35 amp WFCO is a good converter. Normally you will see 13.6 volts soon after plugging in and it will drop to 13.2 volts after several days of minimal use. If the battery is super low (less than 50%) you should see voltage steadily climb to 14.4 volts and hold during the first four hours. After which it will drop to 13.6 and eventually 13.2 volts.
No other battery charger is needed or recommended (by me).
Lights are a battery hog so go easy or bring a battery lantern if you want to stay up late.
Return the charger and consider putting that money toward a second battery in parallel.
