan but lower power output.

4. Why does my 4S LiPo battery puff up?

Battery swelling usually happens due to overcharging, over-discharging, or aging cells. A puffed LiPo should not be used.

5. How do I know if my 4S LiPo battery is bad?

Common signs include:

Rapid voltage drop
Swelling or deformation
Excessive heat during use
Unbalanced cell readings

6. Can I increase runtime by connecting two 4S LiPo batteries?

Yes, but it depends on wiring:
Parallel connection = more capacity (longer runtime)
Series connection = higher voltage (not usually needed for 4S systems)
