Were going to check with ROAR and see what can be done for approval as it appears that EP4600s were approved without them ever being submitted.

Default nimh batteries

Sanyo -> GP -> IB -> EP -> EnerG. Each time the cell manufacturer changes, so does the reliability and longevity of the cells, sometimes for the better, mostly for the worse.

I hope that this new cell will be durable and reliable like the GP3300, but we shall see. Otherwise this seems like a last ditch effort at nimh before LIPO.

Good luck.

how about giving some specs out for the cell, like expected IR and cell voltage, so we can have something to woop woop about.

Although I do agree, to an extent, they have come from 'a factory' that probably makes other cells, the question is, has SMC/Promatch stipulated expected performance characteristics from the manufacturer?

What I want, is a reputable company to make a cell like a 4000. Less capacity than 4200 so the capacity for it to be more stable as less energy required, the voltage will still be great at GP3700's and IB3800's were capable of awesome voltage. 4600 is unnecessary, just maxing out the cell which cant be good for reliability. The more capacity you try squezzing out, the less reliable it becomes, is impossible to increase capacity and retain stability.

I'm pretty sure we that a lower capacity cell would be a bit more reliable but I think the majority of the problem comes from the increase in voltage. IB3800s were 1.21 at best now 1.23 is the standard.

Some racers are well educated when it comes to cell capacity but ever since EP released 4600s we have gotten many emails asking when we would have 4600s so the fact it that some still think capacity is relative.


For those looking for numbers we really can't post exact numbers as were waiting for our first shipment that is due in next week. Based from what we have seen sample wise we hope that they will be 440+ with 1.23+

LMAO.... picturing Kropy writing a letter to Santa when he has a hard enough time spelling his own name.

With all the new batteries entering the market, it'll be interesting to see if we racers find the relability that we are looking for. I can say that the current offering of EP4600's seem to be better then the IB4200s that we all struggled with last year. It's nice to be able to charge packs more the three times before worrying about large drops in battery performance.
