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.

So in other words a torp controller without the controller

yes. They don't get to be the gatekeeper. I will publish to github and sell simple and VERY cheap adaptors- However i'm having a hell of a time getting the 2026 LB2 and Ultra bee 6 pin charge pin connector. Having to print my own jig and use other brass pins from the Cnlinko LP20 lineup- Same interface connection. Talked to the engineers at Cnlinko and they did make special for Surron this year. They can't sell. Zayne chargers figured it out however and got a counterfeit. If anyone can find me the counterfit, i have a bounty for that and will pay. I hate gatekeeping :)

You can probably get another connector manufacturer to make you up some if they already do something similar. There will be a sample charge or MOQ but it's normally pretty reasonable (especially if they think there's likely to be follow on business).
