A friend of mine wants to have a 2nd battery for his saber.( he works at a movie theater and will be dressed up for next weeks release)
I was wondering if i could wire a recharge port up to a female JST connector and he could us that to charge a second battery outside his hilt.
He has the 3.7v charger and will get a 2nd 18650 3.7v battery from the shop
Is there any problems that may arise from this or will it work? Has any one tried it?
Thanks for any advise?
