Battery Balancer (LiPo Battery)

Well pampered battery can increase Heli performance and longer life span!
A Battery Balancer can "Level" each cell's voltage difference. To understand how it works, you need to know what is Li-Po Battery Pack. Li-Po Battery is made from Li-Polymer Cells, they were all manufactured to have standard 3.7V on each cell, when they are linked together, they form a Battery Pack, like 7.4V, 11.1V, 14.8V or 22.2V, as you can see, they are all multiple of 3.7V.

Why you need a Battery Balancer?
When you buy a new battery pack, it has stand 3.7V on each cell, after fully charged, each cell usually has 4.2V-4.3V, after a flight, they usally becomes around 3.5V-3.6V. However, every cell has a little bit difference on discharge rate and capacity, after a period of time, you get different readings on each cell, this is normal. To restore the battery to former glory, we use a Battery Balancer to "Level" each cells to the same voltage, then we use a Balance Charger to fully charge it, and the battery lives again!
