Connecting battery to protoboard

I have been powering the protoboard using a 9V brick so far. Since I am trying to make an autonomous vechile, I need a method to power it that can be attached to the vehicle. I've been researching LiPo batteries and was wondering if there was a way to power the board from a different style connector. Or should I snip the connector off and solder on a connector from the brick? I know LiPos are more sensitive than other batteries so I'm just trying to avoid setting things on fire.

I have been looking at getting this, http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXVKS8&P=0·or something similar.

Thank you·for any help!

    Keep the brick intact to use in future and get another connector and cable to connect the protoboard to the battery. The connector is a common size so you can probably cut one from a bad wall wart or battery pack. It is a good idea to have the battery connected to a terminal strip and make connections to everything else from the terminal strip. Be aware that if your battery voltage is over 9V the 5V regulator on the protoboard will get hot and may shut down.

    PS - You should have a subject for your post. Something like "Connecting protoboard to battery".

    Are you using the servo header? On the robot that I built for OBC Contest I just solder it through the servo header. Just make sure you are using 9 volts or less.

    You can get good batteries at RC car shops (like Hobby people). You'll want to be able to disconnect your battery for charging and replacement, so a connector is a must. The Tamiya type connectors for batteries work pretty well. You could just replace or move the power jack.

    Edit: I think that battery that you linked to is a bit overpriced (for the power level). I got a 3300 mAH NIMH battery for about that price at my local RC shop. If you don't really need the weight reduction LiPO offers, then I'd go with the NIMH.

    LiPo's are good, I have been using them for years just handle them properly and charge them ONLY with a LiPo charger. Besides the weight reduction they have virtually no internal discharge so they stay charged for a long time. TowerHobbies does not have great prices . In Canada (?) check out www.rctoys.com or www.zebrahobby.ca. You should be able to get a better price (almost anywhere else).
