Lipos in Laptops....

[mgjackson]

We play with LiPos in our helis because they're powerful, but I thought they were a bit too risky to use elsewhere.

However, looking at the spec for the new Archos 9, it would appear to be using them:

Archos has been using LiPo cells in their devices for years now same for a lot of mobile phones.

You'll find them used when the design calls for a flat cell.

If round will do then Li-ion is preferred.

The main reason these cells are 'risky' for us is the fast charging and the slamming them inot the ground at high speed parts of our usage :)

Archos have had them in the stations for ages.

I have had mine for a good few years and its wank, unlesss you keep paying for the constant subscriptions you need.

Browse the internet using your own wifi - Subscription
Record TV (which is its sole selling point) - Subscription
Use the already built in feature of being able to download all the TV channels for easy recording - Guess what....... Subscription..

...the list is never ending!

My old MacBook Pro is LiPo powered, I know as it puffed and nearly killed the laptop.Most mobile phoned use them too and F1 cars.

Really? I don't know anything about the Archos or their services, but the Archos 9 appeals as an alternative the iPad*. Just assumed it was a small pc.

*Apple have named it after a sanitary towel because you have to be a bloody c__t to want one! :-)

Yeah my old Macbook Pro Lipo puffed and took the motherboard, screen and half the case with it. Luckily I got it fixed for free.

My wireless Plantronics CS60 headset has a LiPo in it, a single cell 190mAh. That's at least 3 years old. My keychain spy camera also does, but that's maybe not so surprising.

As already mentioned, Apple Macbooks have been using them for years. In fact, I think the first Macbook (as opposed to iBook) was LiPo powered.

it's not the same, consumer LiPos are much lower performance. You don't put a 40 C LiPo into a mobile phone, the requirements are totally different.

That's also one reason why cheap noname phone replacement LiPos from China can be a real safety hazard.

Often, consumer LiPo packs contain active safety circuitry that bricks the LiPo, once the voltage gets too low. It simply refuses to charge, and you're forced to dispose of it.
The reason is that deep discharge can damage a separator foil inside the cell, and that may lead to a short circuit later. With heli LiPos, many people (beginners) deep-discharge and keep using the packs or at least try.

I think you may have misunderstood some parts of the Archos offering :)

The only thing that requires an ongoing subscription is the TV listings service, you don't have to pay anything to record from your own TV if you are happy to set up the recording manually.

With the other services, depending on which model you have, there is a one-off (small) payment to activate some features that not everyone will require, certainly no 'subscriptions' to pay.
