Hi Andrew ,
The 12ah is around 1.6kg , and i might use it to power my yaesu ft 891 as that’s capible of 100w but 50w is my licence limit . My 1st activation on Saturday once set up only lasted around 35 minuites , over 10 contacts with 4 s2s and action was pretty fast so soon was off back to the car, 2nd one was around an hour and similar amount of contacts .
I already have 4 18650 3ah cells was thinking to join in pairs to make 3ah upto 6ah and join the pairs in series to get tge required voltage .
Have these holders for 18650 , so would be pretty neat .
