FAQ
Q: Lithium lama inthlak tur hian kan charging infrastructure tihdanglam a ngai dawn em?
A: A tlangpuiin a ni, mahse lei duhtu tam zawkin an beisei aia tlem zawk. Lithium charger hi lead-acid tlukpui aiin a te zawk a, charging room bik mamawh ai chuan hnathawhna hmun bulah wall-bun theih a ni. Infrastructure zawhna dik tak chu electrical capacity a ni: lithium pack tam tak a ruala fast-charge hian amperage nasa tak a la chhuak a ni. Quotation tin nen site assessment checklist kan dah tel a; circuit limitation hriat hmasak hian a hnua change order a pumpelh thei.
Q: OEM lead-acid chu lithium hmanga thlak hian kan stacker warranty a titawp em?
A: Hei hi siamtu hrang hrangah a inang lo. Toyota, Crown, leh Raymond te hian lithium option emaw approved third-party program emaw an pe vek a ni. Brand dang tan chuan warranty terms uluk takin enfiah la, a tam zawk chuan voltage leh mounting specification OEM mamawh nena inmil phawt chuan battery thlak hi chiang takin an phalsak a ni. Kan walkie stacker battery te hian standard lead-acid form factors nena inmil plug-and-play design an hmang a; stacker brand lian ber berte tan compatibility documentation kan pe a, order i commit hmain fitment kan confirm thei bawk.
Q: Engtin nge finance emaw leadership emaw atana upfront cost sang zawk hi ka justify theih ang?
A: Leina man aiin darkar khata -operating-hour man angin frame rawh. I quote number tak tak hmang la-industry average-ah innghat suh. Kan 24V 280Ah LiFePO4 pack hi baseline atan: cycle khatah darkar 6 chhunga cycle 4,000 kan neih chuan darkar 24,000 a thawk thei. I quoted price chu chu number nen chuan zatve rawh. Lead-acid nen khaikhin la: a tlangpuiin darkar 4 chhunga cycle 1,200 (accounting for real-world capacity fade) hian darkar 4,800 a pe chhuak thin. Tichuan, kar khatah battery khatah minute 20-30 vel maintenance labor dah belh tur a ni. Kan TCO worksheet hian he tehkhin thu hi i input data nen a siam chhuak nghal vek a ni.
