Lithium cell tests

[swanaldo]

i am not happy with my last post on this thread and will be writing a mail to the fighting robots association

Edit ......isnt an aeroplane should really read... a RC Aeroplane or Car ....Reference the RC Groups link of my post.

Apologies, I did mean general use meaning to the general robot population.

Is it possible to put together some formal guidelines for the testing and introduction of new technologies to the sport?

[maddox]

Gary, what do you call new technology?

When hypnodisk shattered Stealth in series 3, the disk weapon was new technology
Antrax/Raven and Behemoth were among the first to use NiCd 7000 mAh cells. Equally new.
When Hardox was introduced in RW, it was new technology.
When Gravity started flipping in Heat D series 7, it was new technology and dangerous too boot.

When is something new technology? Or when is it just cunning use of existing possibilities?

[typhoon_driver]

When it isnt included in the current rule set

I would class the A123 cells as new technology as it is a completely new cell unlike any before

2.4ghz radio is another example

Just to put things in context,

Terrohurtz hits you with an axe not batteries

[grant_ploughbot]

But it pushes and drives with more batteries, and leaves weight for a heavier axe head.

[andy_kane]

The terrohurtz team are not changing anything but batteries.
And therefore will be weighing lighter than it usually does.
To keep bringing the integrity of this honorable team in to question is surprising to all who know them.
John is doing this testing on behalf of us all.

One of the main areas of benefit is going to be the featherweight folk.

Just to put things back into context.
Kan Opener squeezes you with battery power.

Both the above statements .....mine and Andys are really irrelevant to the original concern about weight.

All A123 battery testing Robots should.. IMO .. weigh in at the Championships UNDERWEIGHT by some 2 or 3 kgs ...thus proving that they have ONLY replaced their original batteries with a like for like Amp/Hr rating ....thus gaining NO appreciable power advantage and also showing that extras havent been added due to having a couple of extra kilos spare.

Alternatively ....If they really want to be top limit on weight ......A couple of housebricks tapped inside should be OK for ballast

One of the main areas of benefit is going to be the featherweight folk.

I thought that the A123 Batteries were legal in Feathers?

Until further notice, Lithium rechargeable batteries may only be used in robots in the Featherweight class and below

The testing and results supplied by John are of course extremely welcome.
