| LiIon and LiPoly batteries need much more respect than NiMhs or NiCds, the balance between constant current charging and then switch to constant voltage is vital, as is contantly managed an balanced discharging. This is what thyere is a safety circuit in the pack or the device it is powering.
Get it wrong and you do more than burst the cell, the Li can burn a building down. See the UN Transportation testing regulations. LiIon batteries are designated hazardous, in the same category as explosives.
Mobile chargers are designed to operate with the cells/ packs in the phones with constant feed back from the phone to the safety circutry in order to manage the process safely.
Motto is ALWAYS follow the manufacturer's guidelines and never split LiIon pack like you might with older technologies.
