New SOK 206ah reading 13,4 volts after charging?

Howdy All,
New SOK is reading 13.4-5 after first charge? is supposed to be 12.8, Wont LED Lights, fans, etc. in my van burn up at this voltage? any input would be appreciated.

13.4-5v is entirely normal for a charged LiFePO4 once charging is removed.

is supposed to be 12.8

12.8v is the nominal voltage; a form of technical shorthand. In this context is serves mainly to tell us

1. it is LiFePO4 chemistry
2. in 4S configuration (4x nominal 3.2v cells in series)
3. for 12v applications

Actual voltage can be as low as 10v (low voltage cutoff) and as high as 14.6v (often the high voltage cutoff).

Normal lead batts are nominal 12.0v but can charge in the high 14s and tend to rest fully charged around 12.7v.

No you'll be fine. 12 volt lights fans etc are designed to run in a range of voltages from the low to mid 14s to the low 10s. Many wider

Sorry for late response, was in sierra's, thanks for your support.
Maxx air fan has issues with voltages over 12, will be adding a regulator for the fan.

Mine has no issue running from lfp. Whether floating at 13.6v or absorb 14.1v. It's been over 6.5 years now.

Which model fan?
I see numerous complaints of this issue on google, youtube, amazon, etc.
Supposedly, they are updating their circuit boards at maxair also?
I have the 5100k model and don,t want to have to change the circuit boards out,
Like your 6.5 year status! Thats a good fan.

I believe the same as you.
