That kit appears to not have the variable PAS levels. Some of the cheaper kits like mine the PAS is set to max amps meaning its like having full throttle on a gas engine all the time. This makes the PAS function basically useless so I rely on the throttle. While its not the end of the world, PAS is one of the main points of ebikes and allow you to free up your hands for brakes or the gas throttle. If the kit has a LCD display it usually has the different PAS levels . So, I would really think about that and see how that fits into your needs. I imagine that this might be okay for you. Going up a hill, I imagine you would open the electric throttle and then the gas throttle. But, you can get the different level PAS function for $50 more and if you ever need it.
For the battery, I am skeptical of those that don't list any of the specifications of the battery pack or manufacturer. I have seen two type of lithium ion batteries out there for ebikes, the regular grade and high discharge rated batteries. The regular grade suffer from a nasty drop of in capacity with high amp draw, but are cheap. I have a 36V 17.6Ah 600Wh pack for $200 and I generally do not draw high amps except on hills.
AH is amp hour and a measure of capacity. Most people use watt hour (Wh) to normalize battery capacities. Power or watt (W) is determined by voltage(V) * amps(A). The BMS on a battery pack determines the amps that you can draw. Check that number and multiply by your voltage.
I think the questions you need to ask are
1. Do you want a variable PAS system? This will let you pedal and power the electric motor at the same time.
2. Are you only using the electric motor for hills? If so, you might not need that strong of a battery pack and can go with lower grade lithium ion battery pack.
3. Got to find out the rated and maximum discharge amps (A) for the battery pack when buying. This will tell you how much power you can draw.
4. Got to find out the type of lithium cells making up the pack. Low grade isnt bad if you are using it only on hills but if you want to really go all out on the power then higher discharge rated cells might be needed.
