You can’t get a 504w battery anywhere at the moment so getting hold of a 630w may be a bit of a challenge or maybe that is why you can’t get a 504w as they are working on the delivery of the 630w ones ?
So 2019 models may have a 630 battery... interesting
I was told that specialised wont be changing the chassis / frame this year as it's not due a frame refresh until 2020.
So from what I was told (and rumours) Here is what I suspect it could be:
Released / announced the last week in July and shipped and received by Riders and stores 1st week in August (this date actually came from Specialized directly)
New Battery throughout the range 630wh for comp and up.
Same Style Frame.
All Carbon frames will be fact 11 carbon through the range (no fact 9 etc) therefore lighter.
Same motor (brose) optimised for use with new battery and lighter frames.
Different shocks/forks etc
Possibly 9 speed options or EX1 shifters / cassette optimised.
Small price reduction from the offset, due to the larger amounts of bikes expected to be ordered.
I think that's reasonable, and I would be surprised if there were any more changes, but if there are, I'll wait it out as as I'm not buying mail order again XD
I’d love to see an increase in battery. But I can’t work out how they can cram in more cells into the existing battery design without making it bigger. Unless the remove some the controller / LED cluster and internal boards to accommodate the extra cells.
I believe they use 40 x 18650 batteries for the Levo/Kenevo battery unit. Please feel free to correct me if I am wrong on the following as I am doing this from memory. The 18650 batteries are 18mm wide by 65mm high.These batteries range from 2.5Ah to 3.5Ah. Not sure what value Ah battery they used to create the 460wh and 504wh battery but it would be somewhere in the above stated range.
Have a look at the attached screen shot of the Levo battery. There appears to be quite a big gap between the batteries so in theory they could, with a bit of jiggery pokery use the slightly larger and higher output batteries that have been released ...... either the 21700 21mm x 70mm or the 22650 22mm x 65mm. These put out around 3.8Ah to 4.5Ah.
So if they could squeeze 40 x 4.5Ah batteries in I believe this would give you your 630wh battery?
Assuming the use of 18650s, most packs are 10s4p (10 cells in series to get 36v, 4 sets of 10cells in parallel to get the capacity). I suspect the 630Wh battery is 10s5p of 3500mAh 18650 cells rather than a different size cell.
It would be very simple for Bosch 5000Wh Powerpack owners to use a battery that's 25% bigger in one dimension, not so sure Levos have the same leeway.
Do any premium battery manufacturers make the bigger cell with high "C" ratings? I'd be very reluctant to sit on bike full of Trust(me, we will catch)Fire batteries...
Looking at the screenshot of the battery it looks like it may be possible to squeeze in another 10 x 18650 batteries into the same space by moving all the existing batteries closer together.... well I guess we will find out when it gets released ?
I’d like to see the battery pack snap in half. Make it modular, where you can run one small pack and one dummy pack. Or 2 small packs to make one normal pack. And then you can keep a small pack in your backpack, and 2 small packs on the bike. Which would be equal to 1 and a half packs to extend your range.
You could also run a small pack and a dummy pack and the whole thing would be lighter. For those times you only want to bash out 10-15km.
Really interesting info in the article ? I jumped on to the BMZ website and they have a number of cells available including the 18650 and 21700. The highest output is a 5Ah 21700 so this is looking good for very high capacity ebike battery. It also looks like they are developing an ebike motor which looks very very similar to a Brose.
