Yes. Mine came that way. It's works fine so I just ignored it.

Ran a couple of these Trinity 4500 packs this weekend. One of them had the play in the case like previously described. The other one was pretty tight.

Packs seemed to work well. Don't have any discharge numbers but they were fine for my poor club racing skills.

I like the external balancer connection on them. Allows me to balance them with the same balancer/connector that I use on my other lipo packs.

The case halves are supposed to be loose-ish. Basically, they are doublesided taped to the LiPo battery in the case. This allows for some expansion of the LiPo cell in the event of an overcharge, etc without having the case let the cells build pressure from being restricted.

Those of you that are ambitios/brave can carefully pull the cases apart to expose the electronics and cells inside. Just use your hands and fingers - DO NOT pry anything in there as you can puncture the LiPo cells. Naturally this will void your warranty. :)

Once open you can see how the balance plug and discharge protection electronics are connected. On the packs I sell I obviously don't take them apart but on my own personal packs I remove the elcetronics, re-wire the balancing plug and hardwire a 12 gauge wire with Deans plug to the cells. I don't need the LiPo voltage cut-off for my race cars and there is some voltage drop across the voltage protection circuitry which I have measured to be about .10 volts.

Personally, I think these are the best packs to get if you are bashing or club racing and want to have LiPo performance and don't want to buy a ESC with LiPo cut-off built in. For racing, with the electronics bypassed they can be very competitive.

Did you happen to see any manufacturing markings on the lipo cells itself? I'm curious which company trinity are using for their cells.

Thanks

Part numbers are on there but no manufacturer name. I wondered the same thing. I'll be ripping another apart today to convert to race pack and will write down the numbers.

to confirm, the balance plug on the packs, are they compatible with hyperion taps? Looking very seriously at these packs.

The balance plug is an Align. I use the Hyperion EOS0606I AC/DC charger with the "XH" balance adapter:

I can check to see if the Align plug on the Li-Pro fits the Hyperion balance harness I have. I'll let you know tonight.

good question i would be very interested in knowing this also.

Cain, I just tried the Align balance plug on my Hyperion harness and it doesn't fit. You'd have to do some modifcation to either the balance plug or harness to make it work.

Appreciate the info. Will keep this in mind then if I chose a trinity pack.

We have used several of these and they worked well in the 2wd truck we race.

However when we installed them in a VXL Rustler we were able to make one good pass then it went into protection mode and put out 50% of the power.

We tried 3 different batteries all fresh of the chargers and they all did the same thing. We dropped in a Orion 3200, 4800 and a Trakpower and they all worked great for over 5 minutes.

I would question the discharge rate as I have not seen it posted anywhere

Alright sorry about asking this again, :weird: but has anyone used the astro balancer with these? Or can someone tell me if the astro is compatable with align/e-flight???
Thanks

Just received my TMeXpress pack (re-badged Trinity) and have a few questions.

I was originally told it was a hyperion tap. After reading this thread and seeing it, obviously it's not. Is there an adapter to go from this tap to a hyperion to use on an LB10 balancer?

Also the pack charged fine, but when I put it in my truck, it spins up fine and then shuts down completely. Turns off everything. If I disconnect it and hook it back up, it will come back on and then cuts off again.

I did manage to get a few minutes from it at one point but it then cut off yet again. I know it's nothing in the truck as my nickle packs work fine. So is it possible that there is a bad connection somewhere in the pack causing this? It's acting very much like a loose wire or something.

Thanks!

Are you putting the truck under a lot of stress? You might be hitting voltage cut off if you are. It prevents the pack from discharging completely. But it can accidentally trip if you put the pack under a huge load and the voltage drops down below a certain level. I don't think the Orion packs have this cutoff build into them.

Nope, this was unloaded on an 8.5 motor. I hadn't even put the pinion back on yet.

I did get a little better result by flipping the battery strap over and taking some of the pressure off the pack. But that concerns me as it will take a beating in off-road. If squeezing it in a normal battery tray causes it to cut off, what happens on the landing of bigger jumps, etc...

We'll have to see. Saturday I'll take it racing and see how it does.
