the need of “special cells” is mentioned at banggood – so have them prepared
word is that a bridged rear spring can make more cells to work
for that small ammount of money you get a lot of light – but you can see that its a cheap one
(but still better made than the JM30 was)
unfortunately i could not get a view of the driver (the lights will be given away so i can´t destroy them)
