" Good idea. Ya, except with multiple power wall banks. Have to keep them isolated. I'll be contacting you soon about setting up the Sevcon. My battbox is 1/2 done. "

I didn't think so... I'm still trying to learn how to integrate solar panels with different battery packs. I have 4 deep cell Pb acid batts to make one battery bank with, and then the retired Nissan Leaf bank to make another one. I was going to make the Pb acid bank a separate 12 volt system, and keep the Nissan bank a separate high 110 volt system. I'm researching different solar converters/chargers now. I have a lot to learn still on how to tie it all together. Sorry for taking your thread off topic!! "

Richard230 created the thread Alta R5.8 battery pack article.
" The September/October issue of Motorcyclist magazine contains a two-page article, starting on page 32, titled "Alta R5.8 Pack". You get one big photo of the outside of the battery enclosure and 1/3 of a page of text. So you should be able to read the entire article at a magazine stand in about 2 minutes. Or you can buy the magazine for $12. Anyway, the point of the article is to let the reader know that the 2018 Alta battery modules have been upgraded with a unique battery chemistry designed to yield maximum energy release over longer periods at lower temperatures. This new battery pack will allow the Redshift MXR to produce 50 hp and 42 pound-feet of torque, 10 better than the older version, using the identical motor."

The article also states: "The company won't say what's in the mix or exactly what it changed compared to the 2017 pack. Alta claims that information - and even the identity of the manufacturer of those cells - is proprietary." "

" I have had a ton of fun riding my completed project over the past year, but would like to sell it in order to buy a Zero.
I am not interested in parting out as I still use it as my daily commuter bike.

For some reason it is not showing up on the EValbum site, but hopefully it will soon.

Components:
Vehicle-2004 Kawasaki ex500 ninja 500 I bought a salvaged ninja 500 at an auction and removed the ICE, swapping in all electrical components and made it roadworthy by replacing seals, bearings, brakes, and tires.

Motor - Mars ME1003

Controller - Alltrax SR 72400

Drivetrain- Direct drive, 14T front, 55T rear 3.9:1

Batteries - 11 Nissan Leaf 62AH cells in series configuration. Kept slightly under-charged to stay within Alltrax voltage limits and to prolong battery life
System voltage - 90V

Charger - Delta-Q Technologies Delta-Q QuiQ-Icon On-Board 72V Battery Charger

Instrumentation - Cycle-analyst V3, always on rear-view camera

Domino throttle

New headlights as well as old fiberglass fairing with headlight

Top Speed - 70 MPH (112 KPH) I take it on the highway somewhat regularly, but it has limited power for passing at max speed.

Acceleration - Very brisk, about 4-5 seconds 0-60mph. I can out-accelerate every car I've encountered at stop-lights so far.

Range - approximately 50 Miles (80 Kilometers) My daily commute is about 20 miles, so I rarely go further. Range is significantly longer if ridden at speeds that are not fun (20mph)

Tires - Brand new Michellin pilot street radial

Odometer - Frame has 70,000 miles, but all bearings were replaced and structural integrity was meticulously verified. About 3500 EV miles so far.

" Q about dumpcharging one pack from another...

If you have a 100v pack drained down to 72 v, how do you calculate the max voltage of your charging pack? And does there need to be a shunt and fuse between the two packs? "

" Not sure, probably not much different pricing than they have on their site, because of shipping and tariffs.

People have been using them a while. I know a couple people that really like em. So far, it's been balancing cells while I charge. Haven't hooked a disable to it yet.

For solar, I didn't think there was much above 40%... 60% is pretty insane. I bet it's $$$$. "

" How much $ do you think you can sell the BMS for? I would need one for 24 cells. I'll wait until you use this for a while to see how well it holds up to regular use, of coarse.
I was thinking also of dump charging my new pack with my old Nissan Leaf pack wired to solar panels. That was going to be my next big project whenever I can swing the expense of the panels. I'm thinking a 2K watt system would be good, but I think we are on the verge of a major advancement in solar panels. Right now we are at about a 20-24% efficiency. I just read that there was a major discovery of some new test panels that achieved over 60%. Its exponential technology, so the next wave of solar panels should be in the neighborhood of ~50%. That will be game changing and very noticeable. I'm thinking of waiting for this. "
