There is a reason for suggestions in manuals. With the heavier 1:8 scale buggies/truggies I used LiPo packs with nothing less than 40C discharge rate. I destroyed six 25C packs in a very short amount of time while putting them to the test in a 1:8 truggy. Extremely puffed cases (split open); desoldered battery cable inputs; too hot to touch cases...I had everything bad happen when using under powered LiPos. After changing to 40C packs...more efficient power delivery to the ESC. No more LiPo packs put into the battery graveyard.
