if your hard on your truck you dont want those unprotected packs.
you want hard casing aroun the lipo cells.
there is trakpower( part of flightpower) and there is orion and peak.
the latter 2 or the same brand actually.
i have the orion 2s 3200, they are about 450watts continu.
the trakpower is 700 watt continu.
if you would get the LIMN 3s 3800mah it would be around 684 watts.
so trakpower is less speed but more power(torque).
chose what suits your needs, more speed, more overall power.
