I am using for my setup 4 x 7 Amp new AGM batt, converted to Alum, a dc-dc converter and a REMF charger (for the fourth battery). The result are so far promising, but I have to run more charging cycles, to settle the alum batteries. I managed to charge 3-rd batt to 13,3 volt (alum), and 4-th batt to 12,8 volt, batt 1 voltage is 11,87, and batt 2 is 11,4 volt. The Bonus was a free light - 2 watt LED, running from REMF coil (ferrite stick all lenght wounded with 0,2 mm wire, with the LED on top
).I am planning to discharge alum batts to 10 volts limit - so what do you think, is this limit ok, or I should keep discharging only to 11 volt?
On the other hand, I am planning to get a little bigger batteries, as my budget aloud, but the question is: should I get 3 normal car batteries (60-70 Ah) and then convert them to alum, or, option 2, stay with deep cycle 35 AH?
Option 1 - 70 AH
Option 2 - 35 AH
Please use google translate, those pages are in romanian.
Edit: HERE is translation of option 1
and HERE is translation of option 2
Unfortunately, this is what I can choose, right now, so I have to choose something...
One last question: what about THIS inverter?
Best regards,
Teodor
