BionX Lithium Battery technical information

We all know that the Bionx weak part is the battery.. as well as on many ebike on the market.

I decided to make my own research about the BionX Lithium ion battery.



Here is what i found:

BIONX LiMn BATTERY specs:

- Battery voltage: 37V nominal 41-42V fresh of the charger

- Capacity: 9.6Ah ( 355.2Wh )

- Cell arrangement: 10s6p

- Battery BMS: NO balancing.. But will cut at 31V

- Cell model: 18650V from Sony (SE US 18650 V)

- Cell capacity: 1.6Ah 3.7V

- Cell format: 18650 ( 18mm dia x 65.0mm long)

- Cell max current ( 16A... 10C)

- Pack geometry: 60 Cells tied together 12 cell long of 5 cells wide

- 60 cell pack manufacture: BMZ (Batterien-Montage-Zentrum) in Karlstein tél +49618899560 http://www.bmz-gmbh.eu
But their factory burned entirely in 2008: Now i dont know who took the relay for that...


- REPLACEMENT CELL SOURCE: MAKITA BL1830 3Ah 18V pack contain 10 cells

- temp monitoring via a temp sensor on the battery cut at 90 celsius

- Max pack charge current ; 1.6A (18.0 A cells can handle.. not the BionX battery)

- Max discharge current: 18.0 A

- Charge temp condition : 0 to 45 degrees

- Discharge temp condition : -20 to + 60 degrés

-Finally a project for converting BionX to A123: http://ruthnlarry.net/evs/bikes/solrh/a123intro.htm
