willb Posted June 19, 2009 Share Posted June 19, 2009 I need to buy a few LiPos for my brushless Slash. How well do soft LiPos stand up to some hard bashing at skate parks and places (easily 20ft jumps/drops)? Would I be better off buying hard cased?

joe of loath Posted June 19, 2009 Share Posted June 19, 2009 On a slash it doesn't matter too much, as the battery hold down is pretty sturdy, but hard cased are worth it. Quote Link to comment Share on other sites More sharing options...
Si Coe Posted June 20, 2009 Share Posted June 20, 2009 I've got both types and to be honest it you are careful there isn't much to choose. In a car like the Slash were the pack is securely mounted somewhere it won't get hit soft cased would be fine. However, decent soft cased packs are a rarity. Most are either ebay cheapies that don't last or meant for aircraft and slightly the wrong sized, not high enough C rating etc etc Quote Link to comment Share on other sites More sharing options...
jammi Posted June 20, 2009 Share Posted June 20, 2009 I dont use hard case lipos anymore your limited by mah and cell count also they tend to be pricer and not many companys make them I use maxamps, flightmax, turnigy, tornado, poly-pro, polyquest none of those are hardcased and they take a beating in my Slayer, Savvy Flux, E-revo etc. Quote Link to comment Share on other sites More sharing options...
willb Posted June 20, 2009 Author Share Posted June 20, 2009 I've just ordered 2 Turnigy 5000mAh 2s LiPos for my Slash at $20 each (not hard cased)! I'm going to line the tray with a small amount of foam to give them a little extra padding for the rough landings! For the price I paid I wont be too fussed if they die quickly but here's hoping they wont. Quote Link to comment Share on other sites More sharing options...
ebo Posted June 20, 2009 Share Posted June 20, 2009 I double heat shrink my soft lipos makes 'em nice and sturdy! Quote Link to comment Share on other sites More sharing options...
Garry Posted June 21, 2009 Share Posted June 21, 2009 I wouldn't go anywhere near a soft cased LiPo in a car without a home-made hard case used. Heatshrink won't stop a flying bodyclip or sharp bit of grit piercing it. I've seen triple heatshrunk NiMH cells have the shrink torn through in an Associated B3 and thats a close fitting body, and the battery well protected.... Not worth the risk at all.

willb Posted June 24, 2009 Author Share Posted June 24, 2009 The slash does have a sunk battery housing place so maybe I'll get lucky? I was going to line the top and bottom with foam so they are a bit better padded. Quote Link to comment Share on other sites More sharing options...
Thomas98 Posted June 24, 2009 Share Posted June 24, 2009 Hi I have never used lipos but the hardcase lipos look a bit brittle but what do i know. Quote Link to comment Share on other sites More sharing options...

I was going to line the top and bottom with foam so they are a bit better padded. You can cut foam with a knife....which is sharp... Its not about padding, its about protection from things hitting the pack and puncturing it. Hi I have never used lipos but the hardcase lipos look a bit brittle but what do i know. Nothing. Hardcase LiPo packs are incredibly tough. Quote Link to comment Share on other sites More sharing options...
willb Posted June 24, 2009 Author Share Posted June 24, 2009 Hmm... well for $20 a pack it's not a great loss if they're crap or die quickly. Will see how they get on. I could always fabricate a small cover to sit on top to prevent puncturing! Quote Link to comment Share on other sites More sharing options...
rcsammy Posted June 24, 2009 Share Posted June 24, 2009 i doubt anything would puncture it, would have to be very unlucky i have run soft cased lipos for almost a year now and have been bashing the rustler/slash pretty hard and have had no problems yet Quote Link to comment Share on other sites More sharing options...

bb2120 Posted June 25, 2009 Share Posted June 25, 2009 (edited) Soft case lipos are surprisingly tough, but obviously are more prone to being pierced. I wouldn't worry about using one if the battery tray offers good protection Edited June 25, 2009 by bb2120 Quote Link to comment Share on other sites More sharing options...
RC_NuB Posted June 25, 2009 Share Posted June 25, 2009 I need to buy a few LiPos for my brushless Slash. How well do soft LiPos stand up to some hard bashing at skate parks and places (easily 20ft jumps/drops)? Would I be better off buying hard cased? Hi Here`s my ten pence worth... 1) hardcase protect your battery 2) You could change car / buggy / truggy and the battery tray not be as protective so soft lipos wouldn`t be suitable. 3) Isn`t it best to be safe than sorry 4) There is no major difference in price Just my opinon i`d go hardcase everytime!

Thomas98 Posted June 25, 2009 Share Posted June 25, 2009 Ive already proved i know nothing about lipos so what would you reccomened for use in a 1/10 buggy/truggy with an Ezrun brushless set or can it even take it. Thanks Quote Link to comment Share on other sites More sharing options...
Garry Posted June 26, 2009 Share Posted June 26, 2009 Depends how much you've got to spend . Quote Link to comment Share on other sites More sharing options...
Si Coe Posted June 26, 2009 Share Posted June 26, 2009 Also depends on what you are after. A 5000mAh 15C pack would be fine if you want mega runtimes, but a 3500 30C will offer more punch and performance, just for less time. Quote Link to comment Share on other sites More sharing options...
jammi Posted June 26, 2009 Share Posted June 26, 2009 I think it depends on your application, you will be hard pressed to find hard cased lipos that provide power needed to run the MMM 6s with good runtime, as the motor needs 120amps and with the so 2x 3s hard cased lipos would be too big to work 5000mah at 25c min, but a nice TC could do fine with a 2500mah 20c lipo.
