I spoke with a salesman from Lithionics today. He claims that a 200amp lithium battery will equal 2 8Ds with 500 total amps. He also iterated that their is no voltage drop throughout the capacity of lithiums as lead acids have. So you would see a constant 12.8 volts or so regardless of how many amps you are drawing unlike lead acids where the voltage will drop considerably.
His batteries also have a builtin low voltage protection that shuts off the battery to protect it when it gets to the preset voltage. Don't remember but it is around 10% of amps left. So he recommended a 200amp lithium at $2400 (and it can be air shipped) to replace my 8Ds. Or you could get a 400amp for $4500 and get twice the amp capacity! And his batteries are drop-in ready.
Sounds very interesting. So who's gonna be the first to try them?
