Chaaaaaaarging!
#1
Back yet again! Have done a bit of light research on the topic, but was just curious what you all run. I have an iMax B6, and charge either one 4S @ 0.8A, or five 4S on a parallel board @ 1.8A. I am getting a new ISDT Q6 in, and am curious what amperage you all push on your batteries? I always want to keep it safe, and never harm the batteries, so I have always tried to keep it low. Thoughts?  Big Grin

I normally charge batteries at 1C, but if I'm in a hurry, I'll charge them at 2C.

I use an ISDT Q6+ with a 350W psu and if I were to charge a single 4S 1300 mAh I would use 1.3 amps, when I use a parallel board for the same capacity of batteries I use 1.3 amps per battery. 2C should be fine but I find I am usually not in a rush and like to baby my batteries. Also I always use 1C for my goggle batteries.

Ever run into any issues with that?

Nice! How do you like that charger btw?

I'm very happy with it! I am planning on getting a voltage reference to calibrate it however. They are not perfect from the factory, though pretty close I hear.

I just think it's worth the time to make it as good as possible to max the battery life. Joshua Bardwell did two good videos recently on calibrating these chargers.

I have a few ISDT, great charger. I have a few PSU from old computers I savaged. I usually charge at 1C in parallel.

Nah. Check the specs for your batteries. Some are quite happy to be charged at 5C. It all depends on the battery.

Imax b6
A wee bit inexperienced here but b6 doesn't let you charge at the wrong rate..also bought life battery for taranis q x7 and the Imax b6 supports its charging mode

Imax b6 allows amp control. It charges at any rate you want up to 50W max.

iSDT SC200 here Smile
I only parallel charge 2 packs at once, @ 2C, e.g. for 4S 1500mah packs i use 6A current.
I can charge more packs at once, but I found it easier to match the voltages in pairs, and easier to handle if there is a problem.

I always return my packs to storage charge after a day's flying.

That way i can be sure that they are all close enough so that I can charge six at a time in the morning on 1C. Having six batteries ready to go after 45 minutes is a great time saver.

I usually storage charge mismatch lipos and then parallel charge. I find that I am more consistent when I land that the lipos are in the general voltage.

Probably some of the best tips I have encountered yet!! I have always wondered about doing that, but hesitated to do so. Now that I am looking at the ISDT, I wonder, for the extra price of this setup, is it really worth it. I still need to get a decent power supply to run the thing, which is pretty big and loud. 

On a side note, have any of you tried the "current sensor calibration" through betaflight? I was thinking of giving it a shot here soon and was just curious.
