You beat me to it. I think that should be the most important point in this thread. When I'm sitting in the pits, I'm not necessarily worried about my batts (NIMH or Lipo) because I follow the mfg'ers directions and have a flawless 18 year track record of no battery explosions/fires. I'm worried about the noobs and the guys who treat racing more as a sport and less as a hobby. If we can't have one major event without shrapnel flying in the air, maybe it's time for all of us racers to come up with positive solutions for this problem that some of us want to ignore even though it's hurting the hobby.

The point is NONE of the BATTERIES we MIS-USE/ABUSE in RC are very safe!!
Thick headed? Someone please explain to this dude about my tendency to get nasty...
Now, it appears that with the sudden spate of NiMh packs that are blowing up in the "hands" of RACERS......not newbs, not "johnny come latelys" but experienced JOES blowing more than their fair share of sub c's and lipo fires not happening as frequently as some said they would (when lipo really started catching on), we dont have to ask about settings. Many of us know that people are packing the amps on when charging sub c's, causing many of the mishaps, explosions, ventings, projectiles and accidents that are occuring on what seems to be, a weekly occurrence. Maybe, just maybe, people who are charging lipos at specific amp rates per the mah of their pack should start applying this mindset to sub c's....kind of backward thinking, but, to not do so is as you put it...THICK HEADED! We adhere to charging principles to maintain safety, maybe sub c rules should be revised. A lipo can be charged at rates higher than indicated, but no one has really taken the chance....seems that many sub c users are taking chances and paying the price. DUNCE.

this is a serious question here....
when NiMh cells first came out, did people follow the charging instructions like people do nowadays with Lipos? if they did, then at what point did hobbyists become so ignorant to the manufacturer's instructions and start assuming safe charge rates? just like bxpitbull said, if only we followed the manufacturer's recommendations, we would not have any problems. i know this has been stated already, but it's the racers that are making this appear to be a problem.

Lipo has been out a while now, now all you read is "can I charge at 2C?" It's only a matter of time. Before long people will be charging @3C and it will be a "travesty" lipos will be spewing napalm all over the faces of innocent women and children. Sadly, we do this to ourselves. Enough is just never gonna be enough.

Since I have gone Lipo, I have never gone higher than the manufacture recommended charge rates. And the good thing about lipo, you can charge in advance, touch it on the charger and its ready to rock. Its low internal resistance doesnt fall off if left unattended for weeks like nimh. So weigh the facts:

Charge your lipo pack(s) the night before
Check before you leave the house
Charge at recommended rate because it hasnt trailed off by more than .10 volts, which is nothing
Run your race(s)
Perform minimal maintennace on your brushless set-up car, check for tweaks
Put your other lipo pack on the charger which is pretty much full, might need all of 10 minutes of charging at recommended amperage
Tape into car....RACE!

Charge your sub c packs the night before
Hit them with high amp rates because they can "withstand it" before your race
Hope they dont get too hot and vent
Run your race
Perform maintennance on your car. More than likely, you still run brushed, touch the comm, check for tweaks
Put your fresh pack on the charger. Low internal resistance with Nimh, it has trailed off, so you have to hit it with heavy amps to get it ready for the race. Oh, you have to do this because the other pack cant take a charge for awhile because they are still too hot from the last race.
Hope they (the fresh pack) dont vent. Yes, they are hot, strap em into your car.
Race....

Do you sub c people see the danger (hypocrisy) in all of this?!?!?!?!?

Or to rephrase. "Us true diehard racers will endanger others for that slight edge so a better driver won't beat us". Does that sum it up as accurately?

Well put Kuzo! And with sub c's doing things that might make them look "bad", you would think that some of the manufacturers would play some form of damage control.

Yeah I see where you come from too:
EDIT:
Image removed by myself

So tell me, any reports of your cells going off yet? If so, any injuries?

Edit: since my post makes no sense now - the image was to note I am discussing this with a battery matcher.

Doubt because the ultimate goal is to get the consumer to doubt the product.

In other words, it's not much different than information terrorism. To get people all riled up and fearful about technology.


This thread is just as stupid as the lipo is dangerous threads.
Some guys like lipo....and some like nimh.
Run what you like and shut up about it.

From what I remember, previous threads never really touched on "pushing your equipment to its limits for performance edge vs toning it down if it gets dangerous" aspects. It's a viable discussion on the hazards of our hobby and what risks we are willing to take in the name of performance.

If you feel I'm wrong, I'll be glad to bow out and leave this alone.
