e-Electric Batteries & Chargers > align rcc-3cx charger

i recently got a tp1320 3s lipo and the align rcc-3cx charger. i am a newbie, so this is the first time im handling a lipo. i bought an adapter so the tp1320 balance connector fits the balance socket on the charger. when i plugged it in today, i heard a high pitched tone. i took the battery out cause i thought it was the alarm going off or something due to reverse polarity. im pretty paranoid so i want to make sure if that actually is the alarm or not.. how loud is it supposed to be? the sound i hear isnt loud at all but its pretty high pitched and only happens when i plug in the battery. anyone else here have this charger?

Do some searches on that charger...........

I have absolutely NO idea if the statements are true or not (disclaimer LOL) but I have read that the 3CX charger is kinda dangerous.............most upgraded to the 4CX charger...................

how is it dangerous? i was under the impression it was pretty safe with its balancing and auto shut off features?

Again I may be wrong but the issue was with the original 4CX charger as it overcharges by up to 0.15V per cell or more in some cases. I have one of the original ones and it oftens charges to 4.3V per cell and I have even measured 4.4V once or twice.

I beleive Align rectified the problem and the new verison has the label NEW on one side. I have seen posts where people are reporting that the NEW verison is indeed rectified and charges the cells to 4.15V only.

The 3CX was introduced after the NEW 4CX and the only difference is that the maximum cell count is 3 rather than 4. I have no experience of this charger but do plan on getting one to charge 2 packs in parallel.

Also, I have read a post somewhere that the old charger problem only affect cells with high C rating (don't know why by it's something I've read, due to the extermely low internal resistance I recall).

Personally, I've been using the old original charger and have had 400+ charges from it. One LiPo pack lasted 120 charges (kill by me overdischarging in the end). And my current 2 LiPo packs have had 150 charges each, by capacity has dropped to around 80% (getting only 7.5 mins instead of 8-9 mins).

I would suggest always measure the cell voltages after charging and discharging to monitor.

I stand corrected.............thanks for the info trex888

You have cleared everything up. I also am VERY happy with my new 4CX as I stated

oh ok that makes sense. i will check the voltage of each cell next time i charge. by the way, i noticed something strange on the 2nd charge of my tp1320 3s. after about an hour, the middle light started alternating between red, green, off. it did this for the remainder of the charge. i thought that just meant its balance charging it. so i kept waiting, and about half an hour later the left and right lights turned solid green, so they were done. the middle light kept on going red, green, off. i waited and waited and after about 2 hours (total charge time) i said screw it im taking it out. anyone else have this experience, does that just mean its balancing the middle cell, and if yes is the balancing suppoosed to take that long?

Mine does that for both 2 cells and 3 cells. It has never taken me that long though. Maybe your pack was out that much???????

yeah maybe it was. so to confirm, you have seen you're charger lights blinking reg, green, off also? i just wanna make sure there is nothing wrong with my charger/battery.

thanks

It's sounds as though you batteries are on their way out. Do you use the TP1320 for a TRex? If so are you sure they have not been abused? 1320mAh sounds low and anything less than 10C rating would definitely be bad.

My Green lights on my packs always turn Green within 2-5 mins of each other when new. If not I start worrying and oplug and measure voltages. After 100+ charges they may be up to 10 mins out. With over 150 charges on the current packs they do what you describe; takes ages to get all three lights to turn Green. However, I know with my packs that one or more of the cells has aged so much that getting to 4.2V is almost impossible (the worst cells get to 4V or 4.1V only). So, again by measuring voltages of individual cells I know when the bad cell would have reached full charge and plug manually. If I feel it needs more I plug it backin. There will come a time when this trick will no longer work because the good cells will be overcharged too much for their own good.

BTW, the Green LED turns back to RED because the voltage across that particuar cell has dropped back below the preset voltage of 4.2V and the charger kicks back in.

Did you cycle the packs? The first 3-5 cycles you should only use 50% or so. Do that for the next 3 discharges and see what happens.

cycle that packs? whats that..

im actually chaerging it right now and this time both the 2nd and 3rd cells are flashing.. 1st one is solid green. im gona wait it out this time and see if the other two become solid too.

ok this is getting ridiculous. i plugged in my battery today around 5:30 or around that. 1st cell got fully charged first in about an hour or a little less. this time the other two lights starting blinking. the 3rd light became solid green after some time, so now the 2nd cell was remaining again. i left it for 3 hours.. blinking never stopped. again i got fed up and took it out. this time i pluged it back in right away. this time the 1st and 3rd lights were solid green as expected. after some more time, te 2nd light finally went green. i checked the voltage of each cell, 1st and 3rd were 4.22 and the 2nd cell was about 4.18, total 12.62.. could there be something wrong with the 2nd cell, how come it's a litter lower than the other two..

yesterday the battery did fall on a hard wooden surfacefrom about 4-5 feet. there is no visible damage though, could that have done something?

I'm new to LI-PO my self but I'm sure dropping your pack didn't help it at all. My LI-POs have a PC board on one end whereas all the connections between the cells and the pigtail leads are made and during a nose first crash in wet grass the impact cracked this PC board. In my case it wasn't cracked enough to damage any of the connections so it all still works, but (if your packs are designed like mine) in your case they may be.

align RCC-4CX charger red/green light blinking

I also bought this same charge and have used E-Power 3S lipo (http://www.helidirect.com/product_i...products_id=635) that has balance connector with similar problems where sometimes it would charge fine where in beginning, 3 right lights turn red, then all turn green when done. Other times (with same battery), one or more lights blink red & green after a few minutes. The instructions do not describe what this means because it's horrible English. I've done same thing when it starts blinking (unplug, then plug it back in several times until it turns red, and then green). What a pain. Had I known this would happen, I would never have bought this stupid charger. I only bought it cus the T-Rex heli is awesome so thought they should make good chargers...wrong...

Align Balance Charger

I have the align rcc-3cx balance charger and as far as i can tell is" When the red/green blinking light is flashing it is in pulse charge mode" to very slowly balance the cells, and it works like a charm. I've had 2 what i thought were lipo's ready to throw out, due to 3-5 min flight times until i got this charger(it took almost 3 days to get all 3 solid green lights) now 9-12 min flight times and my voltmeter is alot happier now!!!(lol) Very happy with it.

Align Balance Charger

dialtone,
Thanks for your input, although my 4CX charger has this red/green blinking light problem with all 3 of the Helidirect E-Power 1300mAh 3s lipos (2 of which were brand new) as well one Helidirect ProLite V2 2100 mAh 3S lipos (http://www.helidirect.com/product_i...products_id=858). This happens after each use and recharge, so it didn't make sense that this would happen to all of them. Three days to wait for one battery to fully charge (all 3 green lights) seems rediculously too long, especially if this occurs everytime. Why didn't Align instruction describe what this blinking means.

So out of curiosity, how often do you get this blinking light situation? Thx.

align rcc-3cx

I get blinking lights all the time, but only middle light 99% of the time. Of course right now i got a lipo that is only testing at 3.91 on all cells, but charger has all green solid lights. So i really don't know if something may be wrong with either the charger or lipo. I may have to buy a highend charger to compare with!
