The 3 X 18650 Battery pack I've installed in my V5 give me height hours running time at 10% transmitting time (on dummy load), I installed the same battery protection board as yours and I plan to modify the charging circuit. the mods are :
2 separates 12V rails, 2 X 5V rail (one for TX, one for RX)
Nextion 2.8" touch screen feeded by the Raduino
VK3YE's AGC (12V RX)
XPT8871 AF amp with tone control (5V RX rail)
SSM2167 mike compressor (5V TX rail)
with these adds the power consumption is not very different (not verified).
I plan to re-install a second arduino (standalone analyser) with it's own 5V rail.
I will check the real consumption datas and write a complete report.
Bonne journée !
