How To Build a Portable Camping Battery For Under $130

You’ve got your camping setup dialed in, and you want to extend the weekend to milk a little more out of your trip. But you also want to charge your phone, run your 12V Fridge overnight, light up your camp, and bang out a little work on your laptop so your boss doesn’t get testy while you’re out...

Anyone built one of these in the UK?

I'm thinking of making one for my van.

Using a lipo car starter battery thingy as the basis.

240/ 12v Charger and possibly an inverter.

Just to run lights phones cool box etc.

Cheers James

I would be EXTREMELY cautious about messing around with LiPo batteries unless you know what you are doing. They do NOT like being mistreated in any way and have a tendency to start bulging and deforming if they are.

I think that's just a lead acid...

There's quite a lot of DIY battery building websites and YouTube channels about. They focus on LiFePo batteries, which are much safer than Li-Ion.

I'll probably just use a starter battery pack like this

And see how long a 2a cool box lasts on it!

Any guesses?

Not very long! I doubt very much if it is 89Ah capacity, as advertised.

You won’t be able to do that.

Even the smallest B2B I know of which is 30amp is three times more than a cigarette lighter will take.

Or this?

Sterling Battery-Battery Maintainer 12V-12V, 3A

The Sterling B2B Maintainer diverts a small current from a charging source to a second battery, preventing self-discharge & extending battery service life.

The Victron maybe if you can turn it down to 9 amps.

The Sterling no, it isn’t designed for that.
