SheKor Charger for 18650/17670/18500/17500/14500/16340/
I have been looking at this charger for some time , what I found interesting and tempting , was the input voltage range . For some time now I have been thinking of a Solar Powered Charger , and the main stumbling block has been finding a host/charger suitable for such a project .
Im not going there today , but will rather evaluate the charger as is , for anyone contemplating owning this charger .
To the pictures :
Now in all fairness they make a lot of claims on the side of the box , and it would be real nice if it was all true , real nice .
Im draining a battery as I type this so as to start testing the charger .
Ok some results :
Open current = Bay1 or left side as pictured was 4.13 to 4.14v Bay2 or the right side was 4.16 to 4.18v , voltage for both was the same as open voltage with a 18650 in place .
Bay1 18650 @ 4v = 0.16A
Bay2 18650 @ 4v = 0.17A [ Now the second bay did hunt around a little with the amps going up and down but then stabilized at 0.17A ]
Bay1 18650 @ 4.17v = 0.0A
Bay2 18650 @ 4.17v = 0.0A - 0.01A , again hunted around a little between 0 and 0.01A and then settled on 0.0A
18650 @ 3.84v = 0.33A for both bays .
So looks like constant voltage and variable Amp's , so the closer you get to termination , the less Amps . And it does look like it will shut down when its done .
I will charge some batteries , and test as we go along , I only just fully charged all my batts recently so I have none that are run down unfortunately .
So just waiting for a RCR123A to run down ATM .
RCR123A : [ One bay only being used at a time , I will do dual bay testing shortly ]
RCR123A @ 3.75v both bays charged at 0.37A
RCR123A @ 3.57v Both bays = 0.44A
[ I would just like to say the over discharge protection works on my Trustfire Red and black RCR123A ]
RCR123A @ 3.22v , both bays are charging at 0.47A
Dual channel Charging [ 2 Batteries ]
With the 18650 occupying one channel/bay the RCR123A was getting 0.46A in either bay , which means its a true dual channel charger .
With the 18650 @ 3.86v and charging at 0.32A on its own , with the RCR123A occupying the opposite bay it was doing 0.31A to 0.30A , again dare I say true dual channel charger .
I had the RCR123A in Bay1 which had an open voltage of 4.13-4.14v and as I thought it terminated @ 4.13v there was 0 charge at termination [ No trickle charge ] , and it is independent from the other channel .
The open voltage was higher on Bay2 so I wait to see if the 18650 comes in at 4.16v .
Ok the 18650 has finished charging and came in also at 4.13v , and the charger again shut the charging channel off .
This could be a safe charger , I say could as you should never leave a charger charging for too long or you just may burn your house down , I guess they just cant be trusted . But this is the first one that I have actually seen that shuts down each charging channel on completion . Its certainly not an expensive charger , and for my intended purpose of hooking it up to some solar panels and just placing it outside to leave it to do its work , it looks like it just might be a good choice .
So in the coming months keep an eye out for a solar charger :
