I am using a Optima Yellow Top D51 (38 amp hours). This works great for my Trillium
4500. The loads are: eight 1156 LED bulbs (each bulb draws .12 amps at 12 VDC), and one LP gas detector (draws .075 amps at 12 VDC).
The battery discharges down to 50% in four or five days based on average 5 of the 1156 LED bulbs being used 5 hours per day, and the LP gas detector being using 24 hours per day.
Beyond four or five days (haven't had to do this), I can partially re-charge the battery using my smart charger powered by a pure sine wave inverter in my tow vehicle. Other charging options would be a solar panel
or a generator
Keep in mind that a battery is ONLY needed if you plan to camp without shore power.
