2023 Satiator Update: New Adapters with Firmware for EUC's, Scooters, and EBoards!

[@HighVoltageKits]

Sweet. Love my Satiator

[@orthodium]

Too bad there isn't a higher wattage model of this charger available, unless of course if you use two chargers in parallel? Would that interfere with the charging stats on each unit?

[@GrinTechnologies]

It's definitely possible to run two units in parallel if you have the wiring chops to parallel connect their outputs. The charge stats would get split roughly equally between each charger but that's not much of an issue.

[@orthodium]

@@GrinTechnologies I already have two charging ports which are wired in parallel, but it’s good to know there is no issue running two at once. I just heard there are sometimes issues with parallel bms wiring due to the possibility of some conflict, but I guess this issue doesn’t concern the chargers.

[@IcyMidnight]

Ooo! For EUCs with two charge ports, can you just hook up two satiators for 720W? 😲

[@jeffreytong]

Nice to see this focus on EUCs. Is it limited to 103V? Would be nice to see higher voltage support for future proofing.

[@GrinTechnologies]

103V is indeed the max. It's scary to think that PEV builders are using packs of this voltage already since it presents an electrocution risk that is non negligible. 72V stings pretty bad with wet hands, and 100V is downright uncomfortable. Not sure why future PEVs would consider going even higher! There certainly isn't any performance advantage, as mosfets rated at more than 100V have much higher ON resistance and you usually end up with worse controller efficiencies.

[@georose33]

I've had mine for a couple years. Love it.

[@jeremyplatt]

Wow, awesome stuff, well done!

[@raylivengood8040]

My 72v satiator has been great ! The ability to set voltage charge limits is probably one of my favorite features. I appreciate the polarity safety alert as well. Because plugs for chargers are not universal on all PEV’s & can be difficult if not impossible to source, I cut at about 30cm above the charger port plug and install a universal connector so I may use my satiator. I trust the satiator safety features a lot more than any charge brick I’ve received from actual PEV manufacturer’s.

[@houseofjob]

How about a new 32S version? Love my cycle satiator, been charging my EUCs via my own plugs for years now, but 72V can’t charge today’s EUCs that are above 100V 😓

[@fitzanator436]

Great work guys 💪

[@jamesemery1]

only thing stopping me buying one is the 5 amp limit on the 72v version it would take 8 hours to charge my pack from flat to full

[@SouthSideChiTown]

Unless it's your main source of transportation, charging above 5 amps will cook the capacitance medium in your batteries severely shortening their lifespan and potentially creating weak or dead cells and risk of fire.

[@jamesemery1]

my cells at 0.5c charge rate is 10amps I know what i'm doing thank you@@SouthSideChiTown

[@nobrakes7247]

Got two love them

[@manp1039]

can you talk more about the signal that the battery or the cycle satiator put out to indicate that a charger is connected to the battery and allows the battery to begin chargin?

[@GrinTechnologies]

Any voltage over 6V will do the trick!

[@IcyMidnight]

Since the adapter is seem to have a comms cable in them, have you ever considered putting an ID chip in the adapters that automatically selects a profile?

[@GrinTechnologies]

Yup and in fact we even have a firmware that supports this, but in spite of it being available no one has actually done much with it. Keep in mind that there are multiple voltage setups that use the exact same adatper cable and plug type, so while there are some contrived scenarios in which this is useful, there isn't much of a general case for it.

[@IcyMidnight]

@@GrinTechnologies I was thinking more along the lines of each cable has a random id, and you can set the satiator to pick a profile from the cable so when I connect my cable id abc123, the satiator selects the 100.8V charge profile for my EUC and when I plug in my cable id 773def, the satiator selects the 50.4V profile for my ebike. I'm just thinking it'd be good to help prevent me accidentally throwing 100V at my 50V pack 😝

[@phototristan]

Which of your new adapters is the one I need for a ninebot max G30LP scooter? The G 30 model has the charger built-in but the G30LP model uses an external charger which I believe I can use the cycle satiator with.

[@calvintanner7897]

What connector is used to charge the 48V batteries with 2.0 amp charger?

[@Warekiwi]

My Satiator has worked perfectly over 5 years charging the 48v custom made battery on my velomobile . I particularly like the ability to set the desired soc at end of session and similarly to my Tesla only charge above 80% unless 100% is actually needed. I would love to be able to do the same with my eMTB (Shimano setup) have you figured a way to connect to Shimano batteries??

[@GrinTechnologies]

It's on the agenda. From what we've heard the communication protocol shimano uses is not that complicated to reverse engineer and it looks like EU will be passing regulations requiring all ebike battery manufacturers to make any ebike battery communication protocol disclosed to allow 3rd party charger compatibility. Nice to hear you've been enjoying it all the same and hopefully we'll have an adapter for your Shimano bike at some point.

