What c rate do you all charge your lipos at?

So I have my fancy(to me at least lol)new charging setup and finally have a chance to runs a truck or two.

What charge rate do you all do? I’ve always done 2c rates and have had no issues.

Charged an SMC 6s 5800mah on 2c in just under 12 minutes. Wow that’s quick!

Always at 1C, I've heard faster rates wear on the battery and create risk. It's a calculated tradeoff for me, and an extra 30 minutes of waiting wins every time against shortening the life of my $100 battery or lighting my workshop on fire.
 
I agree with both of you, and I usually do 1c charge rate. 2c seems to be doing fine for my lipos lately, so that’s what I’ve been sticking with.

But I also wanna put this fancy new dc charger through its paces! 😂🤦🏻‍♂️

Wonder how fast it’ll do 2 6s lipos 🤔
 
Completely empty empty to full is 30-35 min at 2c. You got enough juice with the setup to charge 5 of thoes lipos from dead to full in that same ~30 min!
What's that 110f measurment?
I charge 1c, or less if I have the time, but usually I don't. Kids want play now, now! Not in 60 min! So I charge at 1.5-2c when bulk charging usually. I'm also ok with most of my lipos being abused a little bit.
You got yourself a hell of a nice charger, that 2amp balance charge is a super nice feature that's often overlooked and will be very much appreciated on lipos that don't balance well. Happy to see its all working after the psu woes!

The 110F measurement is the charger temp, you can set the fans to come on after a certain internal temp has been reached.
 
Hi there,
I'm no expert so, when everyone says "I charge at 1C", I just don't get whet it means...

Let's try something... does it mean that:
If my battery is a 3s, 11,1V, 6000mAh, and officially 80C (but a calculation found online told me, through the resistance of my battery given by my charger for the highest resistance (3mOhm) my actual C thing was closer to 20C).
Is this "20C" to be considered?
Or should I set my charger at "6A"?

The "actual C rating" tool I used is here: https://www.radiocontrolinfo.com/information/rc-calculators/calculate-the-real-lipo-c-rating/
 
The high C rating on a battery is an indication of how many Amps can be dumped by the battery.
An amp hungry system will like high ratings.
The rates are exaggerated, though.

In a similar fashion the charge rate is stated. Usually 1C or 2C
In your case 6 amps for the 6000mah battery for 1C
 
Anywhere from 1-5C. Depends on the battery.

I would NOT charge some cheap low quality battery higher than 1C.
 
1C and have more than 1 battery. 2 batteries is enough for a relaxing day out with a decent amount of bench chatting between runs. 3 packs and you can chat less, bash more.
 
1C if I have the time, 2C if I don't, and 3-5C if I'm meeting people and forgot to charge something. I can't find it, but I remember a post several years ago where someone took several of the clearance 2200mah 3s batteries and ran them though 300+ charge discharge cycles in groups at 1C, 2C and I think 5C. It basically showed no difference between them.

Can't find the one I was thinking of, but did stumble across a post where a guy was pushing 1300mah Turnigy Graphene batteries at 10C and 15C charge rate.

I too use old server supplies with a floating ground on the second to get 24V. Amazing the amps those things can put out.
 
You can charge most batteries at 2c just fine. But watch out for some smaller batteries. I have seen some say they don't even handle 1c.

The extra wear on the battery charging at 2c will be fairly negligible for most packs. But technically, the higher the C charge rate, the shorter your battery's lifespan will be. Racers tend to charge at much higher amperages for their batteries to get their IR values as low as possible. Like 30-40A or more.

I rarely go over 1C. I always have a planned run time, so I just make sure I have my battery(s) charged before then.
