thinking out loud:
For me to charge my E-15's six T-105s, it's about 18A (average) at 38vdc
8 hours. That's (18A)(38v)(8hrs) = 5.5 kWh, or about 6 kWh. Assume my
charger pisses away 15% to heat and that buzzing noise... so I'd be
"charged" (haw haw) for drawing about 7 kWh. Where we are, it's about $.11
per kWh. A whopping 77 cents or so to charge the tractor then, sez I.
Even if I'm off by a factor of two, it's still less than $2. I love that.
