The chip only works with Homage, Inverex and Mercury UPS, I have installed 100’s of chips they r working perfect , Ok dude let me elaborate how it works, the chip is basically a (microprocessor + Rom + Ram + i/o) small microcontroller, the Mathematical state space Model equations of perfect Battery r stored in its ROM, the Algorithm is activated only if the FAST charger is in progress it keeps on monitoring the amount of Charging current flowing into the Battery & compares the Reading with the Perfect Battery Equations if it diagnoses the current Battery is faulty then it kicks in the Dedicated charging Algorithm based on first order sliding mode controller & cheats the Factory fitted processor & manages the amount of Charging current + duration, I designed it myself by doing a reverse engineering of a factory fitted Motorola (mc68hc901) CPU chip,
