i didn't really pay that close attention, but someone at the track and a adapter they made to balance charge, if i remember correctly they took and servo plug with three wires one had a neg bullet plug, one had a positive bullet plug, the other had the small bullet plug for balancing. it was all plugged into the 2s balancing plug on the charger, i would imagine that if you took a voltmeter to the charger you could figure out which is positive and negative. the center should be the balance wire.

I have a better idea, don't worry about balancing the LiPo

Ok, I've a Core20 charger, with lipo charging/balancing, and stupidly bought a maxamps saddle pack (for a B44), with hyperion taps, and dont seem able to connect it to the core charger!!!!! None of the leads fit. Any ideas?
TIA,
Matt

The Maxamps balance plug is different than the Core's

The Core balance plug is JST-EH, I'm not sure what Maxamps uses, you may want to ask, then either wire yourself an adapter, or look at places like allerc.com for adapters.

Heres a good how-to for a balance tap for Orions/Trakpower for a LBA10 or just about any other balancer.

I did this for exactly the same reason as you and it has been fine, my lead is now about 20cm long

Obviously it voids any warranty, and I can only stress to DO ONE WIRE AT A TIME SO YOU DONT ACCIDENTLY BRIDGE THEM!

ok im curious if i buy a second set of connectors and cut them up does it still void my warranty as the charger and its leads are still perfect?

I need some help, this is what my core pack looks like. I have only ran it two weekends, and I only run it once a month, I put it on the charger about a week ago just to put some juice in it. I looked at it today and this is what it looks like . I am worried about the thing blowing up. Also worried that $120 is down the drain. I charged it like normal, I have an Ice charge set for 5 amps. Any help would be appreciated. I also need to get my bottom weight off, any suggestions?

you dont need to worry about it 'blowing up'. Lipos wont explode like a sub c pack. Instead they puff and sometimes puncture causing a chemical fire. They flame up, as some people call it.

so you put it on the charger, walked away, came back and it was puffed?

or you charged it, it looked fine, and then not connected to a charger or anything, just sitting it puffed?

I've never heard of the latter. For a lipo to puff, i think voltage has to be entering or leaving the battery. were you running it on a esc with the correct voltage cut off? You sure you had your ice setting to 5000mah? If you didnt have the mah set correctly and overcharged it that will happen.

Needless to say, the battery is toast, and should be discarded. Pry off your weight you have stuck to it, and dispose of it appropriately. If you are worried you could soak it in saltwater for a few hours before handling.

It was not hooked up to anything, I charged it monday, disconnected it and let it sit, I leave it taped into the car, but it was not connected to the speedo.
I have all the settings correct on the ice charger. I haven't changed them since I purchased it.

I have a race next weekend, So I got the car out to rebuild it and noticed the pack as you see it.

Call Shawn or Adam at Schumacher!!

Setting the capactity really doesn't matter. The ICE uses a CC/CV charge method. It will drop charge rate @8.4v reguardless of capacity. I have mine set at 9900mah. This allows you to charge at a higher than 1C rate.

Now using a NIMH setting will allow voltage to go above 8.4v and cause damage.
