I would not recommend Baofeng I had one.
The problem is really the batteries in your case.
But there are some very good FRS/GMRS radios out there. The Baofeng is kind of strange as the one I had (UV5R) was not limited to frequency. Oh the software would say "out of band" if I put in say a GMRS Frequency (OR FRS) but the radio had no issues if I did it from the front panel.
And selling radios that can do both Ham and GMRS.. can be an issue.
I would recommend the radios you have with rechargable batteries (At lest 2 sets per radio) and enough charger to charge them. also go to someplace like Batteries Plus and get the highest capacity batteires that will fit.
Option 2 is go to arrl.org then get the technician license study Guide. then you have a long list of ham Radio handhelds that can easily run 8 hours at medium or low power off a single charge. the batteries also charge in place
Yesau, Icom. and more are all good. starting price for the better ones is around 100 used up to about 500 NEW...
Now a bit about those 500 dollar jobs (or is it 600) The one I have was 400.
The more expensive ones are capable of both Digital and Analog operation.
So Here I was last week, in hospital, private room. but did I have people to talk to.. Well yes. you see I had my ICOM ID-51A+2 in Terminal mode (Radios off and on a cardiac ward you want all radios OFF. wi-fi is ok as is a modern cell phone but NO RADIOS) and when I woke up Wed Am I was chatting with a fellow ham in Australia (From Port Huron, Michigan USA).
Summer 2019 I "Worked" a race. 7am to 2pm on a single charge and still had charge left.. Full power analog mode (5 watts) did not talk much though.
I had back up batteries (AAA's) just in cuss. have yet to use 'em
