Anyone have a Luna cycle ebike charger? They don't sell a 12s version, and I emailed them about it, and they basically told me to go look for a Lipo charger on HK. :?
Anyone know if these can be adjusted like the bmsbattery chargers? I'd rather order from someone in the US if possible, but I don't want to shell out for a Satiator.
 
Chances are there is an adjustable pot inside. Soon as you turn a screw to open the case, bye bye warranty. Don't ask Luna for help after you do that.

Whether it can turn down as far as 12s, I have no idea. It's a 13s charger, so turning it down 4.2v is plausible. If you use the 90% switch position, it will likely under charge a 12s pack, but might be close enough to work.

Somebody has to buy one, and open it, take the pictures and post it here. Tag, your it.
 
I prefer to use my iCharger and leave my Satiator for Li Ion use. That way I can charge and tis with or without a BMS.
Far more features than any 18650 pack charger.

Several of us bought them just not to modify and never opened up. Sorry about the 1010B, I had forgotten.I bought it for 10s packs for my 36v setups.
 
It does have features worth $100 to my way of thinking. I really like my EM3ev charger with three position switch. I use it with an external volt meter all the time. This one has the meter built in. Nice!

My external volt readout only cost 3 bucks, and the Em3ev charger is only $60. But add shipping and it will approach $100.

Compare prices with them, including shipping? If you don't want the three position switch, likely you can find a kingpan type charger on ebay for about 60 bucks, shipped. Like this. http://www.ebay.com/itm/58-8V-3A-alloy-case-li-ion-battery-charger-for-electric-bike-48v-battery-pack-/201279247330?hash=item2edd2d93e2:g:XIgAAOSwYGFU0Hpn
 
Thanks for the reply. I have inquired with the eBay seller about getting a 12s version, so we shall see, but I do wish I was able to buy what I am looking for from someone in the US. It is too bad that Luna doesn't offer a 12s version. I may still just buy one and crack it open to see what is inside. It can't be that much different from what all the Chinese vendors sell. I figured the quality control would be a little better, but maybe not.
 
you can specify the exact voltage you want, when you buy some models of chargers from BMS battery, btw. But these are not the great quality items.

Might have to buy 2 or 3, to get one that works very long. And they'll zing you on the shipping.
 
Yep, I'd like to see EM3ev carry a 1000w charger similar to the one on BMS battery. But that's too big for most people.

I hesitate to send money to BMS battery for sure.

For touring, a charger able to shoot 1500wh into a 2000wh pack in an hour and a half would be nice. Right now I can charge at 500w, using two chargers.
 
Seems like the Lunacycle charger is just a Kingpan charger and they added the components.

You'd do much better I think by buying a charger from EM3ev.com

Like another person said its $60, and it looks like shipping should add about $20. A voltage readout isn't worth the difference. Plus I've heard EM3EV has way better service than Lunacycle which is weird because you'd think an american company would have the better service. Who know. But the EM3EV chargers are known to be very good. A cycle satiator would be nice if I had the money!

Looks like the tins that Seigfired and Roy used to give me with German holiday cookies...sorry, completely off topic..
 
Mean well does not say if the controllers are adjustable for difference voltages ?
the link to mouser show many different models of the Mean well,

Your picture is too out of focus for me to see if that is a screw driver at the lower right of your controller ?
Are those Mean wells adjustable, for Volts, or Amps , or both ?
If voltage adjustable, what range ?

At $ 135 plus shipping , voltage adjust ability , would be needed.

I heard eBikes are bad for the economy, by I don't make decisions on what I heard. Ones a USA supplier, the largest distributor of BBS series, the other sells far less, and can't or won't supply parts. I heard.
 
Mikebergy,

Do you have an accurate multimeter ?

There are Threads here on E.S. that go into detail on what Dogman Dan is saying.

I opened up my Cheep Chinese Charger and saw the Pots, he and others on other threads are talking about.
I have only one working one at this time so I am not ready to play around with it, I will do that later when I get another ,
better quality one , then adjust the generic 48 volt , one that I have .

Yes, I have a good multimeter, but was hoping for something nice without having to open the charger up. Luna basically told me they can't or don't want to offer a charger to me with the charger set to 12s. They suggested a balance charger setup to me (not what I want). A Satiator would be perfect if it were not as expensive as it is - I don't need all the options it has, either.
 
why would a company catering to, and selling chargers for 13s and 14s 18650 chargers bother with a 12s Lipo user. I just don't get the logic behind your complaint. What am I missing?

Maybe you missed my post, or perhaps I didn't describe well what this product does.
The Mean Well is my third 12S Lipo bulk charger, and I am convinced, my last.
It is, in effect, a poor man's Satiator in the way it works and what it can do.
The first thing that is noticed is it's weight, It no lite weight, due, no doubt, to to it's robust construction and the fact that is fully potted. I have not used it as an on board charger yet, but would have no qualms doing so. It is very slim and I'll take on some extra weight if it means the charger is vibration and weather proof(Designed for outdoor installations).
Here are some of it's features;
Auto adj. AC input, 115V or 220V.
95% effcicency
Short circuit/over-current/over-Voltage/over-temp. protection.
Voltage adjustable(42-53V for HLG-320H-48A, 48-59V for HLG-320H-54A)via internal potentiometer reached from the outside though a port(see pic).
Constant Current level(0-6.75A) adjustable via internal potentiometer.

