52v 20ah will be good with that hub drive kit.

48v 20ah would be alright and a bit cheaper.

As long as you charge the batteries right, and just treat them easy, like dont discharge all the way then recharge as soon as ya get off the bike....
don't just charge it in your living room and walk to the grocery store...don't drop or hit the battery..
I'd think you should be ok. Also look into ebike battery bags to charge in. Here is a link to read through:

Looks good as long as you're ok with low amp hours.

Looks good as long as you're ok with low amp hours.

What does the low amp hours do? Will it make the battery power not last as long or will it affect the overall performance of the bike?

The more AH the more saddle time you'll have.
For instance, a 48v 17.5ah battery might get you 40 miles per charge, while a 52v 45ah battery will have you in the saddle for about 80+ miles.
Depending on your riding style and terrain.

All in all the more the ah the more time on the bike you get.

If I had to go back to those style of battery i'd go with at least 20ah.... if I could find one of those @25ah i'd snatch it up
if it was from a good battery builder.

Don't forget to reach out to them and send them emails with questions concerning their batteries and or if they can make one to your specs.

 

[Dno007]

So would a 48v 17ah be better for longer journeys?

 

[Dno007]

Who are good battery suppliers ? Guessing the ones on ebay are no good , ? Ive been looking at this one too the 48v 17ah or 48v 20ah

Well, they mention certification, but they also use "weasel words"

• Certified by ISO9001 , and most batteries have UN38.3 ,MSDS, CE, ROHS certification

"Most?"

Always ask whose cells they are using in their battery packs. Use Samsung, LG or Sony. Stay away from no name Chinese cells.
