does this look normal?

whippo · 07-09-2012, 03:00 PM

I bought a heli on HF with a couple batts when I got them one looked like it leaked? The seller can't remember what it looked like.. These are gensace 4800 6s 60c packs

thanks in advance

That definitely does not look normal... Abused perhaps. I would be hesitant on putting it into service in that condition. If you have a good charger that can measure the cell IR, then you can get an idea how far gone it actually is.

Ir on pack is 2 holds charge over 24hrs...

I wouldn't care so much about how long it holds a charge. The question is how does it do when being discharged. With an IR that low, the pack may be healthy still... But it sure does look abused in your pics.

I would fly it and see how it comes down after the flight. Check the cell voltages and the pack temp immediately after the flight. If it checks out, put it to use.

just got rid of a pulse pack that did that... one of the inner cell's seam had split and it was leaking that juice. take the heat shrink off and inspect it.

it should smell really foul once you take the shrink off

oh yeh and when i said a seam had split... i dont mean it was obvious.. i had to really inspect it. and found it there was clearly lipo paste exposed under the seam fold. and was the point of the ooze discharge.
also it would charge and fly fine but as soon as i noticed this i scrapped it... it could have burned my house down
