When it comes to recharging a LiPo battery, do I really need a special charger? I have this battery: Polymer Lithium Ion Battery - 1000mAh - SparkFun Electronics
It comes with a built-in Protection Circuit Board; cut-off circuits that prevent over-charging (above 4.2V) and over-discharging (below 3.2V).
So the question is, if I hook this up to a 5V @ 500mA rail, shouldn't the built-in PCB prevent over charging (and thus a catastrophic fire)?
Second question is about wiring two of them up in series to get 7.4V setup.
I know I can get 2Cell PCB and remove the current PCBs (sorta like this one: Rechargeable Batteries & Battery Chargers - PCB for 7.2V Li-PO and Li-ion 18650 / 18500 7.2V battery packs (7A Limit)-PCB7.2V7A ). The 2-Cell PCB should be able to balance the current in both cells and perform the same over-charge/over-discharge protection for each cell. So do I still need a special 2Cell charger? or can I just hook the setup to a 5V@500mA rail?
Thanks.
