KX3 Please evaluate LiFePo4 battery/charger choice

[Arno Dienhart]

So I have decided to retire my heavyweight UPS battery and upgrade to a
LiFePo4 battery. This is what I am looking at:

 

Bioenno 12V/3Ah with PCM and charger

http://www.bioennopower.com/collections/12v-series-lifepo4-batteries/product
s/12v-3ah-lifepo4-battery

 

Am I expecting correctly that this should be plug & play?

 

I understand that more capacity will allow for longer operation, but I am
not planning for any marathon, and from what I have read, 3Ah should last
for several hours at 10W easily. Please correct me if I am off.

 

Thank you for your objective assessment.

Hi Arno,

The Bioenno 12V/3Ah LiFePo4 should work nicely with your KX3 and provide
several hours of 10W operation.

I use a similar 3.3 Ah from
http://www.batteryspace.com/lifepo4cellspacks.aspx and have been quite
satisfied with it.

Looks very good, Dave. I like the extra capacity and the 4S2P configuration,
and if they came with a PCM or if there were a reasonably priced balancing
charger, I'd have considered that product. But I could not find it.

 

How is this capacity working for you?

 

To add some information about the Bioenno PCM that I hadn't found
before.from their website somewhere:
