One pack gives nominally ,3 hours and two packs nominally double that. In practice you will get somewhat more than double as effective mAh rises as load drops. | Note that 5:cells is about 6b when new and 5 Vat end of life. | |

| Dec 1, 2021 at 7:53 | comment | added | Lorenzo Marcantonio | It's not negligible since internal resistance of the batteries is not constant. If you look at a typical discharge curve usually a battery discharged at C/5 lasts more than 5 times the discharge at C. It really depends on the chemistry. But consider that some kind of batteries don't really like to be connected in parallel (that's why we see lots of series with maybe cell balancers) | |
