Is there a way to reset these LLT smart bms’?
Had an idiot moment this morning. Playing around with the app this half asleep and f’d with the cell number parameter. Long story short it didn’t seem to appreciate it and now won’t let me connect to it to fix it.
Just keeps asking for the password over and over.
I’m not sure if there is a factory reset on those, but the password is usually 123456
Why did you feel the need to tinker with the settings?
It hasn’t been charging past 49.6v since I blew up that last vesc. I’ve heard about a few guys having trouble with these LLT’s doing the same thing.
I figured it could also have been the battery sitting at 4ish volts while the board was of the road too.
Ive got it all disconnected at the moment hoping maybe it’ll possibly reset?
And yeah keep punching in that password but it just keeps asking for it
It’s been a minute since I used the app, but if I recall, reinstalling the app should revert everything back to defaults.
Tried that too
That doesn’t make any sense for settings that have been saved to the bms
My best guess it to change your title to ask if anyone can post their settings so you can make the changes.
What are the cell voltages in comparison to each other?
Nah my issue is that I can’t connect to it at all now
They’re all perfectly balanced, only get to 4.15v though. Overvoltage, full voltage etc was all still at the defaults.
I follow you lol. I had to think about that one a few seconds lol.
I still stand by my best guess though. There are multiple people that use them and some of them are probably still running stock settings.
Stupid question. Have you tried removing the blt module for a while and trying again?
Wondering if the blt resets after time as it’s gets it’s power from the bms. And without power of any kind, it shouldnt be able to save anything…?
Yeah I’ve got it all disconnected at the moment. Thinking I might just replace it with a dumb Daly or something anyway as I still have the issue of not charging to full voltage.
So you’ve tried 12345. Try 00000?
I do recall having an issue once where it would constantly ask for the password. I can’t recall specifics, but I eventually got in through putting in the password and anything I could think of that I might changed it to. Just my experience
Rather than trying to find a new bms, i’d be much more inclined to find out why you’re not reaching full voltage.
Does the charger put out the full voltage?
Is your multimeter accurate?
Where are you taking this full voltage measurement from?
Do the cells reach full voltage on the charger and then settle to the lower value?
How many cycles do you approximate that the battery has seen?
Replacing the bms isn’t likely to achieve a great deal if there are underlying issues.
The xiaoxiang app can be temperamental at the best of times, there can be a lot of fumbling and repetition involved.
Yeah both chargers are sweet and charge my other board to full voltage. This pack is only 6 or so months old.
Checked the leads right at the battery with multimeter and reads the same as what BMS and vesc were reporting. Guessing it probably did the damage when it sat for those 3 weeks or so at highish charge
Got in briefly to the app. Seems to have bricked itself on overvoltage protection and won’t populate or let me fix any of the parameters.
It should be 123456
+1
What app version on which platform
Only lets me open the latest version from the LLT page. Android platform.
Bah I’m done with them. Can’t see either of my packs now.
