Yes i'm aware of that option, but i took it more as a learning experience and was not ready to sacrifice a working battery for this purpose and as was mentioned in this topic, newer batteries have much better BMS and the lock-out is less common.
I was also interested in looking into what was possible to do with the 1-wire communication between the battery and charger and reverse engineering the firmware would make that possible but i don't have enough experience and time with disassembly to work that out.
I read the firmware a few years ago
Which programmer did you use for this job ?..
I used a simple USB-UART bridge and used the ROM serial bootloader. For the software i used Renesas own program and my own python script.
