UYaa thanks i use li ion batterys already as i make and use e-cigs but the protection circuit is a good idea iftheres room and as id be using it everyday i'll be puting a voltmeter into the charging stand so that when its plugged in i can check the battery
Thanks for ur help everyone I've just taken it apart again and I am just going to see if i can find a new motor rated for3.7v and the recharging will be easy just replace the circuit with one for li ion that uses a usb port and a fone charger
The 18350 is a lithium ion 3.7 battery that is shorter that the AA size in there and as a hairdresser by trade i wanted the extra power to help cut hair faster
I have an hair trimmer that the battery has died and i wanted to replace it with an 18350 battery for the extra power i just wanted to ask would i need to put a resistor in series with the motor
Cheers tia
