  1. Hover mouse curser over area indicated by red arrow and report back what the voltage reads.

    Also it appears that the standing voltage of your cell is 3.66 volts, with a 75 ohm load it very well is going to drop to below the 2.75 volt cutoff and do exactly what you are posting about, throttling down.

    Does charging the cell to full charge correct this problem?

  2. Even though your charger outputs 4.5 amps the board will never draw more than 2 amps, so no problem.

    Pay attention to cell voltage rather than percentage, 4.1v -  4.2v is full charge. If they are not close in voltage between each other charging will appear to stop while it balance charges which is quite slow.

    One more thought, have you tried using a different cable?

  3. As Bill said "batteries can explode" and those salvaged laptop batteries are of the chemistry that does it best. Laptop batteries are generally  4 to 5 amp continuous discharge rated. To supply 100 watts from the board cells with a rating of 15 amp minimum would be required. Personally I would use 30 amp rated cells. You are running a huge risk by over taxing them. If you want to salvage cells from something power tool batteries would be a good source, though I wouldn't recommend doing that either.
