    Oregon has a HUGE catalog with a lot of good info. Will give you part
    numbers to search for not commonly found at most dealers.

    I'm actually using an Oregon blade and chain on the 20V DeWalt saw. It
    was an easy affordable way to run a blade a little longer than the stock blade, without going to a more expensive saw. I do have to let the saw
    do the work, but its a cordless after all. Probably wouldn't have been
    of much utility if I hadn't invested in the 8AH XR batteries. The 4 AH batteries were what gave me the clue since they worked on other power
    hungry tools better than the 2 ah batteries most of them come with if
    they even come with a battery.

    ---------------------------------
    Here's some technical discussion of DeWalt battery innards, though it
    doesn't mention impedance. If they increase capacity by adding parallel
    stacks of the same cells more stacks will reduce the internal impedance and voltage loss. https://www.reddit.com/r/Dewalt/comments/1ershh9/dewalt_battery_schematic_temp_and_low_voltage/

    The small medical Li packs I worked on had 1000 Ohm resistors across the
    cells that the control circuit could switch in to balance them during
    charge, by allowing part of the charging current to bypass the higher
    voltage cells.

    The batteries recorded their use. Those left in a hot ambulance in Arizona could lose capacity in less than a year.

    That's a fundamental law of nature. Arizona kills batteries.

    A buddy of mine is a retired fire captain. (Mostly drove ambulance.) I
    might ask him what sort of portable battery tools and equipment they
    carried and how they held up. I seem to recall all (most?) of their
    fire stations have indoor parking for both ambulances and firetrucks.
    Maybe that might throw off the results. Shade makes a huge difference
    in cabin temperature.
