The Cycle Satiator, universal charger for the enthusiasts

[JackFlorey]

The CV period - if there is one - will be a small fraction of the CC stage.

"If there is one?" It is often longer than the CC stage, especially with higher power chargers. (Which is one reason why going higher in power doesn't always get you significantly shorter charge times.)

[john61ct]

Yes, the higher the initial C-rate at lower SoC range

the lower the SoC% where voltage hits the setpoint

and thus the higher proportion of total charge time spent at CV stage.

With lower C-rates, say 0.1C and below, can just use HVC to terminate charge, "charge to X and stop" aka CC-only profile

to get closer to the (too high) vendor-theoretical max capacity, voltage can be set a little closer to max without undue stress harming longevity.

That really only comes from high voltage setpoint **combined with** letting endAmps go too low.

If I use CV my usual endAmps is 0.05C or maybe 0.02C if the use case really requires highest cap utilization.

Has anyone else had a aesthetics problem with the screen. When its on I dont notice it. Plastic covering from new is off.

My screen looks similar

Same since new years ago.

I recently received mine and it has the same problem. Has anyone had this remedied under warranty?

Mine is brand new out of the box three days ago and has the mark in the screen. It is not something I am worried about.

I ordered the Satiator with two 14S7P hard case batteries from EM3EV. Batteries are expected in a few days. The charger came with ST3 charge lead instead of expected Anderson plugs. Apparently the batteries have changed from the pics on EM3EV website.

I want to be able to charge and discharge these packs in parallel.

ST3 is a bit of a pain. Is there an ST3 splitter cable or am I going to be replacing plugs? I don't really want to do that... I want keep it all original in case there is a problem later.

What is the third wire?

[amberwolf]

On the batteries, you would have to ask EM3EV what they are using hte 3rd wire for.

On the Satiator, the 3rd wire is a multipurpose wire.

When used with the XLR-phono/anderson adapter that comes with the Satiator from Grin (plugged into the XLR on the non-satiator end of the Satiator's included cable), the 3rd wire is a data signal wire used for programming, etc.

When used either directly from the XLR, or with an XLR-other-3-pin-plug adapter that includes that 3rd wire to it's own pin, it can be used as a thermal sensor signal wire for packs like NiCD and NiMH that need those for safe charging shutoff.

When used with satiator firmware that supports it, an OEM can setup the Satiator to detect that it's particular battery is connected and start charging with the correct profile for it, based on IIRC a resistance on that 3rd wire to ground. (this is mentioned either in the Satiator info page or one of the blog page posts about the satiator, and also somewhere here on the forum, probably within this thread).


Regarding the ST3 splitter, you'd probably have to make your own, or contact EM3EV or Grin Tech to see if they can make you one. (or some other place that may sell ST3 connectors and cables).

Thanks.

Somehow I didn't have topic reply notifications for this thread...

Batteries arrived today. I was trying to gather up everything I needed all at once and it turns out the battery charge lead is its own thing that plugs into the side of the case... I can cut one of those up without any problems.

The EM3EV dongle has ST3 to Anderson so it also looks like the third pin in the ST3 plug is not used.

Hi there,
is there a way we can see the Charge Graph from the Satiator on a connected PC?
It would be very interesting in this scenario where I am trying to see the relationship between the amount of charged Wh and my battery SoC.
thanks for your help!

[Cephalotus]

Hello,
I would like it very much if the Cycle Satiator could also evaluate a "temperature signal" (10k NTC) from a lithium-ion battery in the future.
On the one hand, I would find such a temperature display interesting, but it is also a safety feature to be able to reduce the charging currents at very high but also very cold temperatures.

Why would a Satiator lose all programming after working for several months flawlessly?
GC360-7205

[beeps70]

Mine did that a few months ago. Told Grin about it and they did a exchange.No real reason given why it happened.
