It would be nice if I could charge it from the top without having to open it up every time, but not sure how I would going about making a suitable charger.

If you know the mAh of the cells you fit, you can trickle charge them using a bench PSU as a charger. You set a low current and time it with about 40% over charge to counter losses. I do the same and it works well. Takes about 16 hours. |
Thanks Ian. I currently don't have a PSU with adjustable current but can continuouly adjust voltage from 1.5 to 9 volts.
My cells are 1.2V 2000mAh. Is there any other way of limiting the current and how could this be calculated and set ?
