The Jaro Fan recipient texted me that he's been killing his Single engine battery, as he can't live without the fans in his
yota minivan.
It has been pretty hot and humid, for this area.
I forget what they can draw turned up high, but I wired them with a ciggy plug originally, and he has to turn the key to accessory overnight to use them, and there is likely considerable amount of additional parasitic draw on battery with the key turned to accessory overnight.
Talked options, which is difficult as he is not in the drawer with the sharp chisels.
I said lets replace your group 24 engine battery with a new marine battery, I'll run new fused wire from that to the back, so he does not have to keep key turned to accessory to power fans all night. Keep old battery placed in back, charge it when engine runs via an Anderson Powerpole disconnect on engine shutdown.
Shows up with a newflooded group 27 marine costco interstate battery, too big to fit in engine compartment.
Fits between seats nicely. Sent him off for 10-2 landscape cable. Gonna drill hole through firewall. Anderson powerpoles fused at each battery. Manana, or the day after that.
No chance of ever fully charging it, but at least it will charge every time he drives, and remembers to plug andersons together. Battery might last longer than him, with his poor health.
I hooked him up with some of my andersoned/12v receptacled cords/ battery post clamps for the time being, so he can crank the fans up as needed until manana becomes yesterday.

I got some Delta 7K rpm 50mm x 20mm computer/axial fans.
Only needed one, ordered two, three arrived.
One is going on my powermax 100 amp adjustable voltage power supply/charger. This device came with one 80mm pusher fan thermostatically controlled. I was running it with a manually switched 60mm puller on the opposite side, but now that 60mm aperture is 80mm and next to that original 80mm a 60mm fan was too big, but 50mm was perfect.
My salvaged 50mm fan was too weak, so Delta!
I have 2 80mmx36mm Nidec fans from Surplus center. 109 cfm. Very powerful. 4$:
Deal alert!

One Nidec is on my MV-50 12v air compressor. It no longer gets too hot. None of that 20 minutes on 30 minutes off duty cycle crap most air 12v air compressors say.
The other 80mm Nidec( still unemployed) has been hardened for underhood duty, its split flow feeding the backs of my alternators cool air from in front of radiator via flexible aluminum 'pre heater hose' instead of the alternators sucking hot underhood engine/radiator heat.
Overkill for powermax duty.
So I ordered two more and each alternator will gets its own Nidec.
Because i am the ventilation lunatic.
