"balancers are just a money grab"

[Bondonutz]

Here's one to make you think ?
One of my buddys whom I rarely see for RCing due to his schedual asked me to take a look at his packs. He has a TP 3s 3850mah and a Venom 3s 4000mah. These packs are over 2 years old and never seen a balancer, he uses a Multiplex charger only.
All the cells in both packs had 4.18volts when checked with voltmeter. That blew me away ? These packs are run hard in a Slash once every few months and the packs are stored at full charge for months at a time.
Is that dumb luck or he's super lucky with his packs qaulity ?????
