Trakpower Li-Po 4900
Got mine today from Microtech. The reason I bought this one is because it had the in-built corally connectors. I will be running it on Friday night at club.
So far it looks excellent! Really nicely packaged, and feels solid. Doesn't feel any lighter than my GP3700's at present, but I will stick them on the scales tonight to compare! Mark

The Li-Po weighed in at 266g, with connectors, and casing, while the GP3700 slammed that with a whopping 416g!!! What a fat bastard!
Well, I am looking forward to Friday at this rate, running the li-po all evening! Heres to nice relaxed racing! Mark

Can somebody clarrify this: To propose Lipo for the next AGM, do we need to propose the full ruling in detail? or just a "I propose we run Lipo to EC regs alongside SubC"

I say take the majority of rules already setup from the super-stock tourers, (who I think are using them this year). I think it states that they must be no thicker than the equivalent SubC Cell, and be of 2s1p formation (i.e. 7.4v).
There maybe more, but I haven't checked. M

I hear what your saying Mark, and I presumed the same - but I want to know for certain so it can be done right.... can somebody confirm?

the tc lads proposed lipo be allowed and the eb take control on spec's , though you could ask the lipo saddle spec be allowed a higher height as most higher capacity saddles are taller due the the cells in them
if you restrict height to tc rules you restrict capacity to about 3200, you need around 30mm to get up to 4800 ish

I think that the electric TC bys have a capacity limit of 5000mAh but to be honest, I think that 3200mAh will be plenty in off-road, even for modified racing.
Although I have not had first hand experience, I have heard that the efficiency of LiPo cells results in a 3200mAh pack being more comparable to a larger capacity NiMH pack.

Chris, i think what will need doing will be looking at all the rules that currently defing the use of Sub C's, then propose amendments to that (or those) rules and see how it goes.

Should the pack change 'expand' slightly when fully charged, as mine has??? This was charged on a robitronic overloader, and has got very slightly warm to the touch.
Hope it hasnt fried...

I charged at 3.0A, on Li-Po Mode with it on CC/CV charge mode.
You cannot change this...

Hmm..interesting.
My micro LiPo's have never gone over 8.4V..I think the EB have even set a limit of 4.2Vpc?? Id keep badgering Trak Power mate...better to be safe and not blow my face off tonight at Hereford
