Looks very good for what you are using it for. Nice price tag too.
However if you do change over to LiPo, most will reccomend upgrading to a balance charger that can charge LiPo over 2.5 amps.
Since the Vision Peak Ultra is limited to 2.5 amp charge rate for LiPo's, it would only be good for charging a 2500mAh or less capacity battery. Most packs you run as a main LiPo pack will be more than 2500mAh and that charger won't keep up.
But since you only have NiMh type batteries, your good to go!!!
