I am wanting to build batteries in a project to supply 9 volts.
I looked at AA and PP9 batteries and then came across lithium version of PP9.
Are the lithium batteries the best choice for getting 9 volts? Are there fire risks on battery discharging too low? Can I use a normal battery charger that takes ordinary PP9 batteries to charge these batteries. I will be drawing some 72ma when the unit is switched on (by a switch) It's a wireless remote control so use when on will not be lengthy. Thanks
