You don’t need two power supplies. Just pick the power supply that has enough current to both power the radios and supply a healthy recharge current right after a power outage to the radios.

Hello all, We're looking to build our first DC power site for small MicroPops and I see two options after reviewing the WISPA archives. The first option would be the the SDR-240-24 and DR-UPS40 with Two 12v batteries powering a Netonix DC switch. The second option we were looking at is just doing the AD-155A with one 12v battery but I see the charging current is only 0.5 amps and voltage is only 13.3V which is not an optimal float voltage. My question is, to keep cost down, would we be OK going the AD-155A route with the slightly lower float voltage with a 35ah battery? We're ok with the battery taking longer to charge but I'm just most worried if the 13.3V will wreck the battery or not. Thanks all -- Darin Steffl Minnesota WiFi www.mnwifi.com 507-634-WiFi Like us on Facebook
