You are correct in suggesting that you are hitting LVC... the prop may be too big ...but that would apply only if your load current is exceeding ~10A (the motor's limit). More likely the battery is not up to the task and its voltage under load is dropping too far. As you found out using a bigger battery helped the situation. I'm assuming your LVC is set at around 7v = 0.9v/cell. There are decent NiMh packs which should easily maintain >1v/cell under max. load. What is your current draw when the LVC kicks in? What physical size are your NiMh cells?
