Walkera 4 3b Battery
What is the charge time on a 3.7V 400mAh Lipo battery for an RC helicopter?
I just bought a micro Walkera 4#3b RC helicopter and a Walkera LAMA 2-1. I was curious to know how long a 3.7V 400mAh Lipo battery takes to fully charge up?
Depending on how much you drained your li-po battery, will vary on the charge time. I hope you do not drain the battery all the way down because if the battery is below 3.7 Volts, then you could risk blowing up the battery, or damaging it. But typically it takes about 45 minutes to 1 hour to charge the battery (1 cell batteries do not require balancing).
You have a li-po battery, and the charger should come with a indicator that has a red light indicating its charging and a green light that turns on when it is finished charging. Not having an automatic cut off charge is dangerous and could result in a fire. Refer to the manual if you still have it. I recall testing the Walkera product, and its suppose to have a light indicator. If not, run the helicopter for about 7 minutes (average tested flight time) and then charge it for about 45 minutes.
