Well, with all the stuff arriving batteries must get charged. I already read overhere of the flimsy chargers that came with with most lasers but I wasn't prepared for 330mA charge. This is my solution.
It's an fully adjustable LiPo charger from the Remote Control world. For now I can only charge one battery at a time so that needs improvement. The charger can charge up to 5 LiPo cells with balancing. I am pushing this 26650 with 2.8 Amps.
The similar B6 type R/C Li-Po chargers can charge 2 to 6 cells.
It would be easy to make a suitable 2 to 6 cell holder and
attach a balance charger cable to monitor the voltage of each
cell as they charge...
