I'm thinking about getting a five cell hump pack but I don't have a clue on what to get , what brand, what charger etc. What does the number on the package mean 1100 ,1150 etc.? Could some of you guys help me out by telling me part numbers, or sites I could go to and look at for the pack and the chargers that would fit the savage receiver box? What to look for and what not to buy. Basicly, eveything I would need to know to get eveything I need. Thanks for your time in hepling me out!!
