Valence XP Super Thread

Yeah £500 each is way over the top but hey they are yours to do with as you wish , I got mine on eBay at a very keen £90 a battery I bought 10 , I wish I’d have bought more but I wasn’t sure if they would be useful at the time of purchase.
Are yours the u27-36xp batteries ? Fancy putting up a picture or two ?
Really wish I could find the u27-36xpd for £90 each at the moment. :)
 
Yeah , I’ve just bought 6 more from eBay , had to pay more for those , £800 so £133 each which is still cheap given what they are capable of . The 6 I’ve just purchased actually originated from the same place but passed through a few peoples hands after so I’m glad the batteries are the same age and I think they’ll perform the same as my original 10 .
 
Hi All,

I have 4 XP27s in parallel at my cabin with solar charging and generator if needed. Lately they get down to 12.9v in morning before sun hits. Are they being hurt by this?

A bit late but no, their safe cutoff discharge voltage is 10.0V - so oodles of room... I would not have thought they are even half discaharged at 12.9V...

Forgive me but I do not want to read through this entire (enormous) thread but would be interested in a *cheap* ('ish) solution to the issue of monitoring a bunch of U27-12XPs all at once rather than having to do them one at a time via the Valence diagnostic app...
Anyone got any links to something, please?
