parallel or series
 

I'm like everyone else and want more run time. Not really looking for top speed. Running 2s 5000 25c on a MM 2650, losi buggy. Will I get more run time with two batts in parallel for 4s, and speed with series.

2 2s packs in parallel would give you
7.4v and 10000mah


You would be going slow as dirt

But have double the runtime

If you aren't exceeding the capabilities of your batteries, I would only use one at a time and then switch them out when you need to. The set up will be lighter and perform better, but still have just as much run time.

I have been changing out batteries. Getting about 15 min on each one. I thought about putting inline switches accessable from outside the car to each battery then just switching batteries easier without having to take off the body and change plugs.

The switch idea doesn't make sense...but at least you're thinking. :mdr:

If you're putting both batteries in the truck to begin with, just run them in parallel. That doubles your run time. :yes:
