View Full Version : LIPO problems

I've got a 450se with a stock align 11.1v and a true power lipo with the same specs. I'm charging these lipos with a triton jr charger. I plug the battery into the triton (deans connectors on both batteries) and the charger detects the battery and it charges. The align battery usually takes about 30-45 mins to charge then the charger beeps when it's done. The True power battery takes about 10 mins and it lasts less than 2 mins.

IMO both my batteries cannot be used after just about 5 flights and I need to find out if they really cannot be used/repaired/brought back and what probably caused the problem and finally what are the best batteries IYO for my rex.

Detail of problems:
On the Align lipo, it just suddenly stopped working. I realized this when after a normal flight (usually hovering as I'm a novice) I plugged the batt into the triton to recharge and it couldn't recognize the battery. Plugged the battery into the esc after and not an beep was heard. I never over discharged the battery. The connectors are good and strong but I'm not sure about cold solder etc. Please advise.

On the True power lipo, I realized I began to have problems when I charged the battery one day and it became a tad swollen. The usable time on that battery is just under 2 mins and it charges in about 10 mins. Could this battery be brought back by any means.

Basically I need to know if either of these batteries can be salvaged. I live in Trinidad and I just cannot go to my hobby store and buy new ones and both my birds are down. New batteries means waiting about 4 days for them to get here after ordering online. Most importantly I need to know if I'm doing something wrong so that I do not damage other batteries.

I'd really appreciate some advice here and thanks for reading all of the above.

What's the mAh rating of the batteries? does the charger have charging modes? on my charger I have to set the battery type, voltage, and charge rate. At 1C charge rate for a 2200mAH 11.1V battery it uses 2.2Amps. Takes about an hour to charge.
...also what balancer are you using?

Jermo thanks for the response.
The batteries are rated at 2100mah. I'm using the triton jr charger and I've got no balancer. The only other battery charger/balancer I've got is the one that comes with the blade CPP.

As for the charging modes on the charger, I'm not too sure what you mean but the charger can charge NiCads, Lipos etc. and you can set the battery capacity and voltage. However this charger also auto detects the battery connected and it always reads 2100 mah 11.1v so I assume that's correct because that's the rating on the battery.

Explain what you mean by 'charging modes'. DO you think I can 'bring back' at least one of the batteries?

no idea if you can bring them back but I wouldn't use or charge them until I got a balancer. If there's anyone else around with a balancer or charger that has a built in balancer I'd do that before going any further. just my humble opinion.

I've got the Eflite balance charger, how about that?

The E-flight/E-sky chargers only looks like a balance charger. It will charge until any single cell is at 3.7 volts so it doesn't overcharge, but possibly leaving it out of balance.

If you didn't set those mAh and nominal voltage values it sounds like you may be charging the packs in a NiMH/NiCd mode. If I'm not mistaken, the Triton Jr. only detects pack capacity and voltage in those charging modes. In the LiPo charging mode on the Triton Jr. you have set set these values yourself.
