Check your owner's manual and make sure your XL5 speed control has a "low voltage cutoff". If so you can safely run Lipo batteries. If not stick with Nimh batteries until you upgrade to an ESC with Lipo cutoff or low-voltage cutoff.
Lipos have several advantages that make them well worth the extra cost.
1. You can charge them with no "cool-down time" You can put a lipo back on your charger as soon as you finish a race. A typical 5000mah lipo will only take 15 to 20 minutes to recharge after a 5 minute race. That means you only need one lipo for racing.
2. Lipos hold a charge much longer than nicads or nimhs. A lipo you charged last week is still fully charged.
3. Lipos are much lighter than Nimhs cells for better power to weight ratios.
4. But the best advantage is their ability to push large amounts of amps. That typical (and inexpensive) 5000mah 25c 2s lipo pack will provide 125 amps continuous. A typical Nimh is hard pressed to provide more than 30-40 amps peak. Amps = Torque, Torque = excelleration.
