Thumbs down Never buy turnigy lipos!

I purchased 2 Turnigy Nanotech 5000mah 2S 25C lipos off HobbyKing...finlly got a chance to burn through a couple of packs.

Temps only hit 100 degrees after each run. After that the cells would not balance when charging. I have to use my Hyperion 0606i to NiMH mode for a few seconds and then switch to Lipo mode and charge.

Anyone else experience this? I'm about to contact HK do they have some sort of warranty?

I've had about 15 of them from the 900 to 1300 range , a few puffy issues but never a balance problem.

x2. For the price I've been really happy with them and have had better luck than with hyperion.

Yes. They have a return / warranty policy. Here's the catch. You need to register that you received them on their website within a certain amount of time of you receiving them. I think it is 30 days. My friend did not do this and was rewarded with a LiPo paperweight. He has bought 4 batteries from them. 1 was bad. A 25% failure ratio is not good in my book.

Hope this is not bad news for you, and good luck.

I have a lot of Turnigy Lipos, both 2 and 3 cells. Using them in crawlers (from Losi Micro to 1:10) and in my Short Cource Slashes (2 and 4wd). No problems at all. Some of the Lipos are very old and everyone is well balanced also when drained to cut-off limit. I'll probably not use any other Lipo - price taken into account.

So are you having two problems or one?

"After that the cells would not balance when charging"
Are they tripping the alarm as soon as you plug them in, OR are they tripping the alarm sometime during the charge cylce?

Because this :
"I have to use my Hyperion 0606i to NIMH mode for a few seconds and then switch to Lipo mode and charge"
Sounds like your pulling the battery below the cell limit during run and trying to zap it so it doesn't trip a low voltage alarm at the beginning of the charge.

I'd double check you voltage cutoff on your ESC.

I have been using the HK batteries (Turnigy, Zippy, Flight Max, Rhino) for over 4 years now and in all that time and close to 100 batteries have only had one that had a bad cell.....for the price they can not be beat!

The problem is likely in the way you run and charge them or with your electronics settings....not the batteries

Same here, batteries from 1S 120 mah to 5S 5200mah and only had one pack go bad due to a broken internal contact.

Was the air temp 100 too? I have never had a pack come off that warm even when overgeared.

Another positive experience here. I've had about 15 or so turnigy packs from 2s-4s with my only issues being user operator errors. Apparently I'm on the lucky side to this day.

x2 on the curiousity about the nimh mode. The only time one would need to do that is because of running it down past 3.0vdc per cell and the charger wouldn't recognize the pack.

Yea I probably have close to 20 packs of varying age up to 2 years old and all of them are going strong. Sounds like you LVC is too low.

i have a hunch it's not the battery. I have had great results with my turnigy lipos. If you don't have your low voltage cutoff set right, you will ruin them right out of the gate by running them to low. That's what it sounds like is happening.

User error..


I own plenty of turnigy packs as well and no issue with balancing.. sounds like you are over discharging the packs..

I have 2 of their 4000mah 30C 2s packs that work awesome in my go fast bashers. One has puffed a little and started to split the plastic casing, but it works fine and still takes a fulll charge.

I have 3 of the 5000mah 20C 2s packs for my scaler that have been submerged many times and still function fine.

I also have 3 of the 2200 20-30C 2s pack for my crawler that work very well.

For the money, it is hard to complain!

guess you shouldn't have titled your thread this way...just sayin'...I don't personally use them but I have plenty of friends that trust them in their planes, a lot to be said for that...

Wow lots of replies!

I'm using the Turnigy Nanotech 2s 25C lipos on my Losi XXX-SCB outfitted with Castle's SCT 1410 3700kv combo.

Outside temperature was around 95 degrees. ESC temp after a full pack was 126 degrees and the motor was at 114 degrees so nothing was overstressed.

Lipo batteries hitting 100 degrees isn't too bad of an issue it was still warm to the touch and it wasn't even puffed. The weird thing is one of them puffed several hours later. I guess I need packs with at least 35C?
