Over charge protection

by cheeguan on Sun Apr 24, 2016 1:30 am

Do the USB/DC/Solar lithium Ion/Polymer charger - v2 have a charge protection? As i do not want to over charge my battery and if I charge 2 lithium Ion/Polymer battery will the LED indicator for "Done" indicate for both battery or just one?

The charger cycle will end when the cell reaches the full-charge voltage (4.2v).

and if I charge 2 lithium Ion/Polymer battery ...

The charger can only charge one cell at a time.

Thanks for the reply but is there anyway to charge 2 battery in this module or there a other module that can support it? And is there a way to check if your module do support over charge protection?

Charging cells in parallel is not recommended unless they are part of a factory matched and balanced battery pack.
And is there a way to check if your module do support over charge protection?

As I said in my previous post. The charge cycle ends when the cell reaches full charge voltage. That is the definition of over-charge protection.

Iam trying to ask that is there a way to check if there a over charge protection on other adafruits module in their description or there is over charge protection for all the battery charging module as i would like to buy PowerBoost 1000 Charger - Rechargeable 5V Lipo USB Boost @ 1A - 1000C and VERTER 5V USB Buck-Boost - 500mA from 3V-5V / 1000ma from 5V-12V but i could not find in the description if it have the over charge protection......sorry iam still new to electronics.

All of our chargers have over-charge protection.
