This is a BMS charger that would be as universal as possible for testing Li-ion or LifePo4 cells.

This study is an example how to build a 3-phases 230V/380V from a 12-24V DC with an Arduino Uno
We built this to help our farmer friend in Thailand track his truck to prevent rice theft.

Hi, Here are some news. I'm sorry not to be able to answer to all requests. First, I do not understand why but I do not receive any notification when a message is posted. By the way I do not have so much time.
But, there are people this request for information here, and those who read the manual and then can find my private email address....
The V3 software version is ready, with several improvements. LifePo4 24V battery pack is under test since 4 months.
Also V3 and V4 PCB version are ready for testing.
I am very glad to have distributed nearly 30 PCB since the very first V1
Hi PU2CLR, many thanks for your shares. You look like a radio receiver enthusiast ! I'm wondering if you notice which one of all these FM receiver ICs is the best sensitive for far FM transmitter ?
I have tested the RDA5807M as its datasheet indicates a sensibility of 1.2uV, however reception quality is not so good in country.
Hi, the very first time the EEPROM values are set to 255. 131, 51 and 41 are not significant values. It must be something that show that stored values are wrong for the project.
EEPROM of the ATMega329p can only store unsigned 8 bits values, so from 0 to 255.
