Yes, but be careful that if the voltage of the battery is higher than the power supply, the power will flow from the battery side to switching power supply and damage it. We suggest adding a blocking diode in series of the positive output to protect the RP1050-XXSV. Also, be careful about the heat problem of this blocking diode. Moreover because charges time can make way closes the power source overload work and if model is using non fan then addition fan cooled need to be installed. If it's fan cooled model then allow us to revise reduce the over-load protection spot to guarantee the product security.