How it works;
First off, unlike some balance chargers, it makes no difference on the order of how it is connected.
I plug in the AC cord first and the mini Voltmeter I added reads the final out-put Voltage(For example, I set it to 48V for an end-of-charge storage Voltage of 4.00V/cell).
Then I plug it into the pack(I never get a spark doing this) and the mini meter reads the pack's state of charge Voltage.
It starts charging immediately and silently and it is fast.
Unlike balance chargers, it does not interupt the charging, to cycle though, to read cell Voltages.
Just a constant 320 Watts(the Satiator does 380W).
As it approachs the end-of-charge value, the Constant Current mode attenuates to current to the shut-down point, at which the current is just a trickle and a soft internal switching relay can be heard.
It is safe to leave it this way, but since we are talking Lipo, the charging process should not be left unattended anyhow. A timer on the AC input could be installed to turn it off completly(reports from other users, report that is only a very small drain when the pack is left connected w/ no AC input).
I may add something to read Volts and current, but so far, I just leave the current adj. to max.
Words cannot describe how nice this unit is to use. It makes my old Thunder 1220 seem like a PInto compared to a Caddy.
Since it is designed for industrial use, it is much better quality that any of the chargers designed for RC use.
It might seem expensive at $135, but w/ a 5 year warrenty, I would say it's a bargin and one of the best Ebike purchases I have made.
 
I have a few Kingpan chargers in the silver/black aluminum cases that have been set for various voltages. There are a few adjustable pots inside the case that can be adjusted. I have read in a few guitar forums of people creating switches to toggle between different voltages and amps just like the two vendors mentioned in this thread.

I think using a dual throw switch and the proper resistors will yield the variances in voltage that can be quickly selected without adjusting a pot. Extending a potentiometer to the outer of the case would also be very convenient for those that need to make fine adjustments.

I haven't had the time to make the above modifications to my charger, but wish to get started on it. Adding an LED voltmeter would be nice, but I feel an inline watt meter would be best to make sure I am putting in the proper amount of electrons that I took out of my battery packs (and not too much more).

Controlling the amps (3 position switch: 2A, 3A, Max) and voltage (3 position switch: 50%, 80%, 100% or potentiometer?) What type of resistors should be used for such modifications?

Why wouldn't you want to sell a unit to someone if it was within your capability? It is not so much a complaint, as it is a disappointment that a US-based company is willing to do less for a potential customer than the few Chinese vendors. Especially if it is simply turning a pot.

I must've missed your post. I always thought meanwells were just adjustable power supplies, not actual CC/CV charger. I may look into those
 
Well, after opening up the Kingpan charger, I see that there is a pot near the LEDs that adjusts voltage from around 50-70V with 20 full cycles. The easy way would simply be to drill a hole right above the pot in the aluminum case and use a long plastic flathead to adjust the voltage to my liking--a bit tedious if you ask me. Remove the pot, and add the necessary resistors to a dual throw, single pole switch and have 3 strings of resistors to choose from with the three position switch like 50% (storage), 90% (daily), and 100% (range anxiety time?). Volt/Ammeters on that auction site seems to range about 3-5$ USD and can be mounted onto the top of the aluminum case via dremeled rectangular opening.

So.. less than $10 of parts (switch, wires, resistors, shrink tubing, and LED voltmeter) + 30 mins of work should yield me a quick and easy method to prolong the duty cycles of my battery packs--substantially! Because the charger is rated as a 14S/6A charger, a rheostat can also be fitted to adjust the electron flow--my packs are 20A so the max current is not as important to me as it's well below my packs' C rating.

Decision time: I learned about digpots and how they can be actuated by an SPI (Arduino). This would make it quite efficient and durable for many adjustments over time. I guess the weakness is that the Kingpan chargers are not very durable from what I gather from other ES member posts. A small LCD display can even hold presets and simple plotting of amps, volts, time. The space inside the charger case is both hot and small. An external addon box? A stepdown DC converter to provide 5V for the Arduino (or rechargable battery)? This might be better when the charger fails, it can be easily moved over to another charger.

Digital rheostat + digital potentiometer + digital buttons/switches + Arduino + optional LCD display + small enclosure + 100's hours of time programming and tweaking/troubleshooting? + fun/frustration???

Anyone else consider this? I know it would be cheaper to buy a Satiator, but that lacks the "fun" element.
 
There is a smaller meanwell HLG that is only 2.5 amps that would make a smaller on board charger? I use 2-24v for 480w of charging power. At 10 amps it only takes at max 3 hours to fill my 12s 32ah pack... 8) Where is the best place to get the battery balancers?
