I run shorty packs in my two buggies and SC trucks, so I have a good selection to choose from to get the weight that works the best for my setup/track. Most of them weight between 200-210 grams with the Promatch 3500mah being the lightest at around 155 grams and the RevTech being heaviest at 210 grams.
Losi Xceleron, ProMatch 4800 and 3500mah, Turnigy 4.2, RevTech 5000mah, Venom 3800mah.
