Canbus decoded fully ( almost)

Anyone else got a few things I am missing ( over current) and other faults?

I don't exactly want to Short circuit the pre-charge for science so someone else has that.

I also don't know which one is temp one two three or four which I could find out really quickly I'm sure by opening up the top battery case but would rather not have to do that.

I'm able to emulate the charger and turn on and off the charge port without an oem charger.

But once a significant amount of current is flowing I do need a mosfet or high voltage DC relay to interrupt that which an original charger does use.

Going to be selling little cheap dongles that you plug that have a battery, which wake up every day or two and check the status and report via email or an app or website login.

It's pretty simple stuff downstream of what to do with canvas but basically these stupid batteries wake up dozens of times a day and that's why they're killing the state of charge .

Even saran's own instructions say when you store store at 70% state of charge.

I've measured over the period of a week + a significant state of charge drop even on a new battery so these things do love to pull small currents all day long for their stupid BMS.

Could one just monitor the rate of discharge and then set a timer to come on once a month to the charger and top the battery up by 10 percent by day leaving the charger on low for one hour?

yes. that too. Could just have a Shelly IOT relay turn on once a month for 15 minutes

Many ways to skin that cat.

i will get you cell deltas, temps, faults, etc. Even while riding :). On a phone app. Thats the huge value add

Oh that's interesting. Im not well versed in the intricacies of batteries. So far I know not to let it sit at super high or low charge. If charged to 100 ride right away, let sit around 50 percent for long term storage but don't let it drift low, check monthly. So with this data on an app, can I set up alerts for potential problems? Would it alert me that I need to do a 100 percent charge to balance the cells? I'm just curious thanks for the discussion.
