Ebikes.ca/Ezee 48V Flat packs: Yea or Nay?

[IIIHorseman]

I was wondering what people thought of the 48V Flat packs that were available on the market. I was looking at the ones from BMSBattery and Ebikes.ca The Ezee version states that it uses Samsung Cells and has a good track record for reliability. I kind of like the idea of the Double Decker rack where I could still add cargo to the back; but was wondering if the key lock prevents the battery from being removed, or just turns on/off the motor.

Anyone have experience with them, and even post a picture of how the setup looks?

I used the 8Ah version of that battery for a year and it worked well.
As I recall, it delivered 7.5 Ah till the LVC shut it off, which was around 20 miles.
The things I liked about it were,
Very clean construction, flawless paint, sturdy rack[seat post], HD charger connector,
The 3 -way switch[lock, on-off] worked very well,
Although it took a while to charge[3 to 4 hr.s full charge @ 3 A], it was plug and forget. The charger would shut off and the batt. chem is safe, so I could plug it in and hit the sack. If I was in a hurry[rare], it would charge to 80% in an hour and a half[the BMS balance function takes as long again to top off].
It held it's speed thoughout it's discharge curve, but there was 2 to 3 volts sag on starts and hills in the bottom half of curve.
Dislikes,
The Anderson discharge lead is rather short[they do offer an extension]
I felt it was starting to lose a little capacity after a year of moderate usage, but was not able to confirm because,
All the cells died.
Not really the battery's fault though. I was working on an island in the Caribbean and when I left, the bike got stuck in a hot warehouse for a couple of months before it got shipped.

My thoughts after are,
Although somewhat pricey, it's a quality product that was right for me at the time.
But since I have been studying here for a while, I feel that I'm ready to give Lipo a try, so I wouldn't buy another.
But I like the box and rack so much, I'm thinking about trying to install some Lipo bricks inside and recycling those items[with the internal fuse and key switch]
And I'm also thinking about going with 13S Lipo so I can use the charger[54.6V hot]as a carry-on charger.

I've been running two of the 8 AH, 3C rated packs, in parallel, for probably two years now.
I'd like to have two of the newer 5C packs but these are still going strong.
After eating many, many, bad batteries from China, Justin settled on the Ezee packs because they are the most reliable.
You can't go wrong buying anything from ebikes.ca.

Anyone have an image what this looks like on the Bike?

The fact that Justin still sells them says a LOT. Some other vendors now offer only SLA.

But if you want longer range, you might want to look at pingbattery. I've been very happy with the two I've owned. 48v 15 ah is not too hard to find a hardshell box to carry it in. A bit more bulky, but not horribly awkward to carry, and can fit in many bikes triangle space.

Main advantage of the ping is it's just cheaper than a pair of Ezee batteries.
