E-Bike batteries….. which one ?

I’ve had good service and support from UPP. Unit pack Power.
Don’t always believe the mfr/brand battery the supplier claims to use in your unit.

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

Usually default to the one with the more Ah, however take some claims with a grain of salt, for instance in my opinion there is no way a 13s3p is going to have 20 Ah and beware of the cells the cheaper"grade A cells are probably not as good as Panasonic or LG cells, honestly I figure around 2.5 to 3Ah per row( paralell) never been disappointed and yes17 Ah should quite easily make a 15 mile round trip especially if you help it out I do a 16 mile hilly rough loop with a 15 Ah battery with a 500 watt geared motor and have plenty of juice to spare when I get home.Looks like you have a DD motor on the "Great Pumpkin" ( orange and black), if so you can use the correct controller and display(KT) and get regen,save a few watts and really save on brakes
If it was Me I would go with the 17Ah battery.

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

Yes, and realize that Sony cells are Murata. (Sony bought Murata, to have a battery company under its umbrella) There are a couple others that we use in power tools that are also good, but not nearly in as widespread use as the three above. (Samsung & LG seem to be the most popular)

48 volt battery is a good choice, as is 17 ah battery. You will have plenty of juice from that battery for a 15 mile round trip…I expect you could go 35-50 miles on it depending on the power setting you use. 48 volt batteries have been around for at least 3 years and have a good reputation for ebike use.
you should expect to pay $500 - $700 for a quality battery with 17ah. Any higher ah is a waste of money for your needs, imho.
