abstract mantle Mar 31, 2023, 7:27 PM

grim ledge Mar 31, 2023, 7:27 PM

#

1 sec

abstract mantle Mar 31, 2023, 7:27 PM

#

what voltage are you expecting it to show up at?

grim ledge Mar 31, 2023, 7:27 PM

#

3.25

#

but for the test i put 4.20

abstract mantle Mar 31, 2023, 7:28 PM

#

fly one down to around 3.3 and then send a picture

#

also i wouldnt fly under 3.3

#

i land at around 3.4

grim ledge Mar 31, 2023, 7:30 PM

#

okay so i should put the warning at?

#

wait maybe everything is alright i put it so the low battery text would appear at 4.20 and the battery was 4.06 and its said low battery!

grim ledge Mar 31, 2023, 7:36 PM

#

abstract mantle i land at around 3.4

so i think everything is alright.
but should i change any setting here?

abstract mantle Mar 31, 2023, 7:37 PM

#

change minimum cell voltage to 3.4

#

you really shouldnt fly under 3.3 and 3.4 is what i land at because it gives a little bit of time just incase

grim ledge Mar 31, 2023, 7:41 PM

#

and what to put the warning?

#

that's what betaflight webstie says:

abstract mantle Mar 31, 2023, 7:41 PM

#

dude

#

put minimum cell voltage at 3.3

grim ledge Mar 31, 2023, 7:41 PM

#

okay

abstract mantle Mar 31, 2023, 7:41 PM

#

and warning at 3.6

#

if you fly them to low the batteries break and you cant use them anymore

grim ledge Mar 31, 2023, 7:42 PM

#

okay

abstract mantle Mar 31, 2023, 7:42 PM

abstract mantle and have a chance of exploding/fire

Draining lipos too far definitely damages them, but isn't going to start a fire

#

Dead shorts, over charging, or cell puncture can start fires though

#

@grim ledge have you read Oscar Liang or Vitroid's lipo safety guides?

grim ledge Mar 31, 2023, 7:46 PM

#

no

fervent mesa Mar 31, 2023, 8:11 PM

#

Nothing, it'll just stop charging at 4.2V instead of 4.35V

#

Just means you won't get the rated mAh from the pack, because you'll be starting at 85% capacity

grim ledge Mar 31, 2023, 8:16 PM

#

mhm...
i dont know, i got an GNB battery that on it 3.8V (nominal voltage) , and there is also a text: HV 4.35V so i dont know should i chage it to 4.35V or 4.20V

fervent mesa Mar 31, 2023, 8:19 PM

#

It is rated to charge to 4.35V
