So, I did the math and it’s just no cheaper to buy 30-40Ah-50% depleted Nissan leaf modules for $60/ea. when I’d need 7 to get 48V and 7 sets (49) to get close to 250Ah…the only excessively expensive thing with Tesla is BMS…but I think you recoup that by the very slow capacity loss.Not sure what you mean by "12V shunt"?
If you can afford them, Tesla is fine. @Functional Artist uses Chevy Volt modules.
Yes, by all means, do a build thread if you're up to it. Helps anyone else that might do a similar conversion and you can think out loud before spending the money or doing something.
Sorry, I was trying to communicate a 48V step down converter for 12V accessories…as the current one in my setup has been Jerry-rigged to the point of unusability.
As far as mechanical system design, the nice thing about EV is that, if it’s not being used, it’s not creating heat, so different from ICE that actually need more fans when it’s not moving. Most of my use with this vehicle will be drive 100 ft, stop unload, drive back 100 Ft reload, which is one reason I chose EV, all that time idling is wasteful and hard on vehicle and nature, or you can replace a starter every couple years.
