The RF Workbench / Solar SLA charging and maintenance for unattended transmitters
« on: November 06, 2018, 1131 UTC »
Hey I'm planing on setting up some beacons sometime soon and I would like to pick everyone's brains in regards to solar charging some sealed lead acid batteries,  I'm looking at using a 7.2 AH 12V SLA, I haven't decided on solar wattage yet, I'm thinking I'll need about 12 to 16 watts of solar to charge, what have your experience's been with solar charging? what's the simplest charging circuit without sacrificing too much battery longetivity? I know its a compromise.
