That’s ridiculous. First off how would anyone determine an alternative charger was used? Secondly a Satiator is more advanced than OEM chargers and there’s no risk involved.
Satiator Charger with Specialized?

I wonder how Satiator handles the SL main battery with Range Extender at the same time.
And how increased charging current affects the battery longevity.
Satiator seems to belong to the world of people who determine the battery charge with a voltmeter....
P.S. Tom: What diagnostic information information can you extract from a typical battery you're using?

I am not sure about that. yes you can adjust it for all kinds of batteries and control it more. but it cant work with the BMS to check battery temp and if it is balanced and such.

@tomjasz: It looks you are trying to avoid answering.
Here is the information for Specialized SL main battery and optional SL Range Extender that can be extracted from the e-bike:
Does Satiator work at this level with Specialized batteries? Can it charge the SL batteries in Y layout? Does the Satiator know you shall charge and balance both batteries at the rate proper for the smaller Range Extender? And finally, why use the Satiator in the first place? To shorten the lifetime of Specialized batteries with excessive current?
You better e-mail Specialized to ask how your potential warranty claim would be handled. What is wrong with your existing 4A charger, Hammick? And are you aware the new batteries are very expensive?
Have you thought about reasons? We, Specialized Turbo owners belong to another league of e-bikers. We, for one, do not need a voltmeter to determine actual battery charge

Relax man. I'm interested in the Satiator so I can charge our ebike batteries to 60% or 70% and have the charger shut off. I will also use it on my EGO mower and blower batteries for the same reason that I don't want to take them to 100%. I don't plan to charge at high current. In fact I will probably charge overnight at 1 amp. I don't have a range extender but if I did I'd have not problem charging it with the Satiator.@tomjasz: It looks you are trying to avoid answering.

I know quite a bit about charging lithium batteries. We have an off grid home with a 48v solar system with LifePO4 batteries. I built that battery system myself with Lischen 280ah cells and a highly configurable BMS with remote configuration/monitoring capability.
So we get it. You are content with the stock charger. That's great. I have two of them myself. One is charging my bike right now and I'll be back and forth to the garage several times so I don't go above 60%. On my Levo Comp that means disconnecting the charging and turning on the bike. It's easier on my wife's Tero since the display shows the charging percentage.
If you don't have anything constructive to add please move along.

Hammick, take no offence. A simple time switch would get you at the same without the extra cost and any risk.
Honestly: what does Grin know about the intricacies of Specialized BMS?
The constructive remark: The 604 Wh Specialized battery costs US$1,200. It is not my money, see?

Dont be one of those guys
(A whole nuther league)Thanks for the pic, possibly a new avatar down the road
I have one of the grin adapters and have used it to charge my two Brose bikes (iZIP moda and Bulls Evo 3 eMTB) with my satiator. No need other than I wanted to and wanted to see how much charge I was putting in the battery (which can be derived with a wattmeter plugged into the wall socket but then you have to account for charger efficiencies). Brose chargers are also super expensive ($200+). I bought a rosenberger breakout cable setup from Luna awhile back and used a logic analyzer to verify there was no data transmission over the data lines with my Bulls ebike while plugged into the charger. FWIW, there is definately data transmission over the data lines between the battery and motor (should not be relevant to this discussion)
Most of the statistics Stefan is bragging about can be derived strictly from the battery side. Stefan is also talking about the SL version which could be different from the OP.
Chargers are much simpler than Stefan implies. Using voltage to determine battery SOC is pretty common/standard in the industry. You can also measure temps/pressure but that seems to be done more on the battery side unless your talking super high end stuff (non ebike). In the end, ebike chargers typically simply supply power and the BMS works it out. This is not always the case (RC hobby) where the chargers can get very sophisticated(I own several)
Perhaps specialized is different, who knows...Im not in that league
Perhaps Stefan can provide CANBus datalogs to get to the bottom of this issue so us e-bikers could all benefit

I have found an interesting thread:
Charging to 80% without a Satiator
And then I could find several posts of you, @tomjasz there, for instance:
I do agree you are playing in the Voltmeter League
Here, the "S" does not stand for Satiator, though
I have never seen any Specialized technician using a voltmeter. Instead, they use some diagnostic software, and the tool is connected to the battery by a proper plug.
As I said, Hammick can use a simple time switch and learn very quickly how long it takes to charge his battery to 60-70%. Switching the charger off and turning e-bike on will give precise battery % on the display. (Interestingly, SL e-bikes -- not the case of Hammick -- can be charged with the system on, and that shows the battery status all the time).

Ridiculous argument!
You’re cherry picking posts. My eBikes.ca CA3 and Satiator are just as capable. If you took the time to look at the programming files we’d not be subjected to supercilious responses. Come on Mike! You post like you found Heysus.

Lets all ignore the (never-ending) arrogance on display here and shift to a simpler approach. There's a way to do limited charging (80% etc.) that is much simpler and uses the unfortunately restricted Specialized hardware.
Spend $9.99 and use a cutoff timer.
Learn the charge rate per hour and set the timer accordingly. You want to use a rate-per-hour so you can work your way forward from any starting voltage.
A timer like this also serves as a safety cutoff to cut power to the unit.

I wonder Tom if you risked connecting a non-compatible charger to your expensive Specialized e-bike. In the worst case, it would be your money and fire risk

Especially the ignore part, I have found that feature useful on here the last few years....
I'm not following you. That information has absolutely nothing to do with the Specialized charger. If you charged your bike with the Satiator you would have access to the exact same information. I assume you have access to the Specialized dealer software. Mission Control shows battery health and charge cycle count.
Do you understand how a CC/CV charger works?
I was juggling numerous things today when I hooked my Specialized charger to my Levo and forgot to set a timer for 45 minutes. I started at 60% SOC and only wanted to charge to 80%. By the time I remembered I was at 93% SOC. That would not have happened if I had a Satiator set to charge to 80%
I may just end up using a smart plug with timer capabilities but there is absolutely nothing wrong with using a different charger assuming it is the proper voltage/amperage.
