affordable battery tester
I understand percentage better than volts. Is there a battery tester that gives you percentage to help me understand the available charge of my batteries on Fiver.

Everybody knows not to rely on voltage during charging, under load, or too soon after charging or load.
Wrong on two counts.
EVERYBODY doesn't know anything.
And most people experienced and trained in electronics will find voltage measurements under the conditions you mentioned very useful......IF you understand what it SHOULD be in those conditions.
For instance:
I watch the voltage during charging to be sure it IS charging and to see when I can discontinue the charging.
I watch the voltage during discharge to get an idea of when I need to reduce the load to extend the run time......or to know when to start charging.
And I watch the voltage immediately after charging (with minimal load) to see if it drops too fast.....which is an indication of a failing battery.
