Dear Members
I am a fellow enthusiast of RC cars.
I come from India and hobby cars are not very popular here because (a) they are expensive & (b) until few years back it was almost impossible to buy them. I am telling you this because even the shop owners have extremely limited knowledge about the products they are selling, making it all the more risky.
I have just bought a Thunder Tiger MT4 G3 monster truck with
1. 4 cell lipo battery 4000 mah
2. IMAX B6AC charger
Now, I have a few questions and I will be greatful if you can educate me a little bit.

1. The motor says 2000 kv on it. What does this mean?
2. The lipo battery is 4000 mah and reading at many places in this forum I understand that I should charge it at 1C per 1000 mah. 4A in my case. Excuse my ignorance, but I just need some clarification. .... 1C = 1A or 1C = 0.1 A?????
I ask this because the shop people set up the charger for me at 0.4 A, but after reading extensively, I feel that it is wrong.
Now, this charger is capable of charging 6 cell batteries also, but has current rating of 0.1 to 5 A. So that means it cannot charge a lipo 6 cell at 1C.
3. How long should a lipo battery take to charge normally?
4. If on fast charge, what really changes in the charger that enables it to charge the battery faster?
5. Is it okay to balance charge the battery each and every time?
6. If you know this charger, kindly clearly tell me if it auto cuts the charging after reaching the optimal voltage level in the battery?
7. Finally, I will be able to use my RC only weekly, so should I keep the battery on 'Storage Mode' all the time, or is it okay to just leave it discharged for a week? I ask this because my reading tells me tht it is not a good idea to leave the battery charged.
I really hope someone can help me.

Thank you for your support and suggestions.
