Several people have posted that they have heard no bad things about Lipo. Yet the first 3 people I talked to have told absolute horror stories! I'm not saying don't allow Lipo, just let's be careful about this.

And someone said they spend $900 a year on batteries??? That's more than 15 packs a year!!! I know sponsored pro level drivers who don't go through half that many packs. I know you want lipo's, but watch the exaggerations.

NO!

In fact it's not safe charging any type of battery inside a car. Open the hood (in your case the bonnet) and charge there.

MrBlack,

Have you guys ever considered releasing an inexpensive "dummy" charger that complements the batteries you sell? Maybe it's coddling the customer too much, but since the primary method of damaging LiPo seems to be overcharging, how about an inexpensive 1C charger that's got a locked setting specifically for a particular battery?

The concern with damaging a LiPo seems to be with new/inexperienced users more than people that have been around a while. To what extent, I wonder, does LiPo need to be idiot-proofed to appease governing bodies about the ability to use them safely.

I charge my transmitter LiPo in a Liposack away from other equipment. I don't know if its Chinese or what, so I don't take chances with that one. The Orion packs I generally leave on the table to charge like any other pack, on the table away from other things.

I store all my LiPo batteries in a Liposack during the week when they're not in use.

Do we know what kind of cells TrakPower uses? Are they cheap Chinese cells or something from a reputable manufacturer?

Exactly, watch the exaggerations...those horror stories...what specific LiPo were they using? The cheap Chinese ones or quality batteries like the ones offered by Orion/Peak? There is a good bit of info on the LiPo Awareness thread that maybe you need to read. I hear horror stories all the time regarding NiMh batteries too but they're legal. Just because something CAN happen doesn't mean it will and there are ways, through rules specifications, to make sure that only quality LiPo batteries are allowed for use. You keep saying things regarding racers knee-jerk acceptance of LiPo but it seems to me that you have a knee-jerk reaction in the opposite direction. Obviously you have a problem with LiPo...let us know what it is. Horror stories and telling us all to not be idiots is not doing anything.

The TrakPower pack uses cells from Enerland in Korea. They have fairly average manufactuing quality - not the best, but definitely not the worst. Most all the Enerland cell I tested have mediocre cycle life ~ 100 cycles. They tend to lose capacity from the first charge on.

Yes duralite, I have the balancer to go with it, although it's not doing anything yet as the pack isn't out of balance (only a month old)

charge at 1C and that's it

Says they are manufactured in Malaysia on the Trakpower website...?
