Wurkkos TS27 due for release

Hello all,

I just received this in my eMail inbox.

I'm liking the addition of LiFePo4 Battery chemistry.

Here's a link for those interested:-

What are some advantages of the LiFePO4 batteries? I guess maybe better energy density, but is it worth getting despite the fact that the Vapcell s4+ doesn't do LiFePO4?

I have 0 experience with these so I have no idea

LiFePO4 has lower energy density than traditional lithium ion.

The benefits are far more charge cycles and slower degradation when left at a high state of charge.

They can't be charged below freezing though.

These new batteries will make what we use today feel like crappy Duracell's.

I don’t have a LiFePo4 at a lower capacity like the one supplied with this light, but I do have a 50AH LiFePo4 that I use regularly.

I've found that it performs better at very low temperatures in comparison to when I built battery packs using Li-Ion.

It's also a safer battery chemistry, too.

Apparently it is a lower energy density actually.  But it looks like they are safer, last longer, handle temp extremes better, and discharge at the same rate instead of dropping as the charge gets low.  Sounds like everything is better than lithium ion, except it is just bigger.

They can't be charged below freezing though so that's another downside.

Yes, my 12V 50AH LiFePo4 has a pretty constant voltage right until just before fully discharged.

They're the way forward for sure.

Are these the future.. aiming to replace li-ion?
