Reasonable TalentCell LiFePo4

[Zermelo]

When I was researching batteries last year for a home-made power tank, the LiFePO4 chemistry seemed to be the most highly regarded and TalentCell was mentioned as a decent brand.

But the prices I found weren't compatible with my impecunious little project, so I got a lead-acid variety instead (only 7Ah, but it still weighs a lot, and needs topping up when not in use).

Recently I found this battery on the TalentCell Amazon shop:

The dimensions are OK (only a couple of mil wider than my lead-acid, same height and shorter length), and it was only £21.99 delivered, so I took a punt. I've used it and recharged it a couple of times, and so far, so good.

I realize that 6Ah might not be enough for heavier users, but it should be fine for me.
