LiPo Fuel Gauge (MAX1704X) Hookup Guide

February 23, 2023
Monitor your LiPo battery with the LiPo fuel gauge! In this tutorial, we will be using the MAX17043 and MAX17048 to monitor a single cell, LiPo battery over the Arduino Serial Monitor. We will also connect a display to view the output without the need to connect the microcontroller to a computer.

    Would it be possible to use this to connect a battery to a female usb port?

  • dwavo / about 9 years ago / 1

    i bought these to use with the EL-sequencer. They are a little difficult to seat because of their size (2mm centers) but if you want 8 connectors on a board that's what you'll live with. they are a little tight and you need to really wiggle them in and out.

    sparkfun wish list - make these with zip-cord style wire instead of this twisted, and longer lengths. sell them as 12" extension cords with male/female so that el-wire can be extended. sell the female side as well.

    Can you please tell me if this jumper fits the EL Escudo Dos?

    • RobertC. / about 10 years ago / 1

      Yes, the EL Escudo Dos uses these connectors. They are JST PH, you can find others on our site by searching that.

    The connector on mine seems to fit EXTREMELY tightly in actual PH headers bought from JST (not just clones.) Like, you need to use pliers to get it out. Has this happened to anyone else?

    • shilbert / about 11 years ago / 1

      Answered my own question. From this sparkfun tutorial:

      If you've ever tried to pull a JST connector from a JST socket you'll find it's incredibly difficult. This is because JST connectors were designed to be used deep inside electronics where a battery or component may need to be changed only once or twice within the lifetime of the product. A very strong, firm connection was more important than ease of removal. We use JST connectors specifically because they have such great holding and are so compact!

    This doesn't come with the mating connector.

  • Member #231006 / about 13 years ago / 1

    Does anyone know if this JST connector fits on the Li-Po Battery charger/booster that is sold by Sparkfun?

    • SFUptownMaker / about 13 years ago / 3

      It will- this is the 2mm pitch version.
      http://www.sparkfun.com/products/9914 works as well; sometimes the untwisted wires are a little more useful, and it comes with a male header, which this one does not.

    Got some in hand: Mine are 24 AWG stranded with very short pre-striped and tinned ends.
    Has markings (in no particular order):
    XIEHE AWM 1007 VW-1 80oC 300V 24AWG XIEHE FT1 LF
    Only on red wire: E251491
    Only on black wire: 5251491
    Some UL data matching my pigtail wires.

  • swolpert / about 13 years ago / 1

    What type of wire is used in this cable? What gauge, whether stranded or solid, etc. Thanks.
