What are your loading conditions? Do you have a model number for the motor so that we might be able to better understand? Are you using the batteries that we used for competition or are these some other chemistry (NiCd, Li-ion)? are these batteries in series, parallel, or individually connected to the motors?
Why are you only able to obtain half power? How are you gearing this drive train? wheel size? wheel traction? In general, depending on the loading condition, the power your motor demands is not a static number
Will it burn up? Well that depends a lot on the motors thermal constants (casing, efficiency, etc) and it's ability to handle a stall current among other things
More information is required to give you a good answer.
