Is this charger smart enough to stop charging when the cells are full? Or do you have to be around when the charging is done to unplug it?

It stops just fine. I've left it plugged in overnight, but I wouldn't leave it like that to be on the safe side. It's a 'smart' charger.

I *think* so, but I wouldn't leave it unattended overnight, or anything like that.Always charge in a lipo bag for extra safety. This one is good: Generic CoBean Silver Large Size Lipo Battery Guard Sleeve/Bag for Charge & StorageI try to keep the LiPo in the bag, and the charger *out* of the bag so that the charger doesn't get suffocated (passive cooling).It's not the cheapest charger or the best charger (or the most flexible), but it's in the sweet spot... best charger for relatively cheap.I had two cheapo chargers go out on me (the kind that is bundled with ready to fly kits) before I bought the Traxxas.

I would not reccomend leaving any LiPo unattended while charging period, no matter if the charging stopped or not. To answer your question more directly, the charger does stop charging when it detects that the cells are full, so the instructions say but I would not just leave them connected. These are very dangerous batteries.

I would recommend unplugging when not charging. I plug mine into the charger every couple of days while driving and it has never run the battery down dead.

It's up to you. It does not hurt the charger to leave it plugged in. But if you want to unplug it, that's OK too. I leave mine plugged in for convenience.

I do not have this charger anymore, but if I recall correctly: it will turn off. However as long as the battery is completely charged it is in my opinion just cosmetic. R.

No, this is not a "smart" charger. When you plug it in it charges for 10 hours and then shuts off. Period. If you put in fully charged batteries it will still charge them for 10 hours.

I leave on charging station all the time since it shuts itself down when fully charged. Does not affect the battery if I remember correctly.

How long is a guess. I guess it's too expensive to put in a voltage detector for shutting off the charger when it is at peak. Yes, you can charge with it shut off. It asks if you want to continue charging when you shut down.

This charger is quite smart. It knows when to stop charging. If the red light goes off after a few minutes, that means the battery in that charging channel is already fully charged. Do you have any reason to suspect that the battery is not fully charged? Only a dumb charger will continue to charge a battery for 6-8 hours even if the battery is already full.

you cant shut it off, but all the times I have used mine, the battery depletes fairly evenly, never had one or more cells totally deplete while the others had a decent charge. I have only used it on 3 cell and 4 cell batteries. works great. are you using a balance charger for your batteries? that's all I can think of why your battery depletes so unusual. if not, get one that will also discharge your batteries properly for long term storage. you cant store them fully charged or drained.

To be quite honest, I haven't paid to close attention. When I charge this charger, it is normally overnight. Once it's charge it does charge my iPod fully which is great, my phone if completely dead it gets it up to about 50% before needing to recharge charge.

It seems to shut off when full charge is reached, don't know the answer too second question.

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry.

If you try using it while it's charging with the plug, you won't be able to do much... In order to use the phone, you do need to unplug it...

I have a 2 port charger and I've never had a problem leaving it plugged in when not in use. I hope this helps.

Yes, it does prevent over-charging. This is accomplished by the charger switching to a type of stand-by mode when the battery is fully charged. Its LED display shows the specific cycle in which the charger is operating. If the battery power drops to a level below full charge, the charger switches to charging mode to top-off the battery again. I am completely sold on this CTEK Charger! Also, it CAN re-charge a supposedly "Dead" battery, if the battery is still capable of accepting a charge. This is achieved through its "de-sulfation" (altho this is not the correct term) process.

Yes, it does stop charging after the battery is fully charged. Older battery generations such as NiMH need to stop receiving power after fully charged, otherwise this will damage the battery. But don't worry, the Tenergy Smart Charger will automatically cut off charge when battery is fully charged. This is why you see the word "smart charger" in the description.

Best to turn it off then charge it....don't let battery drain totally. I often use it plugged in when it's fully charged.
