I love the Satiator. I have two rates of charge programmed in right now for my "48V" lithium ion pack, 4 and 8A. I nearly always use 4A, and that's what you see the results of on the screen. I like how intelligent it is. If you leave it connected for some time after "charge complete", if you have a good BMS in your pack, you'll find the BMS will go into a cell leveling mode - at least, mine will. A minute or two after "charge complete" and the rate is zero, the BMS will ask for a little power to top up individual cells and the Satiator reflects this, telling you that its' now adding a little, what the rate is and what the new total is - its like auto-restarting the charging except that it knows the battery is the same one so it adds to the pre-existing statistics. The first few times I charged my brand new battery pack, the time this took was considerable. But as time has gone on, the balancing effort takes a lot less time - at least, that's my perception.aja wrote:How happy are you with the Satiator? The charger that came with my battery makes a whirring noise (fan, clearly). Tempted by the Satiator but it's almost the cost of the motor, given I'd have to import it and pay taxes. Looks neat though, especially as it's quiet, adjustable, extends battery life, allows faster charges and shows the Ah used.RTIII wrote:Here's the charger following the top-up after the trip:
So, that's 0.49 amp hours per mile, or, 2.05 amp hours per mile! Not bad, methinks! Now, it's true, back in June when I was in good shape (before I injured my leg), riding my Legran (with TSDZ2 48V 15A), I could get a lot more than THREE TIMES that, not much short of four times, I still consider this an awesome feat. With the Legran, I think my theoretical maximum range is around 95 miles, give or take a few, and the theoretical here is only around 26.
My only complaint of it is that they use this very well made, well designed, but VERY heavy intermediate jack (male / female pair) in order for the unit to accept alternative leads to different kinds of battery terminals. (Looks to me it's the exact same jack as is used for microphones in the USA - and other "professional" music connections for a sound stage.) I think they offer 4 kinds of what I would call a pig-tail (that goes from the intermediate jack to the battery) and you can also, of course, make your own. The problem is that they put this intermediate jack way out on the end of a fairly long lead so that the adapter lead you then connect to it is fairly short - WRONG WAY AROUND, if you ask me! FAR smarter would be to have that heavy adapter on a shorter lead and have the final pig tail be as light as possible and as long as needed. For me, it matters because the final connector into my battery isn't nearly as robust and hanging weight off it is a stupid idea. So, I have to somehow or other deal with supporting that weight other than just using the connector at the battery. But, I've gotten used to it.
Now that I think of it, smarter still would be either use a much lighter jack OR skip the damned intermediate jack entirely. I don't need the jack and I'd be just fine having two or more cables going all the way to the charger when I want to switch what connections I'm using. I guess they figure this way is faster and people want faster. -shrug-
