It seemed a shame that the little 10W LED work lights only had two cells when there was seemingly space for four or even six. So I decided to see if I could fit a six cell pack of 18650 cells into an existing light.

    Im doing almost the same thing. Accept i have an old bosch cordless with 3 battery banks. Im just changing the plastic back part with a 3D printed cover for the battery and a dc to dc buck converter. Dont want to let too a high voltage pop the LED.

    One thing that Chinese manufacturers always get right is their ability to glue things together..
    It's almost like the most expensive item in some cheap electronics is the adhesives they use to hold stuff together.

    When you're cutting those combined battery wires, can't you just use a ceramic knife?

    I’m amazed that some people make absolutely nothing throughout their lives 😳

    Just me? School boy snigger for the long screw comment! Plus I had a total Blue Peter moment with the sticky foam pad…we've used double-sided sticky tape but you could use glue or sellotape… Great video Clive! I don't have one to modify but am now wanting to go and get one!

    Hi would this light still work by taking the on off button out? (I’ve wired it up to longer wire’s and plan, in theory to use it with my electric fence battery.

    I have almost the same exact model. Mine only had one battery in it.. I re-used the 3.7v BMS off of the single cell and replaced it with a 4×18650 pack i threw together in parallel. Salvaged laptop cells, but all genuine Sanyo. Battery life is actually usable for work now, charge it overnight and it'll be near full by morning. I could upgrade the 1s BMS for more charging current and shorter charge times but I am happy with it. Besides charging the cells faster will only ultimately give me less duty cycles out of them.
