Sixty-seven dollars. That’s the number on the Last Battery order button, and it’s the number most reviews focus on. But anyone who has ever started a DIY project knows the price of the instructions is rarely the price of the project.
That’s the angle of this review. Not just “is Last Battery good?” but “what will Last Battery actually cost you, and what are people complaining about?” Below is my honest assessment of the offer, a realistic cost breakdown for building what the guides teach, and a frank look at the complaints buyers are most likely to have.
Quick answer: Last Battery is a legitimate $67 digital guide bundle sold through ClickBank. A basic working backup setup will likely cost you a few hundred dollars more in parts, depending on what you already own. The main complaints center on the misleading name, the exaggerated bill-cancelling headline, and costs that aren’t made clear up front.

What You’re Actually Buying
Last Battery is a downloadable guide package from Big Moves DTS Inc. Based on product imagery and multiple reviews, it includes:
- The Battery Revival Guide, for testing and reconditioning old or weak batteries.
- The Watt-Stacking Tradecraft Manual, for planning household power needs and building a battery storage bank.
It’s digital-only. The official terms describe it as a book for informational and entertainment purposes, and they warn about chemical, electrical, and explosion hazards. The sales page itself is mostly a video, with a headline promising a veteran’s “anti-grid tradecraft” that cancels power bills.
The Real Cost of Last Battery
Here’s the breakdown most review pages skip. These are rough US ballpark ranges for a small, essentials-only backup setup. Prices vary widely by brand, size, and where you shop, so treat them as planning estimates, not quotes.
Cost 1: The guide
- $67, one-time, through ClickBank. Confirm at checkout.
Cost 2: Testing and safety tools
- Digital multimeter: roughly $15–$40.
- Safety glasses and chemical-resistant gloves: roughly $15–$30.
- Class-appropriate fire extinguisher: roughly $25–$50, if you don’t already have one.
Cost 3: Power conversion and charging
- Inverter, to turn battery power into household-style AC power. A small pure sine wave unit in the 300–1,000 watt range often runs roughly $60–$250.
- Battery charger or charge controller: roughly $40–$150, depending on type and whether you plan to add solar.
Cost 4: Wiring and protection
- Properly rated cables, lugs, connectors, fuses or breakers: roughly $40–$100 for a small setup.
- Battery box or ventilated enclosure: roughly $20–$60.
Cost 5: The batteries themselves
- Revived batteries: potentially free or low-cost if you can source old ones, though results vary and some won’t recover.
- New deep-cycle batteries, if revival doesn’t work out: often $100 or more each.
Realistic total
- Guide plus a basic starter setup: often somewhere around $250–$650, before batteries.
- With purchased batteries: add $100 or more per battery.
That’s still far cheaper than many commercial home battery systems. But it’s not $67, and buyers deserve to know that before ordering.
Last Battery Complaints: An Honest Rundown
These are the complaints that follow most naturally from how the offer is built. I’ve ranked them by how much they should matter to you.
1. The bill-cancelling headline overpromises
This is the biggest issue. Batteries store electricity. They don’t produce it. Without solar panels, or a time-of-use rate plan you can exploit, a battery bank won’t meaningfully reduce your bill. Charging and conversion losses can even add a small amount to it.
2. Hidden project costs
As the breakdown above shows, the guide is the cheapest part of the project. The sales page doesn’t prominently spell out what else you’ll need to buy.
3. The name suggests a physical product
“Last Battery” sounds like hardware. Buyers who skim can easily assume a battery will arrive in the mail.
4. Revival results are unpredictable
Some old batteries recover usable capacity. Many don’t. Swollen, leaking, cracked, or very old batteries should be recycled, not revived.
5. Time and effort
Testing, reconditioning, planning, and building take real hours, often spread across several weekends. It’s not a quick fix.
6. Limited verified feedback
As of October 2026, there’s little independently verifiable buyer feedback online. Many “real customer” claims on review pages are unsourced.
What Last Battery Gets Right
Fairness matters, so here’s the other side:
- Low entry price compared with commercial backup systems.
- Transferable skills for outages, RVs, cabins, boats, and future solar plans.
- Practical focus on essentials rather than unrealistic whole-home backup, judging by the reported contents.
- Clear risk disclosure in the publisher’s terms.
- Buyer protection through ClickBank checkout and its refund process.
👉 Check Current Pricing and Refund Terms
Is Last Battery Legit?
Yes. It’s a real product from a named publisher, Big Moves DTS Inc., with ClickBank handling payment and refunds. The legitimacy concern is the marketing, not the product’s existence.
Last Battery Bonus, OTOs and Bundle Deals
- Bundle deals: The $67 purchase reportedly includes both guides. I couldn’t confirm any multi-tier bundles.
- Last Battery bonus: Not confirmed from the sales page. Check the order page for anything included at the time you buy.
- Last Battery OTOs: One-time offers after checkout are common with ClickBank products but couldn’t be verified. Decide your budget before checkout so you’re not tempted by upsells you don’t need.
- Refund: A 60-day money-back guarantee is reportedly advertised. Keep your ClickBank receipt and order number.
How to Keep Your Costs Down
If you decide to go ahead, these steps will help you avoid overspending:
- Read both guides fully before buying a single part.
- Write down the exact devices you want to power during an outage, along with their wattage.
- Size your inverter to that list, not to an imagined whole-home setup.
- Test any old batteries you have before buying new ones.
- Buy safety gear first, and don’t skimp on fuses or properly rated wire.
- Start with one small system and expand only once it works.
- Have a licensed electrician involved before anything connects to household wiring.

Frequently Asked Questions
How much does Last Battery cost?
The guide is $67 one-time. Building a basic setup typically costs a few hundred dollars more in parts.
What parts will I need to buy?
Usually a multimeter, an inverter, a charger, properly rated wiring and fuses, an enclosure, safety gear, and batteries.
Can I save money by reviving batteries?
Sometimes. Revived batteries can reduce costs, but results vary and some batteries aren’t safe to revive.
What’s the most common Last Battery complaint?
The gap between the “cancel your power bills” headline and what battery storage can actually do.
Are there extra costs at checkout?
There may be optional upsells. None are required to use the core guides.
Is Last Battery a scam?
No. It’s a real product sold through ClickBank. The marketing is exaggerated.
How long does the project take?
Expect several sessions, often across a few weekends, depending on your experience and system size.
Can I get a refund?
A 60-day money-back guarantee is reportedly offered through ClickBank. Confirm the terms on the order page.
Is a portable power station cheaper overall?
Not always. Small units can cost similar to a DIY build, but they’re ready-made and certified. That makes them a simpler choice for many people.
My Honest Verdict
Looked at as a whole, Last Battery is an affordable guide wrapped in an expensive-sounding promise. The $67 buys you knowledge, not a working system. The full project will likely cost a few hundred dollars more, depending on what you own and how far you go. The complaints you’re most likely to have come from the marketing (the name and the bill-cancelling headline) and from costs the sales page doesn’t highlight.
For patient DIYers who want a practical outage backup and are comfortable with safety precautions, it can still be good value. That’s especially true with the reported refund window behind it. Just budget for the whole project, not just the guide.
Takeaways:
- The guide costs $67. The project usually costs more.
- Plan around a written list of essential devices.
- Expect modest bill impact unless you add solar.
- Prioritize safety equipment and proper fusing.
- Confirm price, refund terms, and upsells before paying.
