ok update time...the vest is done and works great on 3s. outside temp was 96f and body temp was 98.7f after 1 hour body temp was stable at 97.4. water was 48 going in and 65 exiting the vest. 1 8x3x6 inch block of ice lasted over an hour with constant flow. the pump used 928 mah in 1.25 hours on a 3s 5000 45-90c nano tech.

ok now I need help to build a 3 position cycling switch that will turn on the pump for 5 minutes then off for 3 min and repeat with a stay on option as well.

so the switch will be

stay on
cycle
off

any help would be great as I have no clue how to build a cycling switch. I looked into thermistors but could not find an ajustible 12v system that works in the temp range I need that was affordable.
