lipos not fully charging?

Hi,All of a sudden my turnigy 3300 4s charge up to 85%,not 99 or 100 like they did a couple of weeks ago,i have some overlanders which are only charging up to 45% too,when they are fully charged,puzzled!!!

Are you balance charging them?

yes martin.i dont understand it,its just started doing it,theres no faults coming up,and it flashes full at 16.80v

Where are you getting %ages from ? A battery checker ?

Can you monitor how much your charger puts back in, my ones give a figure for this. If so discharge a battery ( run the motor for 5 mins) and see if the charger replaces what you've taken out. if this is spot on or near, then it's your checker.

HTH

okay

I am 100% sure that Percy is a Cheeky Chappie, don't you think so Paul....

hahahaha,whatevers going on its doing my head in now,must be an intermittent fault with the charger,as its coming up with a fault saying reverse polarity,then connection break,but all leads are correct,i just dont get it,may invest in a quad charger,rather than use a para board,the sky rc Q200,Looks a good set at 160 quid.

i currently have the overlander rc6 vsr 80w 7 amp,a top selling one for around 45 quid,ive had it just over two years,must be time for the bin maybe!!

you get what you pay for i suppose gents!

Methinks it’s time to replace your balance board

hi trevor,ive tried charging them separately,and still goes into fault.

its funny really,when i give it a bang on the work top,it starts working hahahahaha,there are no loose connections,so has to be an internal fault

If in doubt give it a clout.....................

It does sound like it's time for an upgrade Paul.

On a serious note tho, you do have to look after lipo's, cos they can burn your house down Matey.

Take care buddy.

yes cheers dwain,i keep checking on them,whilst on charge in the garage,i put them in a lipo bag while they charge,helps i suppose.

Good Man.

Please, the correct terminology is 'percussive maintenance'. I seem to recall the Apollo spacecraft had a rubber hammer on board for just these sort of tasks.

I've always known it as the technical tap.

Anyway.

I've gone through two rc6 chargers, they've simply expired when used within rated capacity. I don't think they're that great build quality.

It was 'impact technology' where I was.

Problem solved,i have invested in a sky rc Q200 Quad charger,its the dogs,you know what.
