He aha ka nui a me ke kaumaha o nā ʻeke hāmeʻa cordless i loaʻa?

	ʻO ke ʻano o ka chemistry, voltage, battery capacity, a me ka ʻenehana i hoʻohana ʻia e ka mea hana hana e pili ana i ka nui a me ke kaumaha o nā ʻeke no nā mea hana uila ʻole a me kā lākou mau mea hana mana.
	ʻOi aku ka nui o ka pilahi uila a me ka hiki ke hoʻonui i ka nui a me ke kaumaha o ka pākaukau, ʻoiai hiki i nā ʻenehana hou ke hoʻemi i ka nui a me ke kaumaha, e ʻae ana i nā pā liʻiliʻi e like me ka ikaika a paʻa.
	Ma waena o nā mea kemika ʻekolu i loaʻa, ʻo nā pākahi nickel-cadmium ka nui a me ke kaumaha. Ma ka ʻaoʻao ʻē aʻe, loaʻa iā lākou nā mea maikaʻi ma mua o nā mea ʻē aʻe e hiki ke uku i ke kaumaha (e nānā. He aha ke ʻano o nā pila no nā mea hana mana?)
	ʻO nā pākahi Lithium-ion ka mea liʻiliʻi loa a me ka māmā. ʻO ka pākaukau lithium-ion ka hapalua o ka nui o ka pākahi nickel-cadmium o ka mana like a me ka volta, a ʻoi aku ka māmā ʻelima. He pōmaikaʻi nui kēia, akā hiki mai ia ma ke kumukūʻai o ka ʻoi aku ka palupalu.
	ʻOi aku ka māmā o nā pila NiMH ma mua o nā ʻōhua NiCd. Ma ke kaumaha like me ka pākaukau NiCd like, hiki i kahi pākahiko NiMH ke loaʻa ma kahi o 30% ʻoi aku ka nui.
	Aia nā mea a pau i ke koho ʻana i ka mea hana pono no ka hana. No ka laʻana, inā ʻoe e hoʻohana ana i kāu mea paahana i kēlā me kēia lā e hoʻoponopono i nā mea hana paona liʻiliʻi e like me ka lāʻau, hiki paha iā ʻoe ke noʻonoʻo i nā mea paahana a me nā pihi me ka uila uila a me ka nui o ka hiki (e laʻa me 18V 2Ah pākahiko). no laila hiki iā ʻoe ke hoʻokō pono i ka hana, akā me ka luhi ʻole o kona kaumaha.
	Pono ka nui a me ke kaumaha o ka ʻauʻau aila 500 gram, ʻoiai ʻo kekahi mau pā lithium-ion hiki ke kaumaha ma kahi o 180 grams.
	Aia kekahi mau mea paahana liʻiliʻi a māmā ma ka mākeke i kēia lā, i hoʻohana ʻia e nā pākaukau liʻiliʻi hiki ke hoʻouka hou ʻia. He kūpono lākou no nā hana DIY maʻalahi e like me ka wili ʻana i nā papa insulating a me nā lua wili e kau ai i nā kiʻi.
	ʻO nā pākahi lithium-ion e hoʻohana ana i kēia mau mea hana, ʻo ia ka liʻiliʻi liʻiliʻi o nā ʻāpana uila i loaʻa. Ma 7.2V a me 1Ah, he 80g wale nō ko lākou kaumaha.
	Ma ka ʻaoʻao ʻē aʻe, loaʻa nā mea hana mana cordless no nā hana hana metala kaumaha. Pono lākou i nā pila me ka volta a hiki i 36 V a me ka mana o 5 Ah. Hiki i kēia mau pila ke like ka nui o ka pahu margarine 1-kilogram a hiki i ka 1.3 kg ke kaumaha, ʻoiai hiki i nā ʻenehana hou ke hoʻemi i ko lākou kaumaha i hoʻokahi kilokani.
	ʻO ka mea hope loa, he nui kāu koho e pili ana i ka nui a me ke kaumaha o kāu pā uila uila uila. Hiki i nā mea hana a i ʻole kāu mea hoʻolako ke hāʻawi iā ʻoe i nā ʻōlelo aʻo hou aʻe e pili ana i ke koho ʻana i ka mea hana maikaʻi loa no kāu hana.
