wow thx guys. very much appreciated
Jenny's batteries have Samsung 50E or Samsung 35E cells in them. Top of the line. For my own battery I was able to verify everything looks well made, battery pack looks solid. I've ridden it in rough trails and wet conditions without issue.btw, I like Jenny's 25ah battery but had an early failure on my NCM Moscow stock battery, just barely out of warranty with extremely little usage. so my concern is reliability of these batteries. I'm not sure who makes NCM batteries and cells used? I am leaning to having 2 batteries for safety and to eliminate potential loss of ebike availability. Also maybe better warranties would help. 1 year warranties seems low for Canadian climate with maybe 6 months recreational usage. Do you know of any companies having longer warranties on these batteries.
Hi Explorer-1, Jenny's 25ah has its place, but I had a bad experience with my NCM stock battery...with less than 20 charge cycles, very little usage but just over 13 months of ownership the battery failed. Leon Cycle was firm on their 12 month warranty, so from my experience these batteries can fail. so better to have 2 batteries...cut my losses. I am pretty sure it was a weak connection to start with, that caused the premature failure of my pretty new NCM battery...so buying a 25ah is risky...big loss if internal failure.
Also my rides are not usually that long. so 25ah is added weight when not needed.
and most important, is if you only have 1 battery and it fails, like what happened to me on a trip... you are out of luck. until you can get a new one.
Sometimes bigger is not better.
I agree, I think I said as much in my previous message. Seeing as how you already have a battery I was still recommending the 25Ah as a second battery so you had the choice of 1 25Ah battery on your trip, your existing battery on your trip, or 2 batteries for a very long trip. I carry 2-4 batteries typically 2 on one bike and 3 on another. I have 5 batteries for 1 bike and 4 for another. With a large battery for one bike though I can do decent trips on 1 battery, but i typically carry a second minimum even if I don't plan on needing it, I often change my mind, and like you say in the event of a failure.Hi Explorer-1, Jenny's 25ah has its place, but I had a bad experience with my NCM stock battery...with less than 20 charge cycles, very little usage but just over 13 months of ownership the battery failed.

Also one of my bikes has a pretty significant performance drop as the battery depletes another reason I like multiple batteries, and I never want a bike that uses 2 batteries at one, I want to switch from the 1 battery to the other for better battery maintenance and more control in general of my charge cycles.
Yes, that is going to be the case very often as the larger capacity batteries often spread the load across more cells so the drain per cell is less which can result in a much better discharge curve. This is why some of the very small packs are actually not a good idea, even when built with extremely high discharge cells not typically used in ebikes, you are stressing the battery a lot more in use. Of course there are exceptions because different cells are used in different batteries and sometimes the extra capacity is just a different cell, and sometimes it may be an additional cell to each parallel stack (13 for the 48V pack) or it may be both a cell change and a increase in the cell count. It's too bad every battery pack is not legally required to disclose which cell is used, I think for safety reasons and just full disclosure of specifications this should be required.My son and I have identical bikes and a 13ah, 16ah and 25ah battery. We've found that's one of the other unexpected bonuses of having the 25ah battery. Both batteries deplete and lose some of their performance as the batteries die, but the 25ah has a MUCH better curve with its higher capacity. Down in the 46v and below volt range the 16ah is more sluggish and the voltage gets pulled down a great deal on the hills, but the 25ah with its deeper capacity has more useful energy in those voltage ranges and doesn't wane on the hills nearly as much.
