Weird battery charging issues

[Felix le Chat]

Thanks, that's useful to know. Funnily enough, the new battery arrived today. I just tested it in the charging hub (with the other 2 batteries in it too) about an hour ago and all good now

...Broadsword calling Danny boy... Broadsword calling Danny boy... Nice to hear the problem's sorted.

Thanks yes glad it’s sorted. That was a slightly frustrating start to my latest foray into drones (owned a couple of P3’s about 10 years ago).
I can’t fault DJI customer service though. They sent the replacement battery out pretty quickly.

Bummer about the faulty battery, but -on the upside- you gained lots of know how! One more caveat... avoid charging any battery that is still warm/hot. Really shortens the batteries' lifespan. Now that you have fully working 'good one's you're more likely to rotate each equally, and while cool.

Any methoh to cool batteries down faster?

Don't let them get so hot in the first place. Avoid flying in excessive ambient heat and land well before 10% remaining battery. Pushing batteries completely to exhaustion builds up lots of heat and stresses the battery.

Other than that, putting them in front of a fan in a cooler environment will cool them faster.

Can one put a battery on a shelf in a refrigerator to cool it down faster? Will cooling a battery down at a faster rate like this affect the performance and ilife cycle of the battery?

Placing a battery in a fridge is generally a bad idea.

When you take a cold battery back into room air, moisture can condense inside or on the terminals. LiPo batteries are not designed to be charged below ~10°C (50°F). That runs the risk of damaging the cells. Fridges tend to be humid, which is also not a good thing for electronics.

Best to let them cool at their own rate before trying to push another charge in. As they cool and stand idle, they recover charge... not a massive amount, but significant - the same with the battery in the controller. Start charging a battery that has a stable residual charge in it.

I also don't think refrigerating batteries is a good idea.

Thanks, wasn't aware of potential moisture problem. Guess back to using fan to cool down batteries after each use if I want to use it again while out flying my drone.
