SHORT CIRCUIT BATTERY PING

[TOYIKO]

Hi friends

Recently I bought a battery LIFEPO4 48v 20ah ping

When I used the voltmeter, accidentally,one of the poles of the voltmeter,causing a short circuit, It happened to me 3 times!!!!!

Does this could affect the performance of the battery?

Will I have less power?

Does the battery will die sooner than normal?

Sorry for my english!!

Thanks

A few small sparks like this is not a big deal.. ( will damage the volt meter probes but how much damage depends on how long the short lasted ) .. a few fractions of 1 seconds is not that bad.. if you short the wires for prolonged periods of time the BMS should cut the power safely.. without a BMS some serious damage could result..

Small sparks are not good, but ok. :wink:

The pack have B.M.S.!!!

I've done the same thing, my voltmeter leads are shorter now but the battery is ok.

ok

thanks for your advice!!!! :wink:

I shorted the wires on my ping once, and it did a good welding job before I riped the battery wires apart, and all this despite having a BMS that's supposed to protect it. I guess the circuit didn't respond fast enough to the rapidly rising current and switch off the MOSFETs before they self-destructed from internal heat. All four FETs melted... but I replaced them by better ones and they work great with less heat now.

As for the battery, it still dishes out all it's amp hours so I hope I will get away yet with my attempted murder!

Good thing we are making our boo boos on little 36 and 48 v bike batteries instead of leaping into 120v car conversions isn't it? Expensive enough as it is without adding funerals to the cost.

I shorted my battery with around 50 volts of electricity for a few tents of a second(think big spark) with the negative wire on the BMS touching the positive terminal on the battery, and it won't run. It shows the correct voltage at the port, but it seems like it won't supply current. I found that I had a disconnected sensor wire, and I reattached it and checked to determine that it wasn't triggering LVC. After the repair attempt, it still won't run. What the heck?

Possible BMS is shut down, you can try to have a charge to see whether it works

It doesn't do anything when plugged into the charger. I think the BMS is just dead.

Has anyone else experienced BMS Cut-outs due to short circuits?

toyiko, do you really have a ping battery or is this the pack you bot on ebay last year? that was not a ping battery.

do you have a picture?
