Hard case or shrink wraped

[G-UNIT]

What do most perfer, hard cased batterys or shrink wraped? advantages/ disadvantages.
and what does roar approved mean?

[Rich]

I go with shrink wrapped because they are a bit smaller then their hardcase cousins. Also, if i have a problem with the wires comming loose i can resolider them easier. R.O.A.R approved means they are exceped by the racing asso. as spec for certain classes, someone can get into more detail than I about that.

Thanks Rich I was just wondering what people think and I have puffed some heat shrink battery a bit and they cooled down to normal size and hard case just split apart not saying there any good any more but just an observation.
So r.o.a.r batterys are not really any better the non roar batterys would you say this is a true statemant?

[Rich]

Yes I would say they are not different than each other. What lipos and what setup are you running that is causing them to puff? I am curious.

I think the ability to see if the packs has puffed slightly is an advantage with wrapped batts, but having said that the new hard case nano's looked too good not to try out so I have some one the way, 2s2p 6000mah 65-130c for $39. Sure you can't believe the claims of a lot of batts and you get what you pay for, lots of people are happy with their turnigy nano's and lots of people have had issues so time will tell=)

With boats you generally want to stay away from hard case packs for 2 reasons, they add unnecessary weight, however little it may be...and...ff they get water inside, you may not know it and they won't dry out as readily, which could lead to corrosion of battery connections, etc.

Rich, on the puffing, I can't say its the batterys fault, they are old with alot of cycles on them and also running them in a 5s configuration when there sopposed to be run in a 4s setup, also to much prop an pulling to much amps.
they are flightmax (zippys) 5000mah 40c ran in a UL-1 on 5s with a cut down m447 to a m446 with spooning and cupping,
the prop is a beast, just pulls to many amps for old batterys. I did hit 56.8 mph on the gps and it was a wild ride, the third time out with this set up the boat picked up a piece of plastic bag on the rudder and caused it to pull even more amps when I was bringing it in and the battery puffed so bad it sounded like jiffy pop popcorn in the boat and also smoked the esc. Live and learn.

[Rich]

I see, that would cause the issues you have. 5s in a UL-1 and your only getting 56 mph, I would have expected more. Then again like you said live and learn. Are you using the stock motor and esc?
