Charging lithium iron phosphate batteries. Lithium battery expert. I have 7.5 watt solar panels charging life4 batteries. Each battery has a pcb circuit. The 12 volt panel actually produces 18 volts max. How ever i have a 1000mf cap on the input then a 12volt regulator then(on the output) another 1000mf cap then 2 standard diodes which drops the charge voltage down to just about 11volts constant. The current input is at max 550 ma. Any suggestion to improve on this circuit? The pcb works great on the drop and for any over charge issues.
