Good charger for li-ion batteries?

[mobile1]

Can anyone recommend a good charger for li-ion battery packs?

Will be charging 4 cells in series.

Thank you for your help.

You can buy an individual charger for $2.00

Use 4 separate power supplies and 4 separate chargers.

The problem you will run into with charging batteries in series is 'balance'
You have no guarantee that they will charge evenly, and you can quite easily damage one or more of the cells if they become unbalanced and either over charge or over discharge.
The simplest solution is charging them separately, the more complicated solution is looking to buy a charger designed to charge and balance 4 cells, or to build one yourself.
What kind of experience do you have?
