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!
Ah yes that makes sense! definitely wouldnt want that on a flying bot!
this product could be used just take the LED terminals and input them to the ATD and if the voltage on the ATD is above 1.5 or 2 VDC then have a warning window pop up it will still turn-off the circuit then Product
That might work but would only give a low battery indicator, I was hoping to be able toreadthe battery level and show the battery level so you can see how much time is "left". Do you think that is possible?
sounds like you want a voltage meter attached if you just want the robot to shutdown when the voltage on the battery is to low I wouldnt over complicate things. I am sure there are voltage readers for LiPos per cell but then u get into bigger and bigger circuits that overcrowd ur general need.
Yeah I supposed its not necessary, just a nice to have, I like how my UPS has a desktop gadget that tells me the UPS bat level as well as my iphone etc. But if its a pain I will stick to a straight cut off. I might order that part you suggested as well.
When you say hook the LED input up to the ATD would that just be a digital port on the EZ_b ?
Thanks!
no the EZ-B comes with 8 ATD ports that can read voltage up to 5V. And don't let me decide for you its your robot I am just saying sometimes its better to think easy, just giving you some ideas.
