Re: Ample Power vs Balmar vs Xantrex
Add Electro-Max to your list of replacements; the ability to kick out 90% of rated output at idle makes it a winner in my book.
Your 4 t105's are 450 AH's, 25% of that for bulk charging would be 115 ah, with a echo for the rest. The Electro-Max 100 would do, and is possible without having to go with v-belt and expensive pulley mod's.
That's what I'm looking at for my set up.
Lessons learned are opportunities earned.
