Last Battery review
A DIY battery guide that claims it can wipe out your electricity bill

Is it worth it?
The bill lands, it's up again, and the standing charge alone is starting to feel like rent. That's usually where people find this one. Last Battery is sold through a video with a big promise on top: a Vietnam veteran's 'anti-grid' method that cancels your power bills. That's the seller's claim, and the page offers nothing to back it up. No photos of a finished build, no parts list, no before and after bills, no numbers at all. Worth being straight about the physics, because a physical result is what's being sold. Storing enough electricity to run a house isn't a trick someone is hiding from you. It's cells, an inverter, wiring and a charge source, and those cost what they cost. A home built pack can genuinely keep a fridge cold through an outage, or keep phones and lights going, which is a useful thing to own. Cancelling a bill outright is a different order of claim, and nothing on the page supports it. So the fair way to buy this is as a cheap set of ideas for backup power, not as a way out of the utility. If you already tinker with 12V gear, you'll probably pull something from it. If you're hoping to stop paying, or you'd be nervous stripping wire, spend the money elsewhere. Also note it bills you again, which is odd for what looks like a one off guide.
Pros
- Costs a tiny fraction of any quoted home battery install
- Backup power for a fridge and lights is a real, achievable goal
- Video format, nothing to wade through
- Scratches the itch if you already like building things
Cons
- The bill cancelling claim is asserted, never evidenced
- Everything is hidden behind a video, so you buy blind on price and contents
- It's a recurring charge, not a one off payment
- No mention of what the actual parts will cost you on top
What you get
Honest answer: the page doesn't say. It's a video with no written rundown, no contents list, no sample chapter. Going by how things like this are normally sold, expect a digital guide or video walkthrough you download and work through yourself, plus whatever the recurring charge covers each month. You won't see a parts list, a cost estimate or any specs until after you've paid.
Before you buy
- Open the Terms link and find the refund window plus exactly how to cancel the repeat billing
- Add up what your fridge, lights and phones really draw, so you can sanity check any of this against your own house
- Assume anything tied into your home circuits needs a qualified electrician, and budget for that
Who it suits
