Hello! I don't know where to post my concern about polymer lithium charger so I posted it here. I have seen and read about your polymer lithium battery description and like it. However, I want to know first about the charging precaution. Does a polymer lithium charger is also available in your store and what is the maximum hours when charging polymer lithium battery?

We have several different polymer lithium chargers available on our store front (see the product links below). The charging rate will be determined by how the board is configured, and will also be based on the number of cells in the battery (and you need to make sure you choose the correct charger to handle the number of cells in your battery).

I would recommend reading over some tutorials on batteries if you are unsure about this information before purchasing or attempting to use the lipo batteries/chargers.

Hopefully this helps clarify this for you.
