Battery for Convoy L21B PM1 & SFT40 models prior 20/07/23

These are specially for the Convoy L21B PM1 & SFT40 variants that I sold prior to 20 July 2023. All new stock uses this battery.
 
I had installed a spring inverted since this was the only way to allow gun mounted use for these two lights at the time. They were released to be only for handheld use, so I had to modify them. The large button top helps it to make a connection to the spring and also provide reinformement to the top for mounting (see 2nd image). A regular flat top 21700 can still be used, but mounting it is your risk.
