so a lower top end keeps me a lot more sensible.
Wisdom there my friend.

Well I couldn't resist. Even though I still don't have a chain/rear derailleur mounted, I took the new battery out for a spin tonight as the sun was setting.

CD,

Post a video for us please.

With no pedalling, I was hitting the new battery pack hard, drawing 6.5KW. My Boost mode amps limit is currently 115A which means it was giving me 115A at 56.5V. That's insane! The full charge voltage of this pack is 58.8, but I had not even fully charged it before this ride, so it was sagging less than 2V at 115A!

My Adaptto could be overshooting the amps limit for a moment also, which is entirely possible. I know the CA does this also, so my assumptions above could be wrong, but even if they are...my average battery voltage being 52.1 means each cell was at 3.72V average for a 49.1Wh/km ride which is pretty hard going so that is certainly promising.
Oh and in case your wondering...I did hit 85Kph, but that was with a quick test of OVS 3 set on my Adaptto. The normal max speed with this battery and my 5T Leaf motor is about 65Kph which I'm more than happy with most of the time.

Cheers
Did you reset battery cycles to zero? I was thinking of doing it with a new battery and I don't know if is possible without setting also tot km to zero?

I didn't do that yet actually...still need to.

CD,

I didn't make a video of the battery build (there are plenty out there just like this), but I will try and do another ride video in the next few months.

Well, so much for a ride video in the next few months....I took the bike out for a 60km blast today. :mrgreen:
I managed to use about 75% of the battery as I was going pretty hard. What's great about this pack is that I can go basically as hard as I like and I know I will always be able to get at least about 75km. I checked the pack a bunch of times to see if it was getting hot. It only got barely warm towards the end of my ride after I had been hitting it with repeated 100A bursts for about 10km. So basically the only way I could hurt this pack would be with deliberate abuse. :D

I will try and make the video this coming week hopefully, but in the mean time, enjoy these shot's:

While I was up there I had this hilarious experience. I had just previously scared away a flock of sheep and had stopped and was videoing a huge eagle (no idea what type) and did a bit of a panoramic shot, then right on queue a sheep came out of nowhere as if to say 'Screw you'!

You couldn't make that happen even if you tried. :lol:

Great shots CD, awesome distance on the battery. Will have to come and visit Canberra again sometime and go for an epic ride or 2. Certainly a great "city" for ebiking, so many options mixed throughout the place.
