Yea don't give up on LIPO power, it has made electric rc into a more enjoyable experience.


You should just rememeber 3 things

Don't discharge below 3v per cell or 6v for the entire pack

Don't over charge

Have fun !

Maybe something like this might help? It's 23$

This is the Lipo Shield from Common Sense RC. Lipo Shield is a low voltage cutoff device which enables any ESC to be used with lithium battery packs. It installs easily between your receiver and ESC and provides a reliable 3.0V per cell soft cutoff to prevent over-discharge damage to your expensive lipo packs.

Best bashing lipo for the slash is the Trinity unit with the internal cutoff. It is a great battery for you kid running outside. My kid has one and it has been great

The Trinity is a great option and it works.

I have 1 Orion and 1 Trinity and didn't even realize it has the cutoff in it until it happened.

Was letting some buddys run my truck doing while helping do some adjustments and it just up and stopped on the track. The cutoff triggered and saved the pack from possible harm. I still mostly race with the Orion though.

I might have to look into that.

Tip: Cut one wire at a time on the battery leads. I've seen people tried to cut two at a time.

Actually the Traxxas connectors on a slash are as good as deans. He would be better off making a traxxas charge lead and leave it at that. Plus they are cheap. Just pay attention to the instructions when you build them.

well good news.
hobby said the lipo seems ok. he said to run it for about 5 min then recharge and do that for 2-3 cycles and if all is well then use it like normal.

picked up a couple standard 3300 nimh batteries for my son and found a nifty little tamiya to traxxas adapter than i can stick on my charger for 5 bucks.

so all in all looks like i learned a valuable lesson and it didnt cost me much!!

Default Lipo Sack

You should pick up a Lipo Charging Sack. They are fiberglass sacks that you would charge the battery in. Was at the track 2 weeks ago when one went up. Flames were about 2 feet high because the guy didnt have it in a sack. Thant and he charged it on Nihm not Lipo. I think they cost about 30 bucks if that. But it will save your house from going up in smoke. Just a thought.

Default Safe charging

I use a hand granade box to charge in.
I figure if its good enough to store granades in lipos are no problem.
The best bit is it was free.

Did you even read it before suggesting it?

The trinity w/ internal cut off is the way to go for Slash and Lipo

Hey guys...

I hope this doesn't start a flame war... But I wanted to give some of my experience with the Trinity Lipos....

Alot of the guys at my track as well as myself have had ALOT of problems with these batteries. Trinity Reference 4500's.

The cutoff in them will not allow you to use them on anything hotter than a 13.5 Brushless System. The current draw is too much and tricks the cutoff into shutting everything down.

Now... That being said.. They worked just fine in stock slashes and such. But don't purchase these if you intend to upgrade to the Vilineon 3S system. They will go into cutoff even on a fully charged pack everytime you nail the throttle hard.

I've tried them on my GTB with 10.5 in my T4 as well with the same results. One time I tried a 3.5 in my Slash on the GTB with these batteries and it wouldn't even MOVE before shutting everything off.

Another problem I've seen with these is that 2 of the guys at the track can't balance charge theirs because of the fact that the circuitry that controls the cutoff is bad and won't allow a balancer to read the pack voltage correctly.

Just a few warnings guys... Like I said.. Not trying to start a flame war.

-David
