Nice to see a second Brushless XLB. Looks like a clean conversion. One year ago i too considered converting one, but spare parts were not easely accessible over here so i choose a truggy.

6s1p A123 seems to be a rather small battery config for this huge/heavy buggy. Depending on your driving style and gearing you might give those A123 cells a good workout and i would expect a rather low run time. With around 1500 Watt peak at your disposal (about 250W per A123 cell -> 100A@2.5V) your car should be very "driveable" on a track and not be overpowered.

This car should be able to carry 10-12 A123 cells with ease. If you ever feel the need for more runtime/power you might consider trying to run it with 5s2p A123 (3+2 cells humpback style, 3Vx5sx2090kv=31500rpm) or better with 6s2p A123 (3Vx6sx2090kv=37620rpm).

I opted using a Neu 1515/2Y (1100kv) with 10s1p or 11s1p A123 cells.
