Simultaneously Draining/Charging AGMs?
I have a small bank of 3 or so 35ah AGM batts, the UPG Chinee Goodees. I have two chargers for them: a Meanwell SP-200-15 (13.4A) fo bulk charging, and a two-stage 4.5 amp charger which boosts at 13....

Do experiment and charge all three at 14.4 volts and watch the amperage as it declines. When it drops to 1 PERCENT of the amp hour total of all three batteries (added together) --- reduce voltage to 13.6 and keep an eye on float amperage. It should never increase beyond that magic 1% calculation or if it does the batteries were not bulk charged long enough or you may have a drone in the three. Test them.
