Finished building my 25mph Ebike

If I remember correctly, Castle did have batteries at one point. Dunno what happend with that one. A123racing/Enerland is out of the hobby market. Not enough sales to justify that market sector. Acepow had a good chemistry, untill the bossman screwed up. So all that there is left is Hyperion as a quality pack. And how many people will really spend big money on a battery pack, when they can get the same capacity for 50% less. Not many, I'm guilty of that one myself. So in my eyes, it will be a gamble for Castle to make any money in the current USA market.

My 4s Acepow packs have a cell resistance of 0.9 mOhm on average when charged at 30A. At 40A charge rate the resistance doesn't register for a 1p config. That is not bad at all for a 67 dollar pack, considering the A123's are at 8 mOhm. Difference is that the A123 can put out some serious amount of Amperage in an instant. More then my logger can record. But you can see the difference in RC's. My GTP for example has faster launch on 4s2p A123, compared to the 4s1p 5000mah Acepow. The Acepow will have a greater topspeed, but in a dragrace it's too late.

All good points Snell, but remember CC has a factory in China already, which would make it fairly easy for them to start fabbing up Lipo packs and shipping them stateside or wherever to make some money. With manufacturing in China they should be able to keep overhead down and make a reasonable profit, and at the same time provide a competitive price for the hobby. So I think it would be a win-win for CC and for us.

I have not had a whole lot of experience with anything but the nickle/metal batteries. I have a couple of Lipo packs but have not even gotten to use them because of our move. Plus I have not wanted to invest a ton of money into Lipos while waiting for the prices to drop to reasonable levels. Lets be real here making Lipos is not any harder than making alkaline batteries. SO charging these rediculous rates just because they are the newest technology on the block has to run thin at some point. Personally I don't see why Lipos should be any more expensive than Nicads or Nimtl batteries. It just doesn't make sense to me. Even something like those Primatic cells at $51 a cell is pretty greedy if you ask me. $25-$30 would have been plenty, but anything with a new design seems to get jacked up just because it is somewhat unique until the chinese knock offs start coming out. I don't even see how Maxamps stays in business with their outragious prices. Anyway all good info. Thanks.
