Battery help please?
 

Hey, guys. I have a couple of questions regarding batteries and charging. Bear in mind the questions I'm asking is for a toy grade RC:

1) I have a 600 mAh battery that's getting me roughly 13 minutes run time. If I upgrade to a 1600 mAh battery, barring the added weight because of the higher capacity, and I run the vehicle the same way as I did before would that theoretically multiply my run time by 2.66 times? If not, about how much more run time would I be getting?

2) The charger I am currently using has an output of 12V DC 350mA. About how long would it take to fully charge the 1600 mAh battery and how long should I keep it on the charger for the initial charge?

I'm sorry if these are stupid questions but I am totally new to this hobby and all this is a learning experience for me. Thanks for any help I can get.

What type of battery is it?
What is the voltage of the battery?
How much is the upgrade?
A link to the battery upgrade?
Connector type?
Would you consider getting a multipurpose charger, good for many applications and battery types including car?

NiMH - Nickel Metal Hydride - 1.2 V Cells
NiCad - Nickel Cadmium - 1.2 V Cells
Litium - LiFe/LiIon/LiPo - 3.3-3.7 V cells


Answers:

Yes if you have a 600mAh then a 1600 = 1600 / 600 * existing runtime
If you have a 1600 12V charging at 350 mAh = 1600/350 hours charge time


Post Notes:

A multipurpose RC charger can charge a 1600 in less than one hour.
A lithium polymer 11.7V pack can be as small as a NiMH and pack over twice the current capacity.
You could be over capiltalising your RC model, but then a smiling happy experience is priceless!!

Smart charger and u are gooood
