well...
have you TRIED these cells? Or just read the "review" given by the only distributor of these??? Do you know that there is some 4600mAh Sub-C cells out there????They are branded Venom... and they suck. Now higher is NOT always better. The 4300mAh from GP are not as good as the 4200mAh from Intellect... Try thing, then tell me that it is better. Right now I don't think you actually tried a lot of things, since you argued that MOSFETs are not good.... |

im using two Intellect 8.4v 1400 mah for my SIG, running with an m120 spring and a few internal upgrades.
for a trigger happy guy like me, it lasts me about 5 hours and this is in a cqb scenario. on the open field, where i place shots less frequently, it lasts longer.

that sanyo sounds like a nicd and the intellects are nimh. Nimh batteries do not require discharging and they are not subject to a memory. although, they have twice the capacity they performance gradually decrease in game until they run out while nicd will pump full power until thats it. I like large nicd personally but just make sure you don't cook'em.

Sanyo makes some Ni-Mh batteries too.
And usually, it is the opposite, Ni-Cd decrease slowly when Ni-Mh will die maybe in under 2 rounds... It is that extreme. Probably the ones you have tried (if you have tries some) where not charged well. Most people don't use the correct charger or use a very cheap charger... this really damage the packs and cause it to perform really bad. |

I did a little research too.
These cells are actually re-wrapped 1400's. They might also have been conditionned. Not sure yet about that. But since they get better specs, chances are that yes. If you REALLY want a kick ass pack, just get some Intellect cells from SMC. They are a bit pricey, but you can run a 7.2v pack just like a 8.4 one. Worth the little investment if you have the proper equipment to maintain them. (ie: a discharging tray, good charger and a cell balancer) *edit* Just came to think about it... last year, there was not any one who used intellect because they where new cells. I will see in 6 months, if they are a lot more avalable, I wil test them. Last thing, they probably are just like the other unknown brand I have tried. They outperform anything when they are new, but are dead after only 70-80 charges. Last edited by Kos-Mos; March 26th, 2007 at 23:42.. |

funny that changing the wrapping on the celles make them 0,51 mm longer and 0,25 mm wider and 0,28 grams lighter. you just want to be an ass dont you, even when an electrical engineer have testet them and proven them to be better you still argue.

I love watching people argue about battery brands when in reality, they chemistry is 98% the same. Battery chemistry hasn't changed in 100 years and the advances we've made are minor - not enough to cover the vast claims made by manufacturers.
Buying a battery based on the connectors and wires (silicon) makes sense to me. |

So my cheap tenergy batteries that after one season (maybe 50 cycles) that drops 400mAh in its overall capacity is just as good as my intellect batteries that after the same amount of use still holds 100% of what it did when it was new? Yes I know the chemistry is 98% the same but there is a HUGE difference made by quality.

Yes and no.
As I stated previous, build quality regarding things like connectors, housings, wires, or even the construction of the cells themselves can be a deciding factor - and most people know what the premium brands are (Sanyo for instance). What I am referring to is when battery manufacturers themselves make claims beyond that regarding battery technology itself and how their brand is superior, leaving the consumer with the impression that their battery is somehow chemically and therefore electrolytically superior to another which simply isn't true. |

Ah, okay, yeah I only pay that little more for Intellect cells because you get more cycles out of them.

you might want to try buying a Cheap 2/3 A NiMh cell and match it against a IB 1400 or an Elite 1500. there is an extremely large difference. espeically if you use it for high drain applications. given the difference between IB 1400 and Elite 1500 are not that large but if you want the absolute best for a high performance application you will know what to choose. and seriously it is not something i am just pulling out of my arse i have tried at lot of different brands, since i dont want to pay more than i need to, and batteries is one place i just dont want to go on a compromise. quality is important here, espically if you use them in a single pack and dont couple them. |

What do you think will happend if you ADD a layer of plastic on a cell??? They sure as hell won't shrink down!! And just take a look around other brands, even inside the same brand... for example..take Intellect's 1200's vs their 1400's...how come the 1200's are a little bit lighter?? Here is an even bigger difference. I went to a race recently, and the pratice packs where 2400mAh Ni-Mh packs, branded Team Orion. The finals packs where 3000mAh packs, also branded Team Orion. We had to re-balance the weight around the car and remove some weight because the 3000's where almost 200g heavier. They are the same brand... same chemestry... You can't make a chemical reaction produce MORE energy AND remove some weight at the same time. Only way I could figure is that they used a thinner metal case to fit it and maybe some thinner tabs between the cells. Which if this is the case makes them a lot more susceptible to leaks and failure. As I told in my last post, I will keep an eye on these. They might actually be good. But as you said yourself too, I don't like to buy twice. That is why I stick to some packs that have made their proof. In fact I think I will order 10 packs on 7.2v configuration and send them in a stress test... 10 000 cycles, but not on a charger...in an R/C car. They will be compared to SMC Intellect cells, and matched Team Scream Intellect cells. Both 1400's. If they still outperform, I will be the first one to thank you to have brought this to me. If they do as I think and die after a few cycles, then I will know not to buy them anymore. |

the size is measured from the metal front to the metal back so the plastic wrapping which is not there will not affect the size.

hmm
where you the one who did the mesures. because I don't see anywhere on the page you have posted a cell that have been butchered to mesure it. Just so you know, we mesure the cells WITH the protective cover. it is called "working condition" you can't run the pack without the plastic. And variations in LENGHT occur all the time. 1/2 a milimeter longer is within the fabrication standards for a 2/3AF cell. They can vary of up to 0.80mm if I remember well. It makes no difference in capacity or drain rate. The only possible way to make a pack higher capacity is to densify the internals to squeeze more stuff in there. Doing so will also raise the internal resistance. Looking at the specs only, remove all the wrapings and I would say it is actually some 1400's zapped of some similar conditioning process. Just so you know. As fresh new Intellect 1400mAh pack will hold about 1700-1800mAh. It is always above the rated capacity. A 1400mAh pack that holds only 1400mAh is near the end of it's life. It got no punch and can't last hafl the time it used to. |
