Kayendedwe kakayendedwe kake kamatengera kutulutsa kwapadera. Batire yomwe idavotera mizungu 2000 pa 0.5C imatha kukwanitsa mizungu 1000 yokha pa 2C. Factor discharge behant to the total cost of umwini kuwerengetsera-batire yotsika mtengo yomwe ikuwonongeka kuwirikiza kawiri yomwe imawononga nthawi yayitali{7}}.

Kwa mabatire a lithiamu a 24V mumagetsi adzuwa kapena osunga mphamvu, 0.3-0.5C kutulutsa kosalekeza kumayendetsa katundu wambiri wapanyumba bwino. Zida zazikulu monga zoziziritsira mpweya zimatha kukankhira zofuna ku 1C mwachidule. Kuyika mphamvu 2-3x katundu wanu wapakati kumapereka chiwongolero cha kutulutsa uku ndikukulitsa moyo wozungulira kudzera mumayendedwe osaya.

Zitsimikizo zachitetezo ndi mtundu wa BMS ndizofunikira kwambiri pamene mitengo yotulutsa imakwera. -Mapulogalamu apamwamba amafunikira chitetezo champhamvu ku-panopa,{3}}kutentha kwambiri, ndi mayendedwe afupiafupi. Opanga okhazikika omwe amaika ndalama pamapangidwe oyenera a BMS amapereka zinthu zotetezeka kuposa njira zina za bajeti, makamaka mabatire omwe amagwira ntchito pamwamba pa 1C pafupipafupi.

Kutulutsa kwa batire kumayimira mawonekedwe ofunikira a batri omwe amatsimikizira ngati batire ikuyenera kugwiritsa ntchito pulogalamu yanu komanso kuti ikhala nthawi yayitali bwanji modalirika. Kumvetsetsa kugwirizana pakati pa C-tilingo, panopa, mphamvu, ndi kagwiridwe ka ntchito kumathandizira kusankha bwino batire, kamangidwe kabwino ka makina, ndi moyo wa batri wokulirapo. Kaya mukugwiritsa ntchito foni yam'manja kapena galimoto yamagetsi, kufananiza zomwe zimafunikira kuti zitheke kutengera mphamvu ya batri zimatsimikizira kuti zikuyenda bwino, zikugwira ntchito moyenera komanso kubweza kopindulitsa pa batire yanu.
