Yeah I ordered the Turnigy Accucel-6 50W 5A Balancer/Charger I hope I made a "good" choice, I am going to be bummed/pissed if I ordered junk!... and no one stopped me!
Now that I think about it, any one know for sure that the rhino batteries can be charged with the charger I bought? The description says it will charge zippy packs and others.

rhino, zippy, loongmaxx, and alot of battery's have the jst-xh tap so you will be fine. thunderpower on the other hand are differnt.

Hey guys I got all my lipo stuff today.
Do the batteries come charged? My batteries are 11.1V shoud the charger stop charging at exactly 11.1V? It says it will be complete when the batt is at 12.6V?
Anyone give me a hand on setup on the charger the charger is a Turnnigy Accucell-6 for Rhino 11.1v 20C 3s 1550mah batteries Will it automatically stop it self when it charged the battery?
The power supply I pulled from a pc is only giving me 11.03V ( it should be giving me 12V) ca it get me by for a bit you al think?
Thanks
George

your batteries need to be charged to 12.6V. cells are full at 4.2. 4.2 x 3 = 12.6V total pack. i had the turnigy and it was my experience that it will continue to pump juice. its not a super high end charger, but it gets the job done. never charge a lipo and expect the charger to stop unless you know for sure.

what is the low voltage cutoff? (that would be the point where the lipo is considered dead or discharged?) PLEASE correct me if I am wrong Thanks admiralev  |

LVC (low voltage cutoff) is where the ESC stops the MOTOR draw from the battery (lipo or NiXX). The LEVEL is set differently for the 2 chemistries since they are different devices.
LVC is 'generally' set for ~ 3.0v/cell for lipos for most ESC as long as you ARE in lipo setting. Don't make the mistake of being in NiXX setting or LVC will be too low.
The LVC will be for an UNDER LOAD lipo. If you take it off and test it (resting) it will read higher. Best to never go below 3.7v/cell resting.
Good lipos should come partially charged, ~50% capacity
A good little chart:
4.20v = 100% 12.6v
4.03v = 76% 12.09v
3.86v = 52% 11.58v
3.83v = 42% 11.49v
3.79v = 30% 11.37v
3.70v = 11% 11.1v
3.6?v = 0% 10.8v
HOW LVC is set is completely a function of the ESC. You have to refer to the instructions. YOU SHOULD read them and understand them. Some ESC are very good, some good, some mediocre, some pure garbage, though where this line is varies a LOT for people.
This is an item of discussion but I believe most lipos should be treated 'nicely' the first 4-6x out.
Fly them easy (low amp draw) and don't take them below 50%. Hard, I know, but it may increase the long term life. That decision is entirely up to you.
Can't help you with the charger or PS-use neither of those.

Well, with the power supply i am using only putting out just over 11V I can not get the perfect, 12.6V and 4.2V/per cell I am noticing thouhg on one of the batteries (brand new by the way) I am getting 4.14, 3.85, 4.14 I can not get the middle cell to match.
What should I do? Should I worry?
Thanks
George

some pc power supplys need a load applied to the 5v rail to kick on, this might be why you only seeing 11 volts. also it will still fully charge the battery even at 11 volts.
charge the battery up and fly it for 5 min and check the cell voltage again to make sure they stay balanced. might have been a fluk from the factory.

So should I still fly that battery? Hong Kong is a long ways away to try and return stuff.
Maybe using it some, and recharging will fix it?
On the Power supply I am aligator clipping to +12V (yellow wire) and ground (Black wire)
I also removed the jumper from the stock Rx/ESC
Flydver I am still using stock electronics, also this may sound dumb but what is the left side cloumn representing, LVC? Do I fly to the 3.7V is reached or the the 11.1V (I know sounds dumb, but just want to be clear is all.
4.20v = 100% 12.6v
4.03v = 76% 12.09v
3.86v = 52% 11.58v
3.83v = 42% 11.49v
3.79v = 30% 11.37v
3.70v = 11% 11.1v
3.6?v = 0% 10.8v
Thanks
George
