So, I scrolled around my phone and found a picture from February when I had initially discovered the adjustment pot. It’s this forward most one circled in red.
Clockwise decreases the amps, counterclockwise increases.
Don’t mess with any of the other ones, the control the charge profile and max voltage. If you screw with them you risk ruining your expensive battery or causing a fire.
I decided to experiment with tweaking my amperage for a few reasons.
- I just wanted too.
- I wanted to see if I could lower the amps for a slow charge that gives more time for the pack to balance cells, since it only balances when charging. Slower charge rate and better balanced pack will increase it’s longevity.
- I charge the battery under my bed and don’t like the noise when the fan kicks on, it’s sorta loud, so I wanted to run the charger low power where the fan would never kick on while I was sleeping.
As a side experiment I decided to see how high it could go and was willing to risk my charger for the cause. I went up in 1 amp increments and observed the temperature of the circuit board components. I got up to 14 when it started to feel hotter than normal. At 14.5 it tripped the breaker for my recepticle.
I plan to make a switch to select between low 6.5 amps, stock 10amps, and high 12.5 amps modes.
