Be informed and knowledgeable about charging batteries
More free [and useful] information from all-battery... see link in right-hand margin... is yours for the asking with their weekly emails.
Check out some more of the information sent in this weeks offering [in quotes]...
How fast can I charge a Li-Polymer pack?
Each Lithium Polymer battery pack has a different maximum charge rate. It is very important to never ever charge at a rating above the specified rate! Most batteries have a label that specifies this vital information. However, if the maximum charge rate is not specified, keep in mind that most Lipos are made to be charged at a rate of 1C. Which means a 1000 mAh pack can be charged at 1A and a 500mAh pack can be charged at 0.5A. Once again, never ever exceed the maximum charge rate lest the battery explodes!
If you need to, or want to, know --- now you have the answer!

"What is Lithium Polymer C rating?
A lot of radio-control fliers quickly grasp the meaning of most of the battery-associated acronyms but one: the C rating. In fact, many experts have tripped over themselves trying to explain it. However, I've heard a graspable explanation of it from an old Chinese battery manufacturer/expert very recently. Which is: The 'C Rating' is the number which you multiply to the capacity of the battery to get its discharge rate.
Still confused? Basically, a 1000 mAh battery rated at 1C will provide 1000 mA of power for 1 hour. On the other hand, if the same pack was rated at 2C, it would provide 2000 mA of power for 30 minutes."

'Weekly Tips' from All-Battery
The following is one of the useful 'Weekly Tips' which all-battery send in their really informative and helpful emails.
I must admit I have learnt a great deal from these useful tips... read on to check out the free information on offer this time...
"What is Li-PO Cell Balancing?
Lithium Polymer batteries usually come packaged as a pack of more than two individual battery cells. For example, electric RC helicopters use 3-cell packs. Each of these battery cells has a nominal voltage of 3.7v; which means that each cell can operate when it maintains its charge between 3.0 to 4.2v. To go above or below or below this range can damage the cell and render it useless, or worse, become dangerously unstable and explode.
While the battery is in usage, the power drawn out of each cell is not equal. Therefore, at the end of each flight, the cells in the battery will be left out of balance. A non-balancing charger will stop charging the battery pack once the voltage of the overall pack is full - without paying any attention to each cell. This causes the battery to be more and more unbalanced with each charge and would also result in a diminished performance of the battery pack.
A balance charger eliminates any unbalanced-cells symptoms of a battery pack by charging each cell individually; making sure that the cell's voltage remain balanced at the end of each charge. In essence, balance chargers lengthen the life of the battery back, and maximizes its performance, as well as keeping the pack stable and safe to operate."
