So last night I left my LiPo battery connectd to my bot with the lights on! Beign the first time ive used LiPo batteries I didnt realize that you cannot drain them past a minimum voltage or they wont recharge anymore.
I recovered the battery by using the Nimh setting on my charger to bring the voltage back up to 12v then I was able to balance charge again.
Is there some kind of voltage detection relay switch I can get to automatically cut power if the voltage drops below a certain amount so this doesnt happen again?
Thanks!
maybe some like this
this
or this
hope that helps
Thanks that helps! Im going to try to find a supplier in Canada. Amazon says not allowed because they hate canada. and the other link is florida which I might try anyway if I can't find a canadian supplier.
For anyone else who looks for this item I found a candian supplier and have ordered one. will report back how it works.

depending on your application you might want to use a LiPo alarm instead of a cutoff circuit.
Im hoping I can get a signal back from the cutoff alarm that will let me alert the user via software or speech synth. Even nicer would be to also have a way to read the battery level from the balance charging plug.
u might be able to hack a LiPo alarm and remove the alarm buzzer and have the terminals go to the ADC of the EZ-B and have a script that alerts the user in ARC that the voltage is above so much, when the buzzer would be set off.
Thats a good plan but Im hoping I can probably do that with the cut off as well, but I am thinking its alot safer to use a cut off since a buzzer wont do any good if I dont hear it. like if I leave my robot on and go to work, I would still come home to a dead lipo battery.
this is true but like I said it depends on the application I made a QUAD that flies so a shutoff could crash the craft.
