Vader says 'Yes' to LIPO

LIPO's are the future.

So, why do so many say 'No'

Because there is such a randmomness on build quality, safety and useability of the cells. Until a construction rule in place, they can be as safe as NiMH or as dangerous as an old live WWII bomb.

Surely companies such as Team Orion, FlightPower and now LRP have 'safety tested' their products before they sell them to Jo public?

Has anyone ever experienced any problems with any of the following products:-

1. FlightPower Trakpower 4900mAh
2. Team Orion Platinuim 4800mAh
3. Team Orion Carbon 3200mAh

I'm sure as with everything, if the batteries are correctly used there shouldn't be a problem. Same for Nitro fuel etc...

But the problem with LiPo is, that with every new generation of Sub-C cell, you could still get away with your last charger, with LiPo, MOST won't be able to, simple as, and to try to do is just a disaster.

Also, just do a search for LiPo on eBay, and the amount of uncased gel packs you can buy, this is where safety and construction regulations laid down by the governing bodies will need to come in play. As the current situation stands, if a club or championship series allows LiPo cells, you could easily turn up with a seriously sub standard cell.

Also, the cells are all rated at different discharge rates to. So until there is a specific construction regs, it is open to some serious H+S issue's. I can also see that the BRCA might recomend a charging pound, so if there was an issue, chances are, most are out of the way.

Don't get me wrong, I am not against them, and will make a fundamental change in the way we race elecrtic, but I don't think for the slightest, that companies will start to find ways of 'matching' cell performance.

they are not understaood

i have 4 trakpower, and loan em out at the sheffield biws, i run one pack myself, and have had no problem. i took a front corner completly off my xray while flat out on the straight, lipo was fine

chargers can be had for £30 ish

clubs are covered by the brca to use em (insurance)
the best way is to only allow packs in manufactures casing

some of us (trakpower drivers) were asked to abuse our lipos while testing

this ranged from charging at 10 amp (lipo only charger) and hard hits/jumps.
no problems at all

three main rules with lipo
only use lipo charger
dont discharge below 6 volt, some speedo's have this feature, device can be bought from novak/trakpower
let em cool if warm before charging

DCM i would hardly class nimh as safe! a young lady on rcracechat has poss lost one eye and had reduced vision in the other, from nimh exploding.
the current 4200 are poping like WWII bombs!

i heard it was a lipo at ameeting today please confirm this as you probably have the most valid argument for legalising lipos then also dont u think there is an econaomic factor in not making these things legal for use ie u dont need five packs of batteries to race just top up the lipo and mr modelshop if there are any left sells u these products
