My aim is to test the capacity of any lithium battery I buy before I put it to use.
To get a happy balance between time/current/capacity, I settled on 20 amp draw to test my batteries.
Why 20 amps? Cuz that is my average draw and I had everyday items which I could use to test at that draw.
I can use this to test EVE 280ah, Litto Kala 100ah, A123 batteries or even my scooter packs.
What I used to test:
1. Desktop heater (walmart) - 200 to 300 watts ($10)
2. 400 watts modified sine wave Inverter (I picked this up in the late 90s from a mega truck stop in Iowa around Davenport) ($30)
3. DC Power Analyzer (eBay or any other source) ($10)
For a total of $50, I can test the capacity of my batteries and when I am done, I can repurpose those items.
Here are pics of the components:
Next: I will demo a simple setup of the above.
