Using the Wild Thumper controller to charge large (10 ah) NiMH battery
March 5, 2013
I've recently upgraded the battery on my Wild Thumper and I wanted to get advice and warnings on charging a larger pack.
The battery fits snugly into the thumper chasis base, and seems like about as much power as I can get without moving to LiPo.
I'd like to be confident in letting the battery sit charging unattended.
If the charging circuit is rated at 2 amps should I assume that a depleted battery will take 5 hours to charge?
Since the default code monitors the voltage repeatedly every second and cuts out if it hasn't changed in 5 minutes, can I assume that is appropriate for this large pack as well? Or should I increase that timeout?
The docs say "The battery monitoring circuit will report a value of approximately 65 for every volt measured across the
battery." Can this be modified? Should I be worried if I'm seeing values like 570? ( ~ 8.8 v)
Thanks in advance!
