Cost bro! U pay more for more Cells n C rating. The more Mah n cells the cooler the system will run. U also need slip diff if not your gears n cvd will wear out fast ESP with so many cells.

So your car is heavy, wear out faster n can't have long run time.

The cost and weight are about the same!

With the 1521 1.5y I would buy two turnigy 4s3000mah40c packs
weight: 720gr
cost: $76.52

With the 1518 I would buy a single 5s5000mah40c pack:
weight: 704gr
cost: $76.82
