P4P battery hub

Wondering if I’m using this correctly to discharge my batteries. The manual says if bats are charged that an external power source is not needed. I have the switch on storage and I put my bats on it(3). It turns the batteries on, the lites are flashing blue. They’ve been on there almost 6 hrs and they’re still fully charged. Am I doing something wrong?

You are doing it right, but a discharge to around 60% can take 24 hours.As long as the lights are flashing blue, it keeps discharging. It turns the battery off when it has finished discharging.

 

[Rbei312]

Yup. It’s been about 8 hrs now and one lite is flashing on all of them. So they’re down to 75%. That’s good. Just so I know it’s working. Very important to storage charge batteries. They’ll last a long time if you treat them right. I have quite a few fpv racing quads and I always maintain those batteries the same way. I’ve lost very few batteries over the last 6 years. Thanx for the responses.

Is there a reason that you're not letting them discharge automatically at the set days? Mine are normally set at 5 days unless I'm flying often and I will set them for 10 days. Hub not necessary.

 

[Rbei312]

No reason. I haven’t tried that yet but I was going to go in and change that limit but think it’s default is 10 days. Actually, leaving the batteries fully charged for 10 days probably isn’t good for them.

I usually set my auto discharge at 3 days. Works for me. If I prepare for a shoot day before, maybe not use all the batteries,I know the unused ones start discharging on day 3.

 

[Rbei312]

So when the batteries discharge on their own do they turn on? Is it ok to leave them in the case or do they generate heat when they discharge?

 

[jephoto]

They do not turn on. Safe to leave in case. They just quietly & slowly discharge to about 50-60%. Takes a few days to do so.
