Great instruction video! Thanks

[@calumknott3519]

Thanks for this video, very helpful, are the settings saved when you power the device off, or do you need to reset the paramaters each boot?

Does this accurately measure the real capacity? thanks

[@dojmike]

Do you have the power supply specs to fire the unit up? Voltage as well as minimum amps? Thanks.

[@mpjaonline]

With the fan running it can draw ½ Amp at 12vdc, Here is a link to the datasheet. www.mpja.com/download/35875tedata.pdf

Its up to 30V

[@tpcdude]

You didn't show how you were powering the unit itself, maybe that was obvious but where do the battery leads go? can you use a 9v battery supply?

[@mpjaonline]

Look at about 28 seconds into the video to see where power is connected. It will work with a 9v battery but at a 25mA load it will only last about 20 hours.

[@gunnaralv]

Why does it drop voltage so much? Now I am testing a LiFePo4 battery, but at 1A it drops voltage from 3.3V to 1.61V. So UVP will kick in before it has drained the battery to its limit.

[@mpjaonline]

I can’t answer why your battery drops so much with a 1Amp load with out a lot more info. You can change the factory LVP set of 1.5v In the video it is at 7:15

You are unfortunately, the owner of a dead battery. If you flatten a LIFE battery you will kill it.

Hello 👋. you talk a lot, but my knowledge is nil. so if you could tell me what is connected left and right. THANK YOU FOR BEING HERE ❤️ hello from Europe 👋.

[@freytube1]

canit be set to constant current in MA range ?

[@mpjaonline]

Yes and no, minimum resolution is 10mA with an accuracy of +-1% and 3 LSD make it possible up to 40mA off. Thanks, MPJA
