Lipoly Balancer?

       Remove this ad - become a site supporter!
What is the purpose of a balancer? I have a hobbico mark 2 charger and would I benifit from having a balancer? I'm still new to this electric thing so any help would be greatly appreciated.

Well, in a battery pack after dozens and dozens of charge & discharge cycles the individual cells get to a point where they are not all at equal voltages. In the case of NiMh or NiCd batteries this was not that critical and was dealt with by discharging and recharging at low amperage settings repeatedly. This could be done manually with your model motor or a bank of light bulbs or automated using a device known as a "Cycler" . Some chargers have this capability, such as the "Triton".

In the case case of "Lithium Ion" or "Lithium Polymer" or their sibling "Lithium Whatever" (there's more and more variations on that theme all the time). You could do the same thing but really you want to avoid using up the batteries usefull life Cycles on this boring process. So you plug a "Balancer" between the charger and the Battery pack when ever you find a measurable difference in the individual cell voltages over about 0.1 volt.

The "Balancer" can work in two ways, it can work by cutting off the charger to each cell as it reaches its maximum charge voltage or after a pack has been charged it can place a small load on any cell with a voltage that is higher than the lowest cell in the pack. Either way your battery gets back in balance and you avoid the danger of over discharging a low cell or over charging a high cell. The danger with Lithium cells is FIRE, they don't like being either over charged or discharged. They can break down chemicaly, heat up and combust in either case.

Hope this helps.

Moe explained it well.

There's lots of ballancers on the market although I went with the KISS approach myself and got a Astroflight "blinky".

Find it here at effective.

There's more glorious options on the market but in the end they all accomplish the same thing, and few can boast a price tag of $29.
