Here is the deal...you probably have a mis-made battery sled.
First battery sled I received just didn't work. Just wouldn't light up (there are very visible LEDs on the board) and would not power my GH.
So,
@maxvapor710 sent me another one (I have absolutely no issues with their CS).
This one wouldn't work either.
They asked me to try to power it via a wall wart and the USB port on the sled. Well, fuck me...the both lit up like Christmas trees and powered my GH just fine.
So, I take very close look and see that the sled seems a bit too large for my flat top unprotected 18650's and the positive terminal of the battery was not touching the contact. I get out a screw driver and pry up the negative spring type contact to try to tighten up the battery fit. Didn't do anything and now I'm looking very closely at the positive terminal.
Unlike the negative terminal which was the spring clip type, the positive terminal was a flat piece of metal with a small protruding dimple that fits down in a slot in the plastic of the sled. The dimple did not protrude toward the battery beyond the plane of plastic terminal holder.
There was absolutely no fucking way a flat top battery would work in this thing. And indeed, I have two protected batteries from my G43 and on these the positive terminal does stick up and they fit and powered up the sleds perfectly.
I reported this to
@maxvapor710 CS and got the reply that both terminals in the sled are to be the spring type like the negative terminals on my sled and that their supplier fucked it up and shipped some in one configuration and some in the other.
They will send me another in a week or so after they build some more boards, etc.
Long way of saying that if you are fine having to use protected 18650's, then you are set. But the device was not intended to use these by design and I feel confident, that if you want, Max will send you a corrected one after they sort through the good ones from the bad.
The part I don't get is that the company told me that they do indeed test every sled before sending out. Well, maybe with USB power or protected batteries (which would make no sense as its not intended to use this style of battery) because the two I have would definitely NOT work with a flat top.
Cheers
