Looking for a good deep cycle battery charger

I have good luck with RC chargers. They have lots of features for the price. Can charge lithium or AGM or flooded batteries. The best part is having control over the settings. You can do a 16v equalization charge. Bring back dead batteries. Temperature compensate if you happen to be charging in really cold or really warm climate.

I charge my 210ah golf cart batteries with a charger the size of my palm. Off hang guess it might only be a 10a max. Which is plenty to for an equalization charge. Not a good choice to be your daily high amp quick charger.
