Useful and easy to comprehend - thanks for supporting your work using practical examples.

Excellent video. And thanks for not mentioning the salt water bath for disposing batteries! 😀

Great material! I feel like I truly understand batteries now! Thanks.

Thank you very much for posting this well done video. I have a follow up question. Charge rate. I own many Pulse Ultra LiPo batteries (standard LiPo, not the HV versions) in the 45C to 50C range. They all state I can charge them up to 5C rate. I generally balance charge at 2C charge rate. In my experience, balance charging at 3C charge saves about 4min to 5min (in real life) compared to 2C balance charge rate. Although I have balance charged at 3C for testing purposes, I have been hesitant to adopt charging at 3C "routinely" out of concern that I would be "significantly" decreasing overall potential charge/discharge cycles and degrading the batteries faster compared to charging at a more conservative 2C charge rate. Is there a significant acceleration in battery degradation and/or significant decrease in number of useful charge/discharge cycles when balance charging at 3C compared to slower charging at 2C?

In my experience and research, no there isn't. You're pretty safe up to 3C I've found.

Very interesting :)

3.0v per cell discharge is very extreme. The true 0% SOC is 3.3 volts. Not 3.0 volts. 3.0v per cell sounds like a maximum allowed voltage sag number.
