FAQs
Frequently Asked Questions
Common questions about battery chemistry, solar storage, ordering, and technical support.
What battery types does BatteryLux cover?
Lithium-ion, LiFePO4, NiMH, AGM, sealed lead-acid, and deep-cycle marine packs — plus guidance on solar inverters and home energy storage sizing.
How do I choose between lithium-ion and LiFePO4?
LiFePO4 typically offers better cycle life and thermal stability for golf carts and solar storage; lithium-ion often wins on energy density for compact packs. Share your duty cycle and we will recommend.
Can you help with solar + battery system sizing?
Yes. Use our blog guides on panel count, hybrid inverters, and 10kW home systems — or send load, autonomy days, and location details for a quote discussion.
What details do you need for a quote?
Voltage, capacity (Ah or Wh), chemistry preference, pack size/form factor, quantity, destination, and application. Datasheets or competitor SKUs speed things up.
Do you ship internationally?
Yes. Lead times and shipping terms depend on chemistry (air restrictions may apply for lithium) and order size. We coordinate logistics with compliant carriers.
