Large Capacity Polymer Battery Charging Problem.

2 identical 10AH polymer battery cell without protective plate in series, if the charge current is 1A, the charging voltage is constant voltage 8.2V, if the battery is still charging for a long time, the battery will not overcharge, because a single battery The charging voltage of less than 4.2V should be safe voltage, even if full of still charging, there will be no overcharge problem, right? Will the battery have any adverse effects?

Answer:

Any battery is fully charged do not continue to charge, if there is no protection line, there is no protection board, so the battery will burst bulging explosion. It is recommended to update the smart charger, it will automatically detect and timely stop
Voltage is not a problem, the key is current
As you do, do not tell more, but there is no protection circuit is very dangerous, it is recommended to get a
