I have read the other thread with 11pages but still don't get it. Can I just swap LTC chip? Analog.com have pinout of the chip. Is it possible to check voltages on its pins from cells? That way I could check if there's a fault between voltage tap and LTC chip. If LTC chip swap fails then I should get replacement CMU(any will do?) And swap eeprom from my faulty CMU. But then which chip is eeprom?
