While it may be hard to always achieve this, try to shoot for a 10% charge rate if weight, budget, and space allow. For example, if your charger is 30 amp, an ideal battery bank would be 300 amp/hours.

Having enough battery bank to handle a 10% charge rate would be ideal. Expect to pay more than this for more advanced features, greater power, or versatility in the types of batteries you can charge.
#Rv battery charger portable
Portable car battery chargers start at under 20, although most quality chargers are in the 50 to 100 range. In a 10 hour solar day, you could have 300 amps of charging power.

The actual useful power depends on battery type and drain rate or the speed at which you draw power from the batteries.Ī higher drain rate will drain more power than a lower drain rate. The amp hoor rating of most batteries allow a user to estimate how much power a battery contains. Deep cycle marine batteries are rated in amp hours when they are designed for deep discharge. Most RV applications operate at 12 volts so you will most likely only parallel battery connections between them. Once you are able to figure out how you can install, mount and safely operate batteries in your RV it is time to determine battery bank size. Other batteries are loacted on one side of a camper and can create an unbalanced towing situation. Many Travel trailers will have the batteries on the tounge which limits total number and can create an extremely heavey tounge weight. Some batteries will require outside venting: Please see our Battery choices and types for mobile solar arrays article for more information on choosing the right type of batteries for your RV.
