Review: Surprisingly light, and does exactly what I wanted - I use this to run our electric cool box when we’re camping, and was very pleased that I could get so many amp-hours of capacity for the money. I’ve not had it long, so I can’t comment on its longevity but it’s nicely made, charges just fine, and is pleasantly light
Review: So much better than Lead Acid - I bought one of these to use with my Yaesu FT-891 Radio for portable use. I was sceptical at first. Performed a load of testing (I do this every time I buy new batteries) to push this battery to the limit. It performed flawlessly, in fact it out performs the specs. Really happy with the results and so much lighter to carry around in a rucksack. So happy I bought a second one. Just by these and leave the Lead Acid ones at home.

### ⭐⭐⭐⭐⭐ Excellent quality and value for low draw applications coupled with solar charger.
*by N***O on 17 September 2025*

I have this battery coupled with a 25w solar panel and MPPT charge controller to power my motion activated LED lights in my shed. It never seems to drop below 75% except 1 day when I spent most of the day in the shed and it was still at 25%. Highly recommended for low draw lighting tasks etc.
