I must admit, I'm an electronics noob. I work in software, and I'm starting to realize that the world of electronics is more complicated than I had anticipated.
In a previous project, my brother built an electric truck using 24 deep-cycle lead-acid batteries. The batteries were similar to this battery, which has the following specs:
- 6V high capacity Deep Cycle power
- 230AH at 20 hour rate
- Weight of 24 batteries: 696kg
As some of you may have heard, Tesla just announced the Powerwall 2, which has the following specs:
- Cost per kWh: $393
- Comes with an inverter (I have no idea what this is or if it's necessary)
- Weight: 110kg
The electric motor for this car conversion has a controller that maxes out at 3000 amps. Normal cruising amps is around 1000.
Including a Powerwall unit might not be practical for use in an automobile, but I'd like to get a better apples-to-apples comparison of one over the other, as it's possible that a similar type of battery might become available for use in cars.
Obviously the Powerwall unit weighs a lot less, but does it provide the same amount of power? And how does it compare in terms of energy storage capacity?
