Also, here's a handful of more options. If you have a 15s 5ah battery, you might want to consider the 14s 2a charger: https://www.aliexpress.com/store/group/14S-to-16S-Li-ion-charger/2344164_510899706.html?spm=2114.12010608.0.0.3a1a5cc0dEwXW8 I have two of their (SZXJR) 24s 9a chargers, and been usi...

Well I've been trying to figure out what way I want to go with the battery. I can do two 20s6p packs or a single 20s12p pack. The idea with doing 2 packs is I could shed weight when I didn't need the high capacity and I could shorten my charge time by being able to have both packs charging at the s...

Yes, braking power is very good! It'll launch you forward pretty good with regen maxed out. You'd never expect braking force over time to be a source of hand pain, if your grip and glove game is lacking. As far as handling, it gets very stable at 25, and cruises in a straight line very well. This fr...

Thanks! I knew how I wanted to ride it, and did my homework figuring out the number, type of cells and configuration I needed. I think I can get 180 miles on a charge cruising at 20 mph, which only asks for 3 amps from the pack (27 ah usable). The volts are doing all the work, which is part of the e...

I also ended up going with a WCEC 6T edge 1500w motor, since the ~7.7 Kv was far more appropriate for my 24s voltage. I also use regen on the rear, since I haven't had the caliper mount attached yet. Braking power is very effective from 35-0 mph, when combined with that awesome 4 piston saint calipe...

I have an issue installing python 2.7.1 on a new mac with windows 8 bootcamp. The installer quits prematurely, citing some error that I will update later with a screencap. Python 3.7.0 will install fine, but won't recognize the older files for XPD. So I'm stuck! Anyone have or troubleshot this issue...

Wcec seems to have something similar to the edge. That's the place to get it for now. I have the 6T (~7.7kv) edge 1500w , running 24s on a 26" MTX39 rim. I'll hit it with 45 amps (4000w) on a WCEC 18fet (for 15-20 sec), and she'll do every bit of +52mph. Trying to ease into the throttle, pulling 25...

Well, now I'm thinking it's the controller that got damaged from a few too many volts. Everything is working fine, CA included (fairly certain). Good thing I have an 18fet lying around to slap on it, and upgrade while I'm at it, lol. Gonna need hubsinks and statorade for this baddie...

Out riding today, and the voltmeter goes haywire, all over the place, dipping down to 70, 50, 15v , when it was just at 90v. It (the CA) wouldn't power on a few times, then when it did, the voltmeter was 4v off, and it sagged by twice as much as it was supposed to. Using regen, the volts went up to ...

No, I know what you meant :) . I assumed you were right, since none of the senior members were correcting you on it. That's always a good litmus test, lol :) But, you know how it goes ... it's nice to find third party confirmation on a technical thing. Plus, it's good to know that I'm treating the c...

Okay, so for what it's worth, someone did actually post the max charge current for a GA cell. It's 3.35a , found here in thunderheart's reviews. I have the Sanyo GA , which also tested over capacity at 3550mah. So, I have no worries now if I slam 18a into the battery.

If you NEED to you can. But charging so fast will kill the pack in 100~200 cycles at best. These are the things I want to know about. I'll only be charging at most 0.3C to 0.4C , which sounds reasonable according to previous replies. I will never (and won't be able to) use 0.5C on this pack. Plus, ...

Oh, wow, so even 1800w is doable on 11p? The battery is sealed away in an aluminum box (hard to access), and all of my other GA cells from the order have been used. But it would be good to test one of them, to see what the thermal max is for charging. So, if I can use this much power, what is the sa...

As stated in the specs , a GA cell has a standard charge current of 1.675a (others say 1.475a) . Is this 'standard current' a safe value that avoids too much heat? Or, is there an unlisted fast charge current for the GA, as is listed for the 30Q (1.5a std, 4a fast) I have a 24s11p of GA that I'd lik...

In my area, most shops do and have been turning down any motorized bike. But, times are changing, and some of these shops have intelligent, forward-thinking employees, who do see a real future in them. All gas bikes are currently turned down, because of the Florida Man that typically comes with them...

If yours won't work without seeing the battery, you could charge the battery it was meant for, then use that battery to run the boost converter. (even leaving the charger connected to the battery so it keeps running without discharging the battery too far). That would enable you to use a higher cur...

All right, I don't see how this wouldn't work, but may as well pass it by you guys as a sanity check. I have one of the affected Cycle Satiator 72v chargers that needs to go back for warranty. So, in the mean time, I still want to ride my ebike with a 24s battery. I have a 58.8v 3a charger, and I ma...

Please download the CA3 Un official Guide and take a look at "Appendix A. Calibrating the Cycle Analyst RShunt Value" . There are several means there of calibrating your CA to the controller shunt. This is written for the CA3 but is equally applicable to the CA2. Here you can plug your Satiator val...

If my CA 2.4 plugs into the controller (powervelocity 12fet 100v) , what shunt value should it be?

It could be that the shunt value is wrong in the CA, I'm inclined to believe that the charger is correct. You could connect a Wattmeter to the AC side of the charger. Also you could monitor for how long it is charging with Constant Current, and multiply the hours times the Charging Current, to get ...

My cycleanalyst says that I've used 26 ah during a ride, while my satiator only says 16 ah after charging. What gives here? I'm inclined to believe my analyst, but both are from the same manufacturer. This is charging to 97v , and discharging to 87v , which consistently shows around 26 ah and 2400 wh.

Yeah, SBP has good stuff. I use both their HD motor 14T fw, and the $120 UHD crank fw. These mounts feel pretty solid. I can't move it around that much when pulling on it with my hands. So, I think it'll do well at the 2500w future power level. I do want to replace the black zip tie with another ste...

In case you didn't know, Raleigh actually makes cool bikes. But, you probably won't see them in a bike shop that uses them as a secondary brand. Or, they'd likely be selling these out from under the specialized/trek/giant/ etc that they carry. This is a 2018 Raleigh Redux 1 in matte blue , large fra...

Dude, these look great. Exactly what I'm looking for. I'll be considering these for a few upcoming builds.
