why does this battery not have the specific feature of "Battery includes built-in protection against over voltage, over current, and minimum voltage." that the 1100 mAh and 100 mAh batteries do?

That's a good question. The 2000mAh battery has the same protections listed in the Safety Test section of the data sheet as the 100, 860 and 1100mAh batteries.

Does this battery have a inbuilt overcharge/overcurrent/discharge protection pcb like the other li-ion batteries or not?

Hi I very elementary question: Does this then mean that I can charge my battery, with a Li-Po charger of course, with a 5V mini-USB wallwart that came with my cell phone? Thanks

yes you can charge these batteries on usb power But use the correct charger or you will be calling the fire dept. this one will work LiPoly Charger - Single Cell 3.7-7V Input https://www.sparkfun.com/commerce/product_info.php?products_id=726

Hi That is the charger I own; I bought it when I bought the batery. What I'm curious about is whether or not a 5v cellphone charger plugged into the mini-USB on the li-po charger is appropriate? Thanks Christian

(That is the charger I own; I bought it when I bought the battery. What I'm curious about is whether or not a 5v cellphone charger plugged into the mini-USB on the li-po charger is appropriate?) yes you can Motorola chargers are cheap and plentiful As long as it has mini-usb connector on it

Quick question, i plugged this into the logomatic v2 and i cannot seem to get it out. How do you unplug this type of connector? Thank you

	by N8B \| Jul 1, 2010 at 2:18pm
I usually use needle nose pliers. I grip on the sides of the connector not the top and bottom. There is no locking mechanism or crimp or anything like that, yank it and it will come out.

i guess it took a lot more force than i thought, Thanks.

Hello - Do you know if I can use the iPhone USB charger to recharge this battery? Many thanks!

	by N8B \| Jul 29, 2010 at 2:17pm
If it explodes then no. Most cell phones it seems like use 3.7V LiPos. Mine does anyways. Try it and find out...maybe wear safety glasses while you do.
