GNB BATTERIES

CHARLIEP
This old man can't figure this out .[ gnb sprinter s12v285 f ]-12v- 285 watts per cell 15 min rate to 1.67pvc nominal float voltage 13.5 to 13.8- 25degrees c-,  77 f  how many for 1500lb 3 wheeler?I have 17.how far & at 60mph

It really depends on the aerodynamics of your vehicle.

285W/cell * 6cells/batt * 17batts * 15minutes / (60min/hr) = 14.5kWh
at 15-minute rate

Those batteries weigh 53 pounds each; 17 of them is 901 pounds.

If you put all 17 in a light-weight, aerodynamic 3-wheeler that got
250Wh/mile, you should get about 60 miles range absolute maximum.

That means you'd have about 30 miles usable range for long battery life.

Your vehicle would have to be very aerodynamic to get 250Wh/mile at
60mph. On the other hand, I'm using the energy numbers for a 15 minute
discharge; a slower discharge should get more usable energy.
