do you feel safe at a track??
when a guy sitting 3 feet away from you charges at 40 amps or over 5 c like as in 8C..
i tried to make a poll but was unable to Yes 1 Heck No kick that VI out 2 I don't care. 3 would you feel safe marshalling that car no 4 me id say 2 and 4 I race at 3 tracks a week all have rules against Higher than 2 C charge rate they find you doing this your GONE.. |
The use of a LiPo bag is mandatory, then they can do whatever they want. But beside that, there is also a limited power at the tables, if everyone is doing that the main fuse will continious blow out. That is why most clubs have the 2C/10A max rule.

nope and that's not how our 12v or 18v dc ps work.. its SAFETY no popping circuit breakers AC is not DC..12v isn't 115 or 240

40A charging is getting close to 400W (once you factor in the fact that the DC power supplies are not 100% efficient). Add tyre warmers and you're looking at only 2 batteries per 115V outlet or 4 per 240V outlet before you're exceeding the AC mains rating.

The better clubs have lucky a 3 phase connection of each 16 or even 25A but even then the rules are limiting charging power just for safety and keeping the mains fuse alive.. |
400 watts at 12 v isn't the same as 400 watts at 120 volts.
A 700 watt power supply at full tilt is only pulling 10 amps on the mains cable. Plus at big events your going to have waves of people charging, not everyone all at the same time. Roelof your lucky in Europe with 220, your going to be pulling about half the amaprage us poor Americans have to pull. So our 700 watt ups would be about 5 amps at the mains. |

an extinguisher handy

This type of subject should be brought up at your local track as opinions will vary, as most tracks would have a fire extinguisher on hand, but can you imagine what the smell would be like, as few years back had a esc go up in flames in a small indoor track, and every racer that came in said man what is that smell, as I believe they should put limits on charge rates, and over all voltage, but I won't go their :flaming:

ok facts Fire extinguisher's don't put out lipo fires.. co2 nope dry chemical nope. Halon Yes but whoever is in after blast is dead as it removes oxygen in the gas cloud that the fire extinguisher's puts out(outlawed now in US and many other countries..a bucket of sand might hold the fire but will not put it out...
so now we are trying to max the ac plugs out with tire warmer heaters OK..lol.and a guy that abuses a lipo around me is not free to do what he wants ever NOPE not gonna happen. |
I don't pit next to retards that charge that high.

Tracks sometimes have limits and rules but u can't stand over people's head and police everybody. At some point you gotta trust that people will be smart enough to do the right thing but there's always exceptions . Those who do break the rules and get cought should get a time out from track the first time and banned after that. There is no good reason to create fires with unhealthy fumes for the rest of us to breath in and disrupt our day off playing with our toy race cars .