[@Richard-y4e1d]

Is it possible to allow the charging of a lower volt than 12v on the lithium charge. It would be handy if it could charge single cell 4.2v parallel packs. Especially for custom batteries.

[@GrinTechnologies]

Unfortunately that is too low for the resonant converter topology used in this charger.

[@Richard-y4e1d]

@GrinTechnologies shame, it would have been nice to update my satiator and send my hobby charger to the bin.

[@HUJUism]

What would be the setting for a 51.2 LFP battery on this model for full charge and 80%. Thank you.

[@GrinTechnologies]

There is no need or point in trying to partially charge LiFePO4 batteries. Just charge to 100%.

[@joeKisonue]

So do i have to program the options in orvthey are preset? I have the Unagi 500. Im about to rebuild my battery and add 16 extra cells to boost capacity. Id like to protect my 40 cell investment by utilizing the 80% charge. Also i know i will have to cut off and solder the scooters charge plug to a 2/3 pin pigtail to match one of the options on that cable kit.

[@GrinTechnologies]

There are both preloaded profiles and you can very easily make any custom profiles if a preloaded one isn't suitable.

[@oldspiced]

are those 5 pin euc charger ports still just + and - ?? (two wires?)

[@GrinTechnologies]

Yes, by and large

[@IcyMidnight]

Did this do 5A all the way up to 100.8V or do they still taper off after 72V? Edit: 360W, so I guess ~3.5A at 101V. Slow by modern EUC standards, unfortunately. 😔

[@zuluwars2996]

I love my satiator it charges a number of my ebike batteries but I'd love to be able to charge my shimano steps battery but no adapter cable is available. Will Grin ever make one for the shimano steps batteries or is it just not possible?

[@GrinTechnologies]

It's just not possible. Shimano has gone not just with a proprietary connector but also a fully proprietary communication protocol between the charger and the battery on the extra signal lines. As soon as the battery no longer sees an official shimano charger 'talking' to it on the signal wires, then it blocks the charge port from allowing current flow. You could in principle do it by opening up the casing and soldering in your own charge leads directly to the V+ And V- cell terminals, but there are risks with that.

[@qqnqqpart]

Best collab video ever! I was on the website a few days ago, is the XLR to Lenovo possible, this is for KingSong wheels

[@GrinTechnologies]

Ah that one didn't quite make the cut when we were choosing which to go with for mass production, but if enough people keep asking then we can justify a run with Lenovo plugs too!

[@qqnqqpart]

@@GrinTechnologies according to the euc world world's top wheels of 2022 list, 5 of the top ten owned wheels in 2022 were KingSongs representing a whopping 34.82 percent of their user base; just Google it, KZbin is weird with links hence not sharing it directly

[@hernberferd6725]

can this charge 12v LiFePO4 motorcycle batteries?

[@GrinTechnologies]

Yup, but not at the full wattage of the device, you'll be limited to 8amps

[@jayhom449]

I have a older Solowheel model charger SHC-8100LD. Would this charger work for me.

[@GrinTechnologies]

For sure, as long as you can get the correct adapter to match the charge port plug on your solowheel.

[@eBoard3R]

⚡👀⚡

[@sgsuper1150]

Mine is faulty and grin wont fix it.

[@SneakySteevy]

I own an Onsra Black Carve 3 esk8. Right I charge at 4.5A. Could this charger charge my esk8 at 8A? Here are the battery spec of my esk8, 12S3P 21700-50S Samsung - 648Wh - 15Ah. Thank you

[@GrinTechnologies]

Yes, it would charge it at 8A when the pack is flat, and then it would taper down to more like 7A as the battery charges up and it hits the 360 watt power limit of the charger.

[@SneakySteevy]

@@GrinTechnologies would it reduce the battery life span if I charge at 8A? Right I charge at 4A.

[@jkeyohm9524]

I want one of these for my Master Pro SOOO bad! It sorta boggles my my that these don't come integrated it into the design of the seat so one can just plug the "wheel" into the wall... I'm patiently waiting for technology to catch up with my imagination 😇 Great work Grin, & Eevees!!!🥳

[@anthonyrstrawbridge]

😊👍🏿👍🏽👍🏻

[@dant.6364]

Is this UL approved?

[@GrinTechnologies]

[@baqyt]

I be use Satiator, and want Baserunner, battery and engine

[@Kotofosonline]

Why have one universal device, if you need anyway few of them to charge your staff simultaneously? Then it is cheaper to have simple, dedicated chargers.

[@GrinTechnologies]

No one is saying to throw out your other chargers if you've already got 'em, but it's mighty handy to also have one in the toolkit that can also do everything. :-)
