I'm replacing (3) blue tops with (3) Deka 8A24M AGM's. 1 for start/crank and 2 for stereo/house bank. I'm replacing my battery charger as well. I've done quite a bit of reading, and believe I have it narrowed down to two models, but am looking for some advice on choosing between the two to make sure I'm correctly supporting the investment.
I've narrowed it down to the Dual Pro Professional PS2 (2x15A) and the ProSport 20 Gen2 (2x10A). From everything I've read I want to be somewhere between 10-15% of total bank amp hours per leg. The Deka's are 79Ah each, so call it 158 on the house bank. The Dual Pro is shy of the 10% mark by .8%. While the Pro Sport is even farther off the mark, their "Distributed On-Demand" technology claims to distribute the total 20A to the bank that needs it. I take that to mean that if my start batt is fully charged, my house bank is going to be getting what it needs to properly maintain it.
I don't use a switch, but I do use the SurePower 1314 inbetween banks to seperate them.
My modest setup nets out around 1500W RMS, but I will be replacing my Pro80's with Rev10's this spring and with the amp re-wire I'll be somewhere around 1750W (Syn4 and Syn6).
Really appreicate any advice you guys can lend me. Thanks!
