Ɔkwan bɛn so na hokwan a wɔde bɔ lithium batere ho ka no yɛ adwuma?- Polinovel .

Hokwan a wode bɛbɔ wo ho ban no kyerɛ sɛ wode lithium batere bɛhyɛ mu bere a woregye w’ahome no sen sɛ wobɛyɛ nsu a ɛyɛ adwuma yiye-charge cycle. Battery no tra lɔre no mu. Operators to top it off bere biara a wɔmfa mfiri no nni dwuma-awia, shift nsakrae, twɛn wɔ trailer so. SOC floats wɔ 40-70% range no mu da mũ nyinaa.

Na lead-acid eyi sɛe battery no. sulfation a efi charging fã bi mu. Lithium nni saa ɔhaw no. LFP cells no ankasa kyɛ bere a wode sie mid-range.

Here’s the thing about lead-acid a nnipa a wonni adwuma no mu no nkyerɛ anisɔ koraa: charge logistics yɛ dae bɔne.

A lead-acid pack ma counterbalance forklift kɛse bi mu duru yɛ nkaribo 2,500, ɛtɔ mmere bi a ɛboro saa.
