Even with the 25R battery the max run time will be no more then 30 - 40 minutes before the battery will likely cut out due to low voltage.

What ever you do please post a link to any battery before you buy so as not endanger your self or waste money, you have already done so with the kit.
Hi would this battery 100% work as on the voilamart website it says this(2nd screenshot)

The battery in the first pic is the one I have mentioned in #7 and the one I have spoken about at length in #18. It will get you the 10 miles and maybe up to 15-17 miles.
The voilamart message link is misleading as they/it DO NOT/DOES NOT mention anything about the battery discharge current required that needs to meet the continuous current possible, in your case you have shown the controller is 26a rated.

I have looked at several ebay 48v batteries and as usual none are suitable for higher power 26a continuous discharge, though most say they are for 1000w kits the kits they talk of will use a 20a max continuous controller .

In #2 & #3 both vfr and I have given sound advice to your required needs and I have extrapolated a little more in #18, continuous rating is what you need to look at and not just 1000w /48v this or that. Though 1000w/48v is important the continuous discharge current rating is the over riding main safety factor of most importance.

Thank I will purchase the #7 battery Also would I need to solder or can I use solder seal connectors to connect the battery to the controller?

Voilamart's are a continuing reoccurrence on here and on another thread Mike is still having issues with his set up, they are just cheap and nasty kits and buyers should do there homework first before buying.

You will need a charger also.

The #7 gives a charger with it 54.6V 2A CHARGER would this be good for the battery and how long will it take to charge roughly
4.5 hours max charge time from empty which would be about 42v.

HI I've spoken to voilamart and they said if I don't accept it they will give my full amount once they receive their product back what should I do?

If you can get a full refund then do so and re evaluate how much you can afford to spend on a kit including the battery.
For most kits with a less demanding controller of 15 -20a battery options open up more.

Sure I will decline at the door in the mean time I was thinking to but the woosh fx08c comes with kit and battery and charger plus a display

Post a pic of your bike and the type of use the bike is for and the terrain you travel, road, trails, flat or hilly and not being intrusive your approx. weight as it all has a bearing on what might suit best.

Is that your own bike or just a picture from the internet. if it's not yours, please post an actual photo of your bike if you want suitable advice. Also, we need to know how many gears you have at the back wheel.
