I get fairly short run time out of my dagger compared to single motors.

Running a normal esc with power input. How can I modify my dagger to receive two power inputs? Is it possible to run one power to each motor with one esc?

Cheers.

you could make a Y harness that would allow you to run two batteries at the same time. As to whether it would increase run time over running two batteries back to back is a toss up. The extra weight of carrying the 2nd pack and the fact that as motors heat up, they become less efficient would have an effect

This is an age old debate, 2 packs in parallel or stop to swap.

The extra pack provides more weight, but if you use cheap batteries like I do, having 2 in parallel may seem more powerful since the amperage output from 2 packs is higher for a given voltage. The cheap($15-20 stick packs) do not keep their voltage up well when subjected to higher loads such as dual motors. There should be a lower voltage drop under heavy acceleration with 2 packs in parallel. This may actually increase useable runtime more than 2 single packs run separately since the packs are less stressed and should not heat up as quickly.

Using 2 stick packs in parallel is the same Idea as Li-po battery packs, they regularly use configurations which have sets of parallel cells in series to get the voltage and capacity they want with a good enough constant amp output level.

The high-quality matched side by side packs would likely benefit much less from dual packs in parallel as they tend to keep their voltage up better than the cheap packs.

Of course this is all untested as I don't have the time to do any proper experiments. . .
