Assembled Marwi P7 lights, battery holders and Chargers
Note: All the Marwi lights I build run on 3.6 volt battery packs.
You cannot run my designs on anything but 3.6 volt battery packs.
I do not make or have any driver designs for higher voltage battery packs

This is what the Marwi lights look like with a power cord and a Marwi straight mount added to the light body.
The light does not come with the Marwi straight mount shown in the picture.
You have to choose which style mount you want.
I am adding 36" power cords to the lights so that it will reach down into backpacks and water bottle cages.

It holds 4 x 18650 batteries. Two on each side.
The power cord exits from the middle of the battery holder.
The perimeter is wrapped in black electrical tape to keep the battery tabs on the ends from shorting out. The power cord is approx. 12" long
The picture does not show it, but the battery holder has a 13" Velcro strap that is hooked to the body

It will charge all four batteries in the battery holder at the same time.
