I use LTC4020 with your evaluation board DC2134a .(for charging 2x12V 20Ah lead acid batteries)
there is a big problem :
in stage 1 and 2 of charging cycle (Constant current charging and also absorption phase), if we disconnect the battery and reconnect it again , it is IMPOSSIBLE to system come back to continue charging . the output voltage of the board will be about 25.5 (the voltage of batteries) and the charging current will be about 0.4 .
Just we must disconnect the board's input voltage and reconnect again , to system goes to continue charging batteries normally with correct current and voltage . (for example 6.3A and voltage goes up to 28.8)
can u help me ? it is so important for a battery charger system to recover after disconnect and reconnecting the batteries .
