08 HV Battery fixed the cheapest way possible? Let me know.

In August I bought an '08 Level 5 with 167k miles for $4k. Known Red Triangle of Death. (But unknown actual issue). Did not know about PriusChat or Dr. Prius. Just a couple Youtube videos that made fixing it look possible. Long story short, 4 modules seems low, bought and replaced for $70, shipped. Used the metal strips from an old wiper blade to balance (worked perfectly). In the process of researching, I found PriusChat and Dr. Prius (was hoping for a free battery check, but oh well). Since then, I've put nearly 1,000 miles including one over 400 miles and two mountain ranges. 1st leg (145 miles) was 52.2 mpg. 4 passengers and a Sam's Club run brought down the average to about 46 overall. I very steep climb up 3k' brought the battery down to 27.5%, but the downhill was 35 miles of Maxed-Out meter. Only concerns seem to be the higher resistance of the modules, according to Dr. Prius. 22-30mOhms, but varies each drive. And everything turning red when I coast/ brake 1/2 mile downhill to my turn off the highway. $3500 less than retail for a $70 fix? WIN or no?
