Is charging at 2c becoming common practice or is it just specific to certain types or brands (kong power, air thunder) of batteries? I seems that many people are charging at this rate and I myself am still charging at 1c. Any help would be appreciated!!

hi
for a 1000mah battery 2C would be 2.0 amps , i believe certain new batteries can handle this , i am sure that not all lipos can charge at the higher rate , i would only trust printed info directly from the manufacturer , and then only charge in a safe environment , and do not leave a charging battery unattended , better safe than sorry , HTH , dana

Most batteries rated 20 or 25C discharge can be charged at 2C. It always reduces cycle life, so only do it when at the field. Charge at 1C at home.

And, ONLY charge at 2C on an "intelligent" charge rig. This is a combination of charger/balancer that can TERMINATE a charge if balance goes bad during the charge.

Thunder Power TP1010 charger and TP210 balancer can do this when interconnected via a data cable (that comes with the charger). V-Balancers can do this when in "charge through" mode. I'm sure there are others.

DO NOT 2C CHARGE without a 'cutoff' capable rig. Otherwise, you are risking a fire or worse. I've got about 50 or 75 2C style cycles on some big TP 6S packs... and out of all of those, the charger has seen fit to terminate the charge 2 times, total. No reason I could ever detect, and after a 1C charge and so forth, everything was fine. Those 2 times would have been history for a $300 pack and all surrounding flammables...!

So, do it, just do it with the right charger/balancer setup.

It all depends on your battery manufacturer. All the major quality brands already support 2C charging. But for those unknown inexpensive brand, better be careful and charge at 1C only unless specifically confirmed by the manufacturer.

This is what commonsense said "As far as charging rates. Lower rates wont hurt, but the benefit might not be as substantial as you might think. We have successfully charged our lipos at 2C with no signs of battery degradation." http://www.commonsenserc.com/phpBB2/viewtopic.php?t=14

FMA approves charging up to 3C with the Cellpro charger and REVOLUTION batts...thunder power and flight power now also approve up to 2C.(with the right batts/charger)....my FMA rev batts have over 325 cycles on them I've been charging at 3C since April and they perform like new.....we've been discussing this a lot on the HBK forum.......when charged with the proper equipment fast charging does not damage batts

So let me ask this! I am using a triton jr charger with a TP balancer. I currently have TP extreme 2200, is this a good batt/combo to charge at over 1c?

I know that the balancer and charger do not communicate, but I am unsure what you mean by "balancer in line with the battery".

Mr. Fender

This is big news to this noob!

I can charge @ 2C?

Charlie; Was that guy you quoted (I went and read it) an expert?

I also have a Triton charger with an Equinox balancer.

I'm sure it's good.

It was expensive and has lots of wires.

is the balancer in between the charger and battery or connected parallel??.......but if the charger and battery dont communicate ...I would think charging higher than 1C is NOT recommended with that set up........in order to charge at 2 or 3C the battery MUST be balanced while charging to ensure all cells are charging at exactly the same rate.......charging THEN balancing is not good enough for higher rates because cells could be charging at different rates and get too far out of balance during the charge

The charger is connected through the discharge lead and the balancer is connected through the balancing tab. The balancer is balancing during the charge but isnt connected to the charger. My balancer usually tells me that the battery is fully charged before my charger does!

I think I understand.

The Equinox IS in line between the charger and the battery.

It is a balancer with lots of wires to accomodate each cell.

Am I right? Experts: please verify

Fender,

I think I understand what you mean Basically I need an inline balancer to charge at a higher rate. Thanks for all the help and preventing me from burning my house down.

I think(not 100%)that you CANNOT charge at higher rates because the charge rate of each cell in that set up can't be controlled,the battery is being charged(discharge lead) THEN balanced....which is why the balancer is telling you the battery is charged before the charger....when one cell hits peak.the charge stops then the high cells are brought down even with the lower ones.........chargers like the CELLPRO4S charge through the BALANCE lead so each cell is monitored and charged individually........when charging this way at 3C each cell of my 3 cell batts are within .01 V of each other for the entire charge...if I am wrong someone please correct me

now that charge rates are getting better...chargers will be catching up fast and many more that charge through the balance lead will be available....FMA has a new one comming in Jan of 08..that will balance charge 2 3s 2100 mah batts at the same time in less than a half hour...I'm ordering one as soon as they are avail
