how to fit or where to buy from ??
Not familiar with the 960. Go for the LiFe @ 3.3V per cell (6.6V 2S) and try to get more than 1000mah, measure dimensions for the smaller unless they are completely different then it's two batteries.
LiPo will usually require a regulator to reduce voltage from 7.4 to 6V and it's just another thing to go wrong and more wiring. While I havent had problems, many have and it's not worth frying your electronics with too much voltage. In contrary, there are reports of drivers using a LiPo 7.4V without regulators, I personally wouldnt do it.
