My goal is to get this to output the maximum 1 Amp and have as quick of a trickle charge as I can without damaging the battery.
You can't trickle charge lithium batteries — but I suspect you're using the wrong term and don't actually mean trickle charging.
Trickle charging is a charging method where a battery is charged by leaving it on a very small charging current
indefinitely, so that it's always kept at full charge. Of the common rechargeable battery types, only lead-acid, NiCd, and special trickle-charge NiMH can handle this. Lithium, standard NiMH, and LSD NiMH (Eneloop) are all damaged by trickle charging. Trickle charging is basically how car alternators top off car batteries, as well as how lots of old cordless phones, CB radios, flashlights, etc. through the mid 90s charged their NiCd batteries.
I suspect instead that you are actually referring to the termination charge, the constant-voltage phase of CC/CV charging where the charging current tapers down to the termination (cutoff) current. Note that changing the termination current setting doesn't change the
rate at which the CV phase charges at (as that's determined by the voltage and the internal resistance of the battery, which changes as it gets full), it's just setting when to stop. Too high a value and you're not filling the battery to capacity, but extend its life, too low a value and you're overcharging the battery, diminishing its life. Just go with what the battery manufacturer says to use.
