what's your definition of "good"?
what exactly and specifically do you want it to display? wh? ah? battery gauge with bars of power remaining?
without any of those details, my recommendation is the https://www.ebikes.ca/product-info/cycle-analyst.html, because it has all of them. if you don't need any of it's control features, you can use the v2.x, though i don't think that one has the battery gauge, just the wh and ah.
the 3.x has a lot of additional features including temperature monitoring and ability to modify throttle based on lots of different things, and to use pas to control your system if you like. https://www.ebikes.ca/product-info/cycle-analyst-3.html
if you don't want the ca, then you can use any of hundreds (thousands?) of different el-cheapo wattmeters that do either wh, ah, or battery bars, or some combination thereof.

tk15 coulombmeter is pretty good all around. I use them on all my lifepo4/li-ion packs. The 50 amp model cost less then 25 dollars (you can find on ebay also amazon sells them) and can read up to 100 volts, that should be enough for a 20s. I like this meter because it shows everything on the screen, you don't have to cycle back and forth. The buttons on the front is just to program the full/low voltage and the battery pack amp hour capacity.
