I am currently looking at this battery: http://www.ebay.com/itm/DC-12V-1800mAh-Super-Rechargeable-Pack-Protable-Li-ion-Battery-EU-Plug-For-CCTV-/400940782911?hash=item5d59eed53f:g:mxwAAOSw5dNWj4Bn
I am going to use it for a slightly large robotics project where 12v is required for several sensors, 4 motors (2 in each output of an l298) and an arduino mega. Since the battery only has a male and femal dc jack (no regular wires) am I able to use this for the male jack to go into so I can plug into a breadboard?
I have used nimh batteries for my last project and the charge of them vary over time and from looking at many different lithium battery packs ive seen that some of them drop charge quite a lot, Is this true for all of them? The reason i am looking at li-ion is because from googling it seems the best choice out of nimh and li-po (cheaper and safer). Would you suggest this a good choice of power supply? (im on a tight budget too)
