Typhon Confused about packs

[sxndrog18]

Hi guys new to the hobby and was wondering how many times I should change my diff oil? I run a typhon 6S on grassy terrain not very often (2-3 times a month) involving light bashing. I read Around 20 packs but how long exactly is that? What is a pack?
Thanks

A pack is one battery or charge. So, 20 packs = 20 charges.

Nice thanks man. Also I’ve noticed my typhon is very loud at low speed is that normal?

Check all moving parts including your pinion/spur mesh. If the diffs sound loud, time to open them up and inspect everything including bearings and the diff cup bearing race, mesh/shims and inspect the ring and pinion teeth.

My 6S EXB gears are loud..to me louder than my Kraton 6S EXB. As posted above, if your diffs check out fine, gear spacing is correct, no binding you find when the driveshaft/wheels turn, etc. it is normal.

For mine, what I came to when I broke it all down.
