You got a special ROT66, I only got 3 cells in mine
I had an oopsie yesterday. Testing the Keeppower 6000 in my D4S then putting the 5200 back in and had it reversed, positive to the tail cap. I almost tightened all the way then when the Aux Leds didnāt come on it triggered my brain and I undid it with heart in throat. All good
The D4 had not full reverse protection, the driver protects itself but the battery drains at quite some amps (I believe it was 8A). So if noticed immediately it is no problem, but if kept like that you have a big problem. There was talk about this being improved for the D4S but Iām not sure. Easy enough to test with the tailcap off and a clamp meter (donāt have a D4S myself).
Out of curiosity, would it be possible to order one of these without the emitters? Could you ask Barry what the price would be in that case? Iād only be getting one to swap something else in, and I donāt want to pay for emitters Iāll never use.
People seemed pretty exited that Sofirn was selling parts .. i looked and my first reaction was the parts weren't all that cheap and just buying a light is going to be about the same as the parts you want.
I kind of find this to be true about most hosts etc for sale.like a s2+ host for 10$..doesn't make much sense not to just buy the whole light.
I gave someone an original SRK once. It came back a few years later with two toasted springs because someone put the cells in with alternating polarity. It should be obvious at a glance which way the cells go, given that it has all the springs on one side and a solid contact ring on the other side, but apparently thatās not enough of a hint.
They donāt sell 30Q. Only their own cells. They have a high drain 3000mah button top. It has gotten some good reviews. Almost the same as a 30Q in amperage. Link to the main Sofirn store.
Iām sure most people have found out by now, the Sofirn is for sale now at aliexpress for the discounted price, by following the instructions in the OP. For completeness I wrote an update in the OP also.
For the Amazon buyers it will take another week before the lights are there.
