I have got 2 maintenance free lead acid batteries. 12V 40AH each.. they are connected in series to UPS. problem is, the UPS's charger doesn't charge the batteries quickly enough..
can someone give me schematic to a 24V @ 6~10A smart charger circuit for the batteries (one with full brute charge and then float charge, so that when the battery is fully charged only a trickle current is applied )..
i have searched it on google, but no helpful results.. can someone help me here?
