RSSI of -48 dBi? Seems a mistake to me when RSSI is in dB-isotrope. It highly unlikely that you reference RSSI to an isotrope. “dBm” is more apropertiate IMHO

first use of new gluegun… aaaaargh 
dual voltage power unit with 4 x 12000 mA in 2S2P balanced config, output 8.4 v (dc/dc to 5 and 12v)
before mounting the cells I charge them individually to an equal value, mount the balance board and leave them balancing for a night, then discharge the pack and recharge… and finally test.
goal is 2 days working on battery’s (without sun/charging)
test GPS module
ruggedising the enclosure for outdoor use

So a man contacts me via TTN, asks can we meet and talk LoRaWAN, drops the letters “PIR” in casual concersation and I go all @BoRRoZ!
…and build a PIR node to demo. My ultra low power PIR’s vanished in shipping but this should go for a while on a 18650 for demo

Which ultra low power PIR’s did you order?
you can modify the 'standard PIR’s to operate @3V (and lowering the operating current)
or buy a low current one like this module (15uA!)
but don’t forget… low power comes with a price… detection distance
