7.4v lipo help

[ikarma70]

Hi guys, I run 7.4v 1300mah 15c lipos on a kong power smart charger, how long do you leave this battery charging for please?

Does your charger have a RED and GREEN LED's ??

 

if they do then Red means charging and Green means charged. Just remember to keep an eye on the charger and lipo as it charges

[ikarma70]

Solid red for 2 hours

Mine charge in about an hour, should be some sort of indication on the charger to tell you when it is fully charged

[n1ckh]

That red light should change to green when charged

 

Leave the lipo alone for a few days for the voltage to settle in each cell then charge for 30 minutes and check the light

 

Do you have access to a volt meter or an Avo ?? you could measure the voltage in each cell then

[ikarma70]

Cheers guys, the battery was new.... Still got solid red ..... Taking off charfe

[ikarma70]

I think I may have a faulty charger!

I presume you are charging it via the small white lead, not the power lead for the gun?? If not then you may have destroyed the battery.

[ikarma70]

Only used the small lead for nimh batteries, I plug the lipo directly into the small 3 pin rectangular port

[ikarma70]

No white lead on my battery,, only the main connecting wire and the smaller plug.

 

I have tried charging other batteries but the batteries both lipo and nimh died quite fast hence my suspicion of the faulty charger.

 

I have ordered one on eBay, if I'm right I need a new charger and if I'm wrong I will have a spare and it's good to have a spare!

[ikarma70]

Tried again but this time I noted that the wall unit was cold as was the kong power charger and the battery too.

The red light was showing solid

The battery was plugged into the 7.4v port.

 

Upon on starting the charge . The battery shows a steady flashing red then goes solid, it does this on all of my nimh and lipo batteries..... Only conclusion I can see is that the charger is faulty.

[n1ckh]

Can you post photos of how you connect battery to charger and some close ups of the charger

 

Another possibility could be the wall plug

[n1ckh]

After doing a YouTube search

 

Indicator lights for type of battery connected

 

Battery knackered if continue slow/fast flashing

 

Solid Red light means charged although the bloke didn't say what colour the light is when charge complete

[ikarma70]

It flashes for a few seconds then goes to a solid red, green light should show when fully charged but doesn't even after a few hours

Hmmm, can you check the voltage of your lipo ??

 

I'm just wondering if your lipo maybe under charged

[ikarma70]

I believe I did that and the multimeter registered just over 8v.

[n1ckh]

Then I would say your lipos fully charged

 

Take a NiMH and run it down, leave 24 hours for the voltage to settle then put it on charge

[ikarma70]

And my other nimh batteries too?

[Esoterick]

I have one of those and the light blinks maybe once a second whilst charging and stays on continuously when charged. In both cases the light is red.

[n1ckh]

You can do but I suggested only 1 just in case the charger is knackered, if it is then you still have other battery's to use

[ikarma70]

Yes I do .. Very true and I have ordered 2 new chargers, one just for lipos and the other is combined.

[ikarma70]

Got my new chargers and the tomtac lipo charger went for about 1.5hrs and the 2 cell lights went green so I seems like my kong charger was the problem.

 

The IMAX b6 is currently charging one of my nimh batteries.

 

I would like to say thankyou to all that helped me!
