BATTERY UPGRADE

[RJC]

If it's also a 48V pack, the only difference in "performance" I would expect is longer range -- maybe 50% more?

That's what i'm hoping for.

keep us updated!

It's Great. 48v 20ah Battery now fitted. Much improved range from the original 13 ah one. Covered the first 22 miles on PAS 4 on the flat before the first battery level bar dropped. That's nearly twice as further than the original before level bar dropped.
Came in just over two weeks which I thought was pretty quick.

The range has improved again after charging the battery for the second time. Now at 30+ miles before first level bar on the display goes out. Mainly on PAS 4/5 with some miles on level 6, also set on Power Mode. Happy with that................

Not necessarily.

Not all 48V are made same because of amperage.
I'm talking about A, not Ah.

For example, my original battery was 48V 10.4Ah powered by Samsung 26F, then I switched to 48V 14Ah powered by Samsung 35E.

Although the 35E isn't the top of the line battery by any means, it gave me a very noticeable difference in terms of performance, because of increased amperage.
I'm talking about increased current drain of electricity, burst rate, etc. Not the capacity (Ah)

Are you talking about the NCM bikes? I thought the controller was limited to 750W @ 15A.

Did you pay import duties?

No duties paid

 

[-sandro-]

Yeah sorry my bad, I meant 720W.

I see, the ones sold in the EU have a 15A controller that you can unlock since it comes shipped at around 10A. I forgot that in the US the limits are different.
It's rated at 250W but you can unlock it to 350W nominal.

Hi, on the Moscow they fit the same as the standard battery. I think the largest amp rated one may have a greater depth but the length is the same. Not sure on the Venice but I would expect it to fit straight in.

I'm seeing 21ah batteries everywhere now, I'd like the range, but the price? $1200 is a lot of cabbage! I've seen them as high as 27.2ah on Alibaba, for a whole lot less, but am leery of buying... They most certainly won't be Nickel Cobalt Manganese polymer.

I would need a reention Dorado format like the one pictured here:

reention Dorado

Seems to me the Reention frame case is limited 70 cells-18650

I haven't personally used or seen the inside build.

Is the Dorado case one of these?

It is listed at over 6kg so I believe they've made the case taller to accommodate more batteries while still fitting the mount...

 

[tomjasz]

Timpo or, does anyone know which Reention case is being used in this case?

Kirin_Kunshan Reention Mechanical and Electrical Co., Ltd.

 

[-sandro-]

No it's the Dorado case.
The problem with these is what kind of cells they use? I doubt NCM chemistry.

Here's a capture from their ad...

they're the purple ones, I agree most won't be using ncm as their lithium polymer...

Aren't the venerable Panasonic PF cells LiNiMnCoO2?

 

[-sandro-]

Don't know, I don't even know what brand is used inside the original batter pack

The NCR18650PF's chemistry is LiNiCOMnO2, I'm not sure that's what they're using in these aftermarket cases. As I stated in an earlier response, one of the industry pics shows purple wrapped cells, I don't know their origin or composition, there's a high incidence of counterfeit clones in China...

 

[tomjasz]

Any good source will reveal which cell they are using OR will build to your requested cells.

Here is one listed at $650Cdn w free shipping. No idea of what cells they use.
