I would not even use a 3S Lipo (I see the DC/DC charger push 14.7v ... this will fry a 3S Lipo relative quickly)
As I mentioned above it was essential that a
5A fuse was used and contact immediately lifted when charge commenced, but yes this is definitely not a recommended procedure and was in my case for testing purposes only.
Actually, nothing mentioned in this thread would be recommended, period
Ok ... if it was for a short time ... yes it is relative safe ...5A charge in a Lipo ... I bet you would need to use a relative high capacity battery at around 50% SOC ...anyhow ... details ...
About that nothing mention here is recommended ... this is questionable.
I think there is evidence that the BMU is pessimistic about battery SOH
I'm still not convinced that DBCAM is the perfect solution (maybe if the charging process is at 6A or even less .. maybe) .. since anyhow the BMU firmware is "strange"
So ... reset the BMU is looking a "decent" option for increase EV usability ... but ... it needs to be done in "aware way"
The original Lindqvist Method, or the short version ... don't have any risk at all ... it is just about disconnecting the 12v battery
Clearly, the BMU reset via MUT is even better .. but this require download "pirate" software from the net, questionable drivers .. etc etc ... so quite some time for prepare a PC and few dollars for hardware and driver license ... in my case I did find easier to use the Lindqvist Method ... if I would have fail .. possibly I would have consider the MUT approach ...
Else ... it is also possible to ask "nicely" to a Mitsubishi authorized service to make a BMU reset .... I'm sure some would be open to the customer requests
