You think? It is a same type of battery at a normal charge rate. OK, the cause is a simple swallow of the pack hitting a sharp edge on the inside of the phone.


On that Protek battery that can handle 10C charge:

4 or even 5mm connectors are not able to withstand such a high current. Even the soldering inside the pack as the small aluminium solder tabs will burn through at 490 amp.

So you do trust the 10C charging rate with a mentioned 100C countinious(!!!!) discharge rate.

There is no battery that requires any sort of charge rate, charge rates are entirely up to the end user. All I am saying is that if a battery manufacturer claims a max charge rate then it is entirely safe to assume that the battery will more than likely not erupt at that rate any more than it would at a lower rate.

FYI, my ThunderPower 6s 5000 packs were rated to handle a 60amp charge rate (12C) max and I did so every charge for well over 200 cycles with no noted decrease in pack performance.

Not a safe assumption. Higher rates will always have higher risk, even if it's within the rating. They've calculated a charge rate that fits within a safety margin they've deemed acceptable.

1 does not make a list graphene pak is not a lipo pak..

xpress what charger did you charge those 6 cells paks.with 60 amps.

you missed ...

what company sells a charger for a Samsung Note 7 that will produce more then 5 amps.... into a note 7.

I am sure the PORT on a Note 7 is very limited ..

True, but that is why high voltage charge adapters are introduced for quickcharging.

The phone will do a 2amp normal charging from any 5v charging adapter. But the quickcharge protocol sends some info to the charger so it can switch to 9 or even 12volt (if it is capable to do so). The high voltage will be lowered in the phone with a switching power supply to convert all the power to a higher charging current keeping the 2A max on the micro USB port.

All true. Though the Note 7 had a tendency to explode regardless of whether it was charging or not.

Here is some more info on the Note 7 failures.

I wonder how many people went and bought the Note 7 phones after the issues they had, same with high charge rates as I don't know about the rest of you guys, but I would be super pissed if I had to spend weeks cleaning my stuff because some guy was charging at a stupid rate and had a fire as if he thought it was good, as one of my racing buddies will charge at 15 amps and even then I questioned him on it as no clear reason as to why, so if you race around me or my family and want to charge at high rates, you will get talked with, and chances are very likely YOU will NOT pit by me.

As I have a bumper sticker on my van " I hate stupid people " and this applies to this safety at the track, this is just my opinion on this topic, Been racing tooooooo many years to have a serious issue at the tracks.

What has happened with the Note 7 can also happen with our batteries. The cells are also tight in the hard case and do swallow what can cause a wrong pressure on the cells.

Charging (and discharging) on high currents is giving heat can be a higher risk than charging on a lower current.

Wow... You guys are scaring me...lol... I'm not an electric racer ...yet...


Pass you soon...

It is not about scaring but some people do think too light about prevention.

It is not about all those moments it goes without an issue but only that one moment it can go wrong. An exploding LiPo and its fire is heavy so thats why always a good LiPo bag to charge, discharge and store.

had a 3 cell 3200mah 35 c battery go up in my mini 8 when the esc stuck wide open..couldn't get the body off face enough.. swell hisss.smoke n flames in under 8 seconds.

- Charging at higher amps, overall does not take more power. It will take more amps, over a shorter time.

- Of course charging over 10 amps is not as safe as 10 amps. charging at 9 amps would be safer than 10 amps. But then again, charging at 8 amps would be even safer?

Would like to see more facts, or maybe ROAR rules nationwide.

For me, if someone is charging at high enough amps, to lower resistance, in my stock racing class, I may do it also.

I was expecting this thread to be about indoor racing, 4x4 short course with massive power. Corner marshes tend to pay more attention, when we come out to race. :)
