Bok!
Novi sam na ovom forumu stoga mi oprostite ako nešto krivo pitam ili konstatiram. Zanima me koja bi to cijena bila prihvatljiva za bateriju od 48 V Li-polymer i o kojim strujama pražnjenja govorimo kad se upotrebljavaju na e-vozilima?
Na raspolaganju imam ćlanke koji su kapaciteta i dimenzija :
6Ah 5X 103 X 122 mm 126 g
8,6Ah 7 X 103 X 122 mm 175 g
15Ah 7 X 150 X 245 mm 460 g
30Ah 15 X 150 X 245mm 1000g

Ovi ćlanci su dobavljivi u roku od 10 do 30 dana ovisno o zauzeću proizvodnje. Proizvođać nudi i izradu baterijskog sklopa i punjača .
Trenutno imam baterijske sklopove od 7,4 V i 11.1 V 2100Mah 25C ali oni su u vjerojatno preskupi za uporabu na e-vozilima.

Dobro dosao Shadow! Smile

Ako mislis na e-bicikle, maksimale struje su od 20-40A
Napon od 36-72V

Reci ti nama cijenu ako vec nudis.. Very Happy ..i mali oglasi imaju svoj podforum Very Happy ..a komercijalni svoju cijenu hehe Wink

Imaju li protection circuitry (overcharge 4,2V/cell, overdischarge 2,5V/cell, overcurrent 10C?)...
Maksimalne struje praznjenja i punjenja?

I, jos jedna hipotetska rasprava...
...paket 8.6Ah x 2 x 15 tj. 17.2Ah/55.5V - kakav bi mogao biti odnos kapaciteta u odnosu na GreenSaver bateriju 48Vx10Ah pri maksimalnim prakticno dozvoljenim praznjenjima (17,2A za prvu odnosno 20A za drugu)?
