I always here people saying that if you charge your batteries faster they will deteriorate faster is this true?
Yes its true. Although you can charge at the c rating it is very hard on the battery. Creates a lot more heat internally. I used to charge them as fast as my charger could charge them. They got puffy after a few charged like that and when discharging them like in my truck I had one melt through the chassis. Only way to put them out is with sand. Since then I never go above the capacity. If it's a 800mah I charge at .8aamp, even though my 5200mah batteries can handle more I never charge them above 2amps. The batteries stay cool and they don't puff up.I always here people saying that if you charge your batteries faster they will deteriorate faster is this true?

I dont get what the point of discharging batteries is.In my early days yes, discharging too far was part of the problem, impatience was the other part. I discharged hard and low and charged as hard as I could in the least amount of time possible. I now set all my controllers to the highest voltage cutoff allowed and as soon as I notice a minimal reduction in performance I land or park the vehicle. I don't charge them until the batteries are cold too. Nowadays I pay attention to the details. I went from not caring to being overprotective on my batteries. Motors, contollers, and radios I can find cheap, my biggest expense are batteries. Being on fixed income makes me cautious but that's just me.
OkI was referring to using the batteries in the plane or car or whatever. When I used nicads it was good to cycle them or train them to be push packs. Lipos don't need discharging unless they are full and you want them at storage levels.

I know but having puffed up a lot of batteries in the early days I prefer to be cautious. I'm disabled so I have more time than money. I was stating what I prefer to do. No one should take what I do as hard truth but what I prefer.
I totally agree, there is very little relationship between cost and quality. There is a relationship between cost and service. If you can get excellent service, it’s worth the cost.I agree on the idea that higher cost doesn't mean higher quality.
I usually stick to a 1C charge personally as I have plenty of time to fly and plenty of time to charge. And if I wreck a battery, it's a long way to the hobby shop.
I discharge my large UAV cells to storage as well if I don't use them up in flight, if I am planning to fly it there is plenty of time to charge them the evening before. Some of them are actually rated for a 15C charge but my charger can't put out that many amps!
My smaller cells for FT foamies I'm a lot more likely to recharge to full voltage if the weather is looking decent, that way I have the option to grab them up and go flying. Also, I'm a lot more likely to fly a puffy or damaged battery in a plane that is worth a dollar and a couple hours than one that has more of my time or money into it. Right now I'm still flying the cell that got a hole poked in it in my Bloody Baron... seems to be doing fine!
FWIW I charge to a max of 4.15V/cell, as you are only losing 5% of the capacity but in my opinion are putting a lot less stress on them, especially if they are going to sit charged for awhile.
I've never heard that before. That's pretty deep if you think about it. That's the whole life-experience. Thank you for that one! Yes. I know. I think too much!if you don't know how to tie a knot, tie a lot
