    I used arduino UNO and i am getting SOC: -1.00%, VCELL: -0.02V as output and nothing else please help

    i found I2C address at 0x32 ,it didn't work even though i changed the address from 0x36 to 0x32 in the library

    Can i use this sensor for my solar panel battery (12v 40Ah)?????if not pls suggest a solution.

    FYI. They are just €2.10 on Aliexpres

    Why do some people change the R3 resistor for low MAH batteries and some don’t. Thanks

    hi. i know this is a old video but i was wondering if you could upload a wiring diagram of the fuel gauge, charger, battery and arduino. i am hoping to do similar thing for a project myself now

    Is it possible to connect a solar Panel on the LiPo charger and switch automatically between solar Panel and USB charging??

    If I build a battery bank with multiple 18650 batteries in parallel, can I monitor them with a single MAX17043? Would it provide a correct soc readings?

    Can I do the same for automotive battery (car battery)? I'm trying to create a system to estimate its lifespan and capacity.

    You could desolder the jst connector from this to make it even slimmer. Got one of these myself and one Adafruit Lipo battery and one I ripped out of a tiny video camera. I'm probably going to experiment with this this week.

    Julian how to use 2 max 17043? Can i set two different slave address to each one? Thanks. I need to monitor two battery at once using arduino nano.

    Questions:
    Why is it for LiPo? Does this mean that no other battery pack can be used?

    Hi Julian,

    I always enjoy your vids. Do you know if there are any Arduino groups around west London? Also, can you recommend any books suitable for someone hoping to take electronics a bit further than the absolute basics — I'm thinking something like a general practical handbook of the handiest circuits and ICs. Looking for books on Amazon or ebay is difficult because you can't easily flip through them to get a feel for which ones are going to be useful. (The ones I've bought so far with promising sounding names have turned out to be a bit of a disappointment.)
