Frequently Asked Questions

Can I drop off a dead battery?

Yes — we recycle dead batteries free of charge. Just bring it in. We accept all lead-based batteries: automotive, marine, RV, mobility scooters, and more. See our battery recycling page for details.

What does the "24/72" warranty mean?

Our 24/72 warranty means 24 months free replacement and 72 months prorated. If your battery fails within 24 months, we replace it at no cost. Between 24 and 72 months, you pay a prorated portion based on remaining warranty life.

Do you install solar panels?

We don't do rooftop panel installation, but we can help you with everything else — hardware, components, system design, and walking through the steps to do it yourself. We stock panels, charge controllers, inverters, and all the wiring components.

Is solar worth it? What are the pros and cons?

It depends on your situation. We've put together a detailed comparison guide at Lithium vs. Lead that covers the trade-offs. For off-grid applications, solar + lithium is almost always the right call.

Do you help with on-grid (utility-tied) solar?

For grid-tied systems, we recommend connecting with the professionals at Solar Energy Design. Our focus is off-grid, portable, RV, and battery storage systems.

Why should I choose lithium over lead?

Lithium (LiFePO4) batteries have significant advantages over traditional lead-acid:

• –Weight: roughly 1/3 the weight of equivalent lead-acid
• –Efficiency: usable capacity is ~95% vs ~50% for lead
• –Bluetooth BMS: monitor cells, state of charge, and health in real-time from your phone
• –Zero maintenance: no watering, no equalization charges
• –Longevity: 3,000–6,000+ cycles vs ~300–500 for lead

How long will a lithium battery last?

LiFePO4 batteries typically last 3,000–6,000 charge cycles to 80% of original capacity. For most users charging once a day, that's 8–16 years of service life. Compare that to 3–5 years for a typical lead-acid under similar use.

How do I reset the BMS?

See our BMS Manuals page for step-by-step guides for both the JK BMS and Xiaoxiang BMS units. If you're still stuck, give us a call — we're happy to walk you through it.
