Tuning Red Wolf eating batteries

Jump to latest Follow Reply
Are you using a Heliboard ? How much time to get the low battery sign? Should be quite a while with the GCU2 board . 

The GCU2 hasn't been a problem for running batteries down that I've seen. The newest software may allow long enough timeouts to be a problem, but I've no experience there. With the HB, I tend to recharge when it gets below 11.5 so I don't kill more batteries . They SHOULD be ok down to 10 v but I'm up to 3 unrecoverables now so trying not to kill more.

Coming from the RC Hobby world, if it's a 3 cell lipo, I would not run the battery below 11.1v. That is the absolute lowest you should really be going for a low draw application like this. If the low battery sign is not going off until 10v...that's no good at all.

Going down to 10v will most likely result in damaged/bad cells which it sounds like is what you're seeing. Lipos have a better chance of going up in flames when attempting to charge a battery with a bad/damaged cell. I know a guy that burned his house down charging lipos for fpv racing drones. I've also had a couple drones turn into fireballs when I was pushing them on lipos that weren't healthy. 

There are some tricks to see if you can revitalize a cell...but generally not recommended, especially since these sit next to high pressure air sources.

Thanks for all the input. I did have the aftermarket board in it and was at 11v. Then I put the daystate one back in and was shooting fine, then got the low battery warning. Testing then it was about 9.5 to 10v. Using the charger, it showed it was charging and fully charged, but the voltage never changed.

I am thinking that I cannot use the batteries until I get a low voltage reading with the OEM board as by then it is too late.
