Stingo Solid State Battery Charger

[cikljamas]

Congratulation . How much current needed to be as bright as it normally do?

I think it is (on the picture) bright as it normally do (220 mAmps),maybe
i am wrong, but if it is not highest brightness than it is at least 80 %...
What are your results, i mean how much mAmps you need to make stingo
to give such level of brightness ?

Try it with bingo too .

I tried, but it doesnt work and i think that bingo can not be use for that purpose at all, that is one of the stingos advantages, but my measurements
insure me till now that bingo has much higher efficiency charging big batteries(especially with negative to negative THANKS FOR THAT CLUE),
and slightly higher efficiency charging nimh batteries, at least using 12V
battery as the source. Using nimh batteries as the source it seems better
efficiency is on the stingo side, i did not make that kind of measurements,
but i do not have any reason not to believe you.
But if you have just one ampmeter it must be very difficult to make these
measurements, am i right ?

I tried stingo with negative to negative, but something is wrong when i
try to do that, and something is wrong this way also with bingo when
i try to charge nimh batteries using 12 V as the source, too !

Cheers !

captret

Sucahyo, i forgot to ask you about captret implementation with stingo.
Did you tried that ?...And if you did how you did it ?

Worse, my record is full brightness at 240mA but never been able to reach it again. Mostly 500mA now.

It is weird that bingo can not be used....
Check my video on bingo thread on how I do it .

Yes, when the circuit do not oscilate, the load still being charged, without the radiant. At least that is my reason not to use negative to negative.

I never try it.

Capacitor is the worst load for stingo, draw current most then other load. see if bingo better.

Stingo

Stingo I found that is better than JT and Bedini solid state cause batteries are holding voltage it seems. Still testing. The thing is that from a 12v battery with 7v charge on it still works.
Sucahyo do you know of a good and simple battery swapper?
Did you manage to charge dead batteries to each other with stingo?
Thanks

I think it happen because you charge with single diode. I think JT or Bedini solid state will also retain battery charge if you use cap isolated FWBR.

Mine had around 7V charge too. When I open the cell, I see only 3 cell are good, the other one shorted because of heavy corrotion...

I try once with old version of stingo and produce result of declining battery.
YouTube - Swap Charging front and back battery

I use relay with 4 contact point, FRM3-4B5. I use toggle switch but should be easy to add 555 control, just being lazy .

If I try it again, I would use latest circuit and add ungounded water connect to load positive.

I tried to run cfl with stingo today again, and it works just like it worked
yesterday, and it works well with one weak transformer, i even think of
buying 2*9 25 VA transformer that i used for building one 12/220 inverter
a few month ago, to test stingo and cfl with it too...Also drains 220 mA,
as yesterday, so we have confirmation that it works well indeed !

Check my video on bingo thread on how I do it .
.

I tried bingo too with cfl, but it drains too much current and frequency
goes up and down too wild, so i gave up trying to find sweet spot for
cfl lightening with bingo, and why should i in the first place since i can do
that so successfully with stingo ?

I checked on bingo thread but i cant find where you demonstrated
bingo lightening cfl there ?

Rgds!

ok

Full brightness at close to 1 watt is something you should brag more .

I see. thanks for the info.

I find that bingo can power car coil easier today.

Sorry, wrong word, the video show how I swap the amp meter.


BTW, my on of my double stingo charger transistor die yesterday, because I left it run without load too long. I replace KSC5027 with 2SC3866. It turn out bad, now the total output is only 300mA, while it is 450mA previously. I don't know if this just coincidence or show how supperior KSC5027 is.

For Bedini charger a BR and cap would be ok and maybe one of the reasons as you've said but for JT it gives out DC current cannot be hooked to a BR maybe a cap only then?

I once did a relay for a swapper but there were too much sparks when switching the batteries and I discontinued to use it.

My JT produce pulsed current. A switched coil produce huge spike, followed by much smaller reverse spike. While 7imix mention almost no reverse spike for stingo, adding cap isolated FWBR still double the efficiency.

But if you connect load negative to source negative, FWBR may not be useful.

For what implementation is that?

I don't notice that, I don't see spark. When I turn off the load, the source is disconnected too. When I turn on the source, the load get connected almost the same time, which should be faster than cap dumping time. There is less time for the output to build up voltage to make spark, especially because the source power is just being connected.

PulsecircuitBR

Hi Sucahyo sorry for too much questions and rough sketch but really want to do the best charger for my batteries. I'm posting circuits to be sure how FWBR should be used. Better AC caps as used on stingo then Electrolyte to BR?
Thanks for your response.

That kind of FWBR is less efficient than my last posted one. You get more power, but also consume more. The purposes of capcitor on my FWBR combiner is to prevent the source directly charging the load.

If you use like those picture, the source will charge the load even if the circuit is dead / do not self oscillate. Putting the cap in series with the FWBR is better.

Blocking only the source like my latest version I thinkonly applicable for circuit that has consumption reduce with load, like stingo or tuned SSG.

The capacitor need to be able to sustain 400V from coil collapse, but only 12V (source voltage) from source. Because I am not sure if electrolytic can sustain 12V in reverse polarity, I can only suggest non electrolytic.

On that joule thief, FWBR do nothing, because current flow one way. If you connect the JT output the same way as SSG, FWBR usefull.

Compare all if you have doubt.

I use two stingo before and I get good result. I use three now and I still get good charge and moderately cold battery temperature after fullly charged.

I don't use SSSG or JT as charger because I found stingo more efficient.

Hi Sucahyo is it possible that you post a schematic regarding JT how to be with caps and FWBR cause I had built these already and I want to use them? In future I will change them to Stingo.
Thanks

Ok. I will post it tomorrow.

It is similar with normal FWBR except you place a capacitor between the FWBR and coil-battery positive. The other input of FWBR connect to coil-transitor.

Here is the JT picture:



Here is my battery swapper suggestion:



Put volt meter to both battery.

Jtcap

Hi Sucahyo thanks for your posts I will do that cap and FWBR to my JT.
Thanks
