Nick, I'm available to help with the building Friday evening. Or atleast laughing at you when you drop parts.
Okay this is probably a dumb question, but I've never had this happen. With Lipo batteries do you need to run them down before you charge them. For example I charged up one of my new batteries and played for about 15 minutes. I want to use the battery this weekend, so should I just charge them or what should I do?

You NEVER run lipos down. If you take them too far down the battery will short out. Speaking of which you need to have a cut out that will chop off the battery power when it gets to a certain point, do you have one of those??? If not I may have an extra. It is real important. Also make sure you have the correct lipo charger or it will go BOOM. :lmao:
Im sure you know most of this stuff but Ive been using these batteries for like 8 years now (rc airplane usage) and if taken care of correctly they last for years. (If not--- seconds). Ive seen rc airplanes burn to the ground due to general missuse and lack of knowlege. Read up on them. Im sure there are tons of threads. I can answer most questions in regards to them.
I usually keep them topped up at all times. They hold a charge real well when not in use. They do not like cold and will discharge just because they are cold. I like to keep them in 60-80 degree surroundings and when not in use are usually in a Lipo bag. It would be a bummer to come home to the house in flames due to something so silly as a lipo fire. They really should always be charged in pottery with a cover or a lipo bag. Mind you I am guilty of not doing this. But I NEVER charge them unnatended. Many a person has lost a car or house this way. I keep a fire extinguisher in my "airplane" room but to be honest it wouldnt do much as it is kinda like a sparkler when it goes off and will even burn through cement. Basically treat it with respect and all is well.

Jeff as long as ya have your lipo cut off on your ok! But I never store my lipos completely dead ( lipo cut off dead) . Dansam check out some more lipo blow vids We have plenty of them on you tube. We blew up tons of them last year . 80 amp start on a smart charger will throw FIRE! Plus jay will show how to destroy a lipo in no time Flat.

Jeff i think your thinking of "cycling" them. You don't need to with lipo's. Also i don't remember if we turned on the lipo cutoff or not. If you notice its starting to loose power stop running it. Thats about the point the cutoff kicks in. To store them (weeks or months) its best to leave them about 50% capacity. I usually just charge mine the day before we run at nicks or where ever.
I only blew 4 or 5 up if you guys go to larrys take pics/ video please

Its all good. just spreadin the Lipo Gospel. Ive seen some fail, and not on purpose. Had one guy lose a plane in a ball of fire (was really cool to everyone except to the guy who had to pay the bill). 400.00 gone in one flight couldnt even save the electronics.
in other news,,,,,
Cant wait for this Sat.
Made some mods to my trucks bumpers and lowered the battery so I hope to see some improvement.
So far lovin the truck and the forum "thumbsup"

This is not true. If you over discharge them beyond the 3v per cell the issue becomes the chemicals inside lose bonds and can no longer be charged. This is often called a dead cell issue (can happen because of over discharging, or cell quality of chemicals).
You can get by without...though for scalers and bashers it becomes more necessary since you guys run them longer, not just short 4-5 minute courses. You can do the run until it feels slower but you are taking a risk.
This is a must...again not sure on the heavy exploding idea. Typically they just swell and you'll see problems and have plenty of time to get it outside. I've seen a pack set on 5amps on NiMH for 45 minutes...all it did was swell. This was an accident by the owner but there was no fire, smoke and definitely no explosion.
Again thats a myth. They do not discharge, their chemical structures become weak lowering effective cold temperature voltage, but as soon as you bring them back to room temps the voltage will climb back to what it was before it was cold. All about the chemical structure and internal resistance at temperature levels.
I charge them open air all the time and I have charged them completely unattended many times. Key is the right charger, good packs/cells, proper charging amperage and a balance charger helps even more. Also do yourself a favor and spend money on a charger of high quality (not cheap chinese crap) and good batteries with quality cells.
Most issues (old airplane issues) came from not understanding C ratings and amp draw, over amp draw any type of battery and it will destroy itself. Lipos have come along way in C and quality materials and brands keeping the quality levels high to increase safety and use. I however am more afraid of the old NiMH packs which I've seen explode and catch fire more often in the past 5 years of racing than Lipos, easily by 3 to 1.
