There’s some generality here, but specifically this is for P639-F025-ND, batt pack with 10 C-size NiMH cells.
How much current can the battery pack deliver and with what consequences. I’m not asking about the Panasonic cells, I’m asking about further limitations resulting from them being in the pack – most specifically related to the 9 interconnections between the cells, and to the 2 output tabs, and to anything else I’m overlooking. To be more specific, in one case: I expect to draw about 18 amps for 8 seconds; 0 amps for let’s say min 22 seconds; repeat that cycle up to 5 times; then 0 amps for many minutes or hours other than some low-current recharging. I want a) to be confident that none of the interconnections will be degraded, and b) to know how much resistance … like, milliOhms … is introduced by the pack (I’m not asking about the cells’ resistances, just the added interconnections). Or, if that resistance is dominated by the materials and not the welds(?), then if I can know the interconnection materials & length/width/thickness, I’m fine calculating it myself.
What are the diameters of the holes in the + and - output terminals of the battery. I’ll be choosing wire gauge and deciding whether/what multiple wires into each terminal. We have battery packs but I’m not at the site where we’re keeping them, so I can’t measure.
On this and other products’ DigiKey webpage, I see “Note Battery packs made with NIMH cells include a thermostat”. Could that actually be true, or is it a mistake for this pack and others? If it’s true, then I’m interested to know whether/how there’s electrical access, and/or other details.
