A 3.6V LiFePO4 charger for under 50c

Monday, January 4th, 2016

Nerd Ralph built his own 3.6V LiFePO4 charger: I like LiFePO4 batteries. They have a rather flat discharge at around 3.2V, which is ideal for powering 3.3V devices without a regulator. You can also use them in devices that take 2 standard AA cells by using a blank shunt in the...

LiFePO4 charger

Tuesday, October 6th, 2015

Markus Gritsch shared his LiFePO4 charger project in the forum: Since I really like using LiFePO4 AA and AAA batteries in some of my projects, I finally gave in and built a dedicated charger for them. Previously I used a lab power supply to mimic the constant current/constant voltage charging curve, which...

Lithium iron phosphate (LIFePO4) battery charger

Thursday, February 7th, 2013

After two DIY Li Ion chargers this week (first, second), here is a lithium iron phosphate (LIFePO4) battery charger. These batteries are a safer cousin to the standard Li-Ion batteries, but sacrifice some of it's energy density for the safety. The charger above is designed around the PIC12F510 microcontroller which...
