2C high voltage charging anyone?

[F-150 727]

 I usually like to charge my batteries at 3/4 or less than the stated charging rate of 1C. I have a battery that says 2C charging capable, but I don't think I want to do that. I'm not one who has to get them charged instantly I'm fine with sitting in a chair, taking a nap waiting for batteries to charge. I just feel I'm killing battery life charging at full rate or twice the rate. 

Anyone notice battery life shortage while charging at 2C?

I may try and do some 2C charging and see what happens....I'm always experimenting.

I have a Zippy 4000mah rated at 3C charge rate.

That is 12A but I do not have a charger that is 12A able, but had charged it at 6A (1.5C) and had not noticed any problems.

The thing is, do you believe the manufacturer's specs which states the C that the battery can take, or internet "experts" that say you must charge at no more than 1C?

I usually charge at 1C and find that's not a problem.  Most of my LiPos are pretty old now, they can take a while to balance (in fact I often stop charge once they're mostly there as it can time out trying to get the final balance right) but they'll still last a couple of race heats or plenty of time bashing in the garden.  And I'm getting over 4 miles out of my 3S walking batteries despite a very heavy rig and over 2A of torches on the roof.

On rare occasions I charge at 2C - mostly when I decide last minute to go walking and I have limited time to get to the hills before I run out of daylight.

Most of my lipos are four or five years old, and I never charge at less than 2C. If it shortens life, it can’t be by much.

I sure some lipos are now advised at being able to charge a 5C!! 🫣

Most of my race liHv batteries say upto 3C, but I charge at 1C, and only go higher if I'm running late for a final.
