I was in Japan a week ago and I got to use that 3600 and it was on fire lots
of power, but I don't think it is going
to be Roar legal in the USA.

Let's hope they are a TRUE 3600mah cell unlike the try sanyo had with the 3300.
Sanyo needs to step it up on voltage and lowering the IR.
Plus remeber.The BIG T has rights to these.
You guys are SPOILED by GP prices.
These packs WONT be cheap.
We will see

GP can and will react to this quite quickly I think. The current GP cells exceed the 3300 Mah rating now (high volt high runtime cells). So GP could simply rebadge its HV line of cells as 3500/3600 without any changes. But-they need some competition!!! Trust me on that one!! I know!!

Default GP cells

GP cells have big quality problems outside of the 4 and 6 cell packs. The cells self discharge at different rates.

All cells discharge at different rates. What are the quality problems you are referring to?

Default Cell voltage retention

If you take 20 cells, they self discharge at different rates sitting on the shelf. If steps are not taken to even these out, you will get cell reversal very quickly.

Car racers won't see these problems using single cell treys and such.

Steve Hill from Hilltop.Your saying GP has quality problems?I have to ask what cells your going to start selling next.
GP has the best quality cells I have seen in a long time on My matchers compared to Panasonic and Sanyo.Ever with the Discharge characteristics.
So can you please share with us your info because Im not seeing it nor is Fukuyama,Kinetix,SMC,Promatch and others.

Default What I am saying......

They are not the best of our applications...we build 20, 30 and even 40 cell packs.

Yes, we have matchers also and you right...for car racers they are good because car racers discharge cells on treys ect.

If you build a 20 cell pack and discharge it half way let's say and sit it on the shelf for 2 weeks. Some of the cells within this pack will self discharge at different rates than others. The next time you charge the pack at high rate, the pack will peak before all the cells within this pack are fully charged. This imballance will grow until the pack is slow charged at 330 mah for several hours.

Also, if you check voltage on new cells you find that some are as low as .9V in the case while others are 1.2V. Matchers will not notice this, they run every cell and balance them out. So in order for us to build large packs we must cycle every cell first. GP also has a serious problem of picking through cells and selecting them for certian customers.

Sanyo cells like the CP2400 and HRSC 2600 all come in at the same voltage. I look forward to Sanyo offering another option.

You are measuring quality in one aspect....all out high voltage during discharge. I am looking at more than just this one measurment of quality.

"They are not the best of our applications...we build 20, 30 and even 40 cell packs."

Then what is this thread even doing in an Electric On-Road forum? Anyone have anything relevant to say about the 3600's in an Electric On-Road respect?
