Hi again fellow roboteers,
I’ve looked up the forums and the dimension engineerings documentations and did not find a clear enough answer to my question.
They say, for the sabertooth 2x5 at the least, that there’s a function called “lithium cutoff” which prevents a lithium battery from discharging below 3V since it damages the battery and at some point it won’t be able to be recharged ever.
But on the Tri-Track page, you (Lynxmotion) suggest these batteries and charger:
batt: lynxmotion.com/p-727-120-volt-ni-mh-2800mah-battery-pack.aspx
Charger: lynxmotion.com/p-602-60-12vdc-ni-cd-ni-mh-universal-smart-charger.aspx
They look neat for the price and all. I will most probably use that since I’m not verse in batteries except for their nominal values (Volts/mAh). So I don’t know which “chemestry” is more damageable or whatever… So here I go:
First: I guess not, but can I use the sabertooth “lithium cut-off” with the Ni-mh batteries? (maybe they react the same or something?)
If I can, is there some adaptation to be made?
If not, I guess I should read the voltage all the time with an ADC on my MCU and below a certain point cut the power or raise an alarm.
Now, sorry for the dumb question, but the battery and charger is the last thing I need to buy to make start using it. I do have a recycled DC power supply, but it seems it’s not good to use that without a battery in parallel.
Thank you very much,
Alex
