Hi,
I have china e-bike "Zapp" (www.erider.cn), 2,5 kW / 60V engine and 19s
(40 Ah) LiFePO4, without BMS. Oryginal cells (from 2007) were made by
Thundersky.
After about a year of use, the 4 cells (from 19) were dead and I stop to
use e-bike.
Now I started to "repair" this e-bike. I order the "Active BMS" with 1,8
A max. balancing current (www.freegopower.com).
Next, I start to checking old cells and I found another 8 cells from
Thundersky looks dead.
I woudlike to buy new LiFePO4 cells but I have a problem - which china
company makes a bit better cells than Thundersky?
I check the china webpages and I found a few cheap offers:
- OSN Power (www.osnpower.com) - USD 48 for 66 Ah cell
- HAOYU ENERGY - (www.haoyupower.com) - USD 57 for 60 Ah cell
- A&S Power (www.aspowerbattery.cn) - USD 65,5 for 60 Ah cell
- LIAO - Hangzhou Liao Technology Co., Ltd.
(http://hzliao.en.made-in-china.com/) - USD 66 for 60 Ah cell
- GLB - GREEN LAND BATTERY (www.glbbattery.com) - USD 74 for 60 Ah cell
- Frey - Jiangsu FREY New Energy (http://www.chinafrey.com) - USD 74 for
60 Ah cell
Did anyone knows LiFePO4 batteries from these companies?
Any other tips or suggestions?
regards
Artur
