I didn’t have my charger connected but I connected the shutter motor power while I was installing the track. Of course I left it connected and now the battery is dead.
Babak gave me the part number to buy a new battery but I was wondering if anybody had any luck recovering a dead battery with a beefier charger or something.
I know I’m Cheap but before I go spend $50 I’d like to know. Also I figure in case I have a shutter close due to bad weather and the dome doesn’t park, won’t I have the same problem?
I have the dakota lithium 12v battery in my shutter, along with a dfrobot leonardo xbee board for the controller. So it turns out you can wake up a discharged battery by simply powering the leonardo with it's dc input jack or usb - the usb is accessible but if you unscrew the two screws on the right and pull the cover out you can also get quick access to the dc jack. It only takes a second to get it going and have the included BMS start charging again. I'm actually kind of surprised no one else found this, maybe the dakota wasn't in deep sleep yet but cut off the leonardo?
Nice! Thanks fot the hint Steven!
Hey, I just posted a battery reset method I got from Dakota Lithium. It located in the forum here: https://www.youtube.com/watch?v=0Cd-86MrP3c

The key thing is when shutter closes have it land on tabs. All will be well then. Humm.. that $10 circuit might be a op amp as comparitor running a relay?? I could use one.. Also!! I set my "low battery" value in driver as 10.2V because when it is moving it can sag a bit. Indeed 10.0 is totally dead for a 12V - ya do not really want to go there unless by accident.
Good luck!! Ron
Thanks guys. I have a better charger and I hope to recover this one. If not I’ll try walmart.
Also, I thought something like this might exist but would there be anything stupid about connecting a little switch in line with the battery that prevents it from discharging below 10V? I‘m Looking online and they are like $10. Surely that’s worth it unless it would prevent the shutter from closing if needed.
The dome park thing to get onto tabs is a great thing about ACP. THere you have what is called a weather script which does whatever you wish. Mine starts dome homing and then starts shutter closing; finally, mount is parked. Basically if the dome was at 180 (home is at 0) it arrives there about 4 sec before shutter is fully closed.

I also been able to resurrect my Shutter battery using this charger instead of the orange battery maintainer that comes with the dome: Genius G1100 charger: NOCO Genius G1100 6V/12V 1.1 Amp Battery Charger and Maintainer https://www.amazon.ca/dp/B004LX3AXQ/ref=cm_sw_r_cp_api_i_BBYWCbB85TP1F
Go to Walmart.com. I got a spare 9Ah exact same size for less than $50. I also replaced the charger with a LeicesterCN at amazom. Has more ommph but still safe to leave on battery 24/7.
Also! I killed my battery just like you did once. It will recharge just fine if you have a bigger charger. I just connected my other big charger and set it for a 2A rate and all was well. You may lose a few discharge/charge cycles because of it getting killed but should work OK.
Good luck!
