LiPo C-Ratings and What They Mean

What do assign rates mean, and is there a conspicuous opening disproportion between high and low rated packs?

Charge rates are only what they sound like. It is a amp rate during that we are able of charging a specific battery pack. Most ordinarily we will see this during 1C, 2C, and all a approach adult to 5C. Well what is “C” in this scenario? It is a amp hour of a battery packs. While many are informed with a milliamps, a amp hour is that series divided by 1000. So for a 5000mAh battery, 1C would be 1(5) or a 5 amp rate, 2C would be 2(5) or a 10 amp rate, and 5C would be a 25 amp rate. A 1C assign or liberate should be an hour prolonged process. 2C cuts that time to about 30 minutes. Balancing can extend a altogether time yet this gives we a ballpark in terms of a time it will take during any of these rates.
Your assign rate used to make a large disproportion in altogether opening in a days of NiMH and NiCad cells. The faster we charged a some-more punch we would get. This also tended to lead to reduction cycle life. With LiPos a disproportion unequivocally isn’t that obvious. It’s not a night and day opening disproportion charging during a faster rate. Opposed to charging packs during faster rate we would see some-more advantage from charging your packs only before use since we would maximize capacity. The categorical reason to assign during a rate that’s aloft than 1C during this indicate is to revoke assign time: 1C = 1 hour, 2C = 30 minutes, and 5C =12 minutes. Balancing tends to be an equalizer here, though. At a 5C assign rate, it is some-more expected for cells to get out of balance. The over they are out of change a longer it takes to change during a finish of a assign cycle. This can, in turn, boost altogether assign times.
Higher class batteries can hoop these rates during small to no plunge yet reduce class cells have a most aloft luck of disaster during aloft assign rates. Make certain to assign your battery according to manufacturer recommendations to safeguard prolonged life and good performance.
