Looks good, but I don't know which mode to use, mode 2 or mode 3, mode 3 is for cold circumstances and for several AGM batteries with more then 14Ah, but Mode 3 does mention trickle charging once full, while mode 2 (for car batteries exceeding 14ah) only says after charging the battery, there is float current is available for the battery.
(mode 1 is for motorbikes)
Which one to use?
