Anyone have any information or rumors on an AVINOX 900+wh battery?

same. the cells weight 1g more. 40 cells... so i would say the same.

The availability is the problem. Molicell wanted to deliver the cells in september last year...
and now the date is moved month for month

avinox is not discharging to 2,5V so they don't use the full capacity, but the Cell last longer. (good).

a 10s4p config would mean 40 cells. that would be 936Wh max in the datasheet. a little bit unter 900Wh in reality


there are other cells with 6,6Ah aviable, but they can't handle the load in turbo.

I think is ~3g more per cell so 40 * 3 = ~120g heavier than the current FS800 battery

I have the new 700wh and have held it side by side with the 800. It’s pretty incredible how much lighter it feels in hand and how slim it is. Idk the numbers, should have weighed them, but sold the bike that had the 800.

Problem with the 700Wh (beside 700Wh), is the formfactor. It is super long.
can't take one extra in the backpack

Avinox compared to my old Bosch..

Not really, weight difference with wh equalized is minimal: FS700 3.18kg at purely theoretical 800wh would be 3.63kg vs 3.74kg of the FS800, 110g not that much difference.

The only real advantage is the slim tube with the issue that 700wh is the only capacity doable with this cells.
The problem with the cells of the FS700 is that you can only create a 700wh or 1400wh that would be twice the length or twice the width both not practical for an emtb.

Unless they for the next generation Amflow bike decide to create a slightly thicker version of the Ampace 50480 cell.

Just a slight cca 4mm increase in diameter would raise the capacity to cca 80Wh. Total pack capacity would then be cca 800Wh.
The con would be decreased cooling properties as the heat would have a longer path to reach the outside and cca 400g higher weight, so cca 3,6kg.

Just for an example,to reach cca 90Wh cell capacity(pack cca 900Wh) they would need to increase the diameter to cca 57mm so a 7mm increase, that's a measly 3,5mm on every side, I doubt that that difference would be visible with the naked eye from a distance. The con again cooling properties and a cca 700g weight increase bringing us to 3,9kg for the pack.

A slight increase of the downtube diameter isn't that hard when developing at their pace I guess. The only question is, is there enough market demand for large batteries like the 900Wh, I guess that the main driver of development.
