lipo battery
 

Hi I am thinking of buying two 3200amh 2cell 20c lipo batterys
They are the hard case stick packs

Will they be ok to race a 10.5t brushless motor
I will be racing 4 races and then a final in a day
The races are around 5min long. Will they last that ??
Their is about a hour between each race. Will I have them charged in that time. ??

Also
I thinking of using the stick pack because I am racing a old chassis but it can be cut to fit the square packs. Would I be better with the square packs ??

Thanks

You don't mention what kind of car you are driving, in my experience with a 10.5 turn in a 2wd buggy, we are using around 1500 to 1800 mAh during a 5 minute race. My sons driving isn't the best so some of race is waiting for marshalls! but a 3600 would be ample to finish a race.

A 4wd will use a bit more and a truck a bit more again I would guess.

We use 3 packs, one for practice and 2 for racing but we could get away with 1, it's just that having more takes some of the stress out of the day.

2 would be plenty.

By square, I assume you mean saddle packs? Saddles are more versatile as you can use them in any chassis type so if you think you may change car in the near future, it might be better to get them and you won't need to buy new batteries.

i will be runing a 1/10 touring car
so i should be ok with two packs
i am just getting back in to racing and if i like it again i say i will change the chassis in a year
how many years will a lipo do me for if well looked after
