My notebook requires 16V, if I have to use eneloop battery, it would mean 16 / 1.2V, i.e. around 13.3 pieces. By using 14 pieces, it would be 16.8V, should be fine I guess.
Then other devices like my DMK, can be powered by 8 pieces of eneloop, i.e. 9.6V.
Therefore, I will need 22 pieces, i.e. 6 packs. Charging them all requires 3 chargers working in parallel for two times. Not very well.
Maybe I need to buy a 12V Lithium battery pack? But I can find them locally?
