Kad smo vec kod Li-Ion baterija,zanima me da li moze nesto da se nadje kod nas,da bih video sta da uzimam od uredjaja?
Zanima me da li u Srbiji,mogu da se nadju Li-Ion celije koje nose oznaku 18650 (IZGLEDA kao AA baterija),ili mozda 103450 (koja je samo pljosnata poput baterije na mobilnom
),naravno voltaza je 3,6-3,7v.
Inace se obe vrste koriste kao celije u baterijama za notebook racunare.Ja bi ih koristio za pravljanje beck-up baterije za prenosne uredjaje,na toj(3,7),duploj(7,4),troduploj(11,1) ili cetvoroduploj(14,8) voltazi,ili eventualnu zamenu starih dotrajalih baterija,videcu jos.
Cena celija krece od 5 dolara do 14-15 dolara za neke kvalitetnije KINEZE,a Panasonic
i Sanyo sto bih bilo pozeljnije nigde nisam video u prodaji(na malo).
Evo i par slika kako bih vam pojednostavio,sta me zanima,i nekih specifikacija.

These fully protected cells simplify usage with their integrated PCB. Perfect for your single cell application these cells are not for pack building as doing so will defeat the PCB protection which is matched to the correct voltage on a single cell. If you are building a pack please choose one of our other cells and the appropriate PCB.

NOTE: Use special caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. We are not responsible for damage if there is any modification of the batteries/chargers in any form or shape (including pack making). We are not responsible for any damage caused by misuse or mishandling of Li-Ion batteries and chargers. We only recommend using Lithium Ion rechargeable batteries with a control circuit (protection PCB) to assure safe charge, discharge, etc, use of lithium ion batteries with a protection circuit is potentially hazardous
Nadam se da ce mi neko pomoci da ih nadjem! Hvala!
