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?
It means for every volt the motor receives, it will turn the kv rating, in your case 2000 times.
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.
1C for your battery would be 4.0 amps. Yes, it can charge a 6-cell at 1C, as long as the capacity (mah) is no more than 5000mah. A 5000mah pack at 1c would be 5 amp charge rate.
3. How long should a lipo battery take to charge normally?
At 1C, about an hour, at 2c about 30 minutes etc.
4. If on fast charge, what really changes in the charger that enables it to charge the battery faster?
Charges at a faster rate than 1c. Alot of chargers these days can charge way over a 1c rate. I never do tho as i have an older charger.
5. Is it okay to balance charge the battery each and every time?
Absolutely, you dont have to, but alot of people do.
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?
Yes, it will shut off automatically.
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.
You will get alot of anwsers here. Alot of people like to strore them at...i think its 3.85 volts per cell. Some people leave them fully charged, so dont really have a set preference. Your charger may have a storage charge setting on it.
Hope this helps a little.
Thank you for your support and suggestions.
