    4.2V 4S Li-ion lithium Battery balance board balncing full charge Circuit 16.8V

    Nice and cheap, works well.
    The 62 ohm 1 watt resistor is the balancing load. You DIY an additional 0805 47 ohm resistor with a 0805 white LED, to see the balancing in action. balancing voltage (4.2V) is accurate, and has a -ve TC

    Good 12 AWG copper wires, good heat sinking with metal core PCB, one of the better ebay products! Bargain!
    LiPo Fuel Gauge battery detection module A/D conversion IIC MAX17043

    Nice cheap fuel gauge.
    Similar to Sparkfun's version right down to silkscreen logo, work like a charm (accurate enough), but... The I2C pull up resistors (SDA, SCL) goes to battery voltage, the pcb trace has to be cut, or depending on whether your GPIO pin has internal pull-up (e.g. RasPi), an additional wire be soldered and driven at IO supply rail.
