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. … Read more
Here’s another custom Li Ion battery charger and holder. Yesterday we ran a post involving a custom battery holder for cell phone batteries, today it’s a holder for a more conventional 18650 type Li Ion batteries. To make a battery … Read more
Miceuz designed 2 open source single sided boards for Li Ion battery chargers. He used the MAX1555 and MCP73831 ICs as the charging controller, power is provided through USB. We especially like his battery holder rig. For a long time … Read more
rsdio writes: SMBus is similar to I2C, and should therefore be easily connected to most PIC or AVR projects. Highly integrated, 850kHz/500kHz SMBus-programmable battery chargers: MAX17435/MAX17535, highly integrated SMBus™ battery chargers capable of operating at 850kHz and 500kHz, respectively. Unlike … Read more
