There is serios mistake diodes can be connected btw adj and out catod attached to out, and in and Out catod connected to in !In case You connect matlab rechargeble battery first before mains, or mains suddenly stop, IC might be damaged from reverse voltage !with out diodes it can be unhealthy if matlab programming input of matlab programming IC shorted to ground which is extremely unlikely. so matlab programming above configuration is satisfactorily safe. Hi sir Swagatam, can u please help me, i are looking to build matlab simple lead acid battery that can charge matlab 4Ah to 200Ah battery.
