Hi Guys,
Sorry if this is a duplicate post - i've been searching the net & forums for an answer on whether it's safe to do the following.


Crude diagram

Smart Charger <-----> Battery (105Ah 12vdc) <---> RB2011

I'd like to run an RB2011 directly off a 105Ah deep cycle battery that will be connected to a smart charger.
My country is experiencing prolonged load shedding, so we get +- 6 hours of grid power a day.
The RB2011 includes a GPON ONU.

I've seen a guide on youtube for a RB1100 that used a DC-DC converter - but in this case they were connecting via a power pack, not via battery direct.

Can anyone provide advice on this? I would really appreciate it - thanks!

The Routerboards have a wide power supply tolerance. The RB2011 has a 8-30 Vdc input specification so a 12v battery even with a charger is fine.

Just be sure to include an appropriate fuse between the battery and RB ... 105Ah is awfully lots of energy to let run through RB after some shirt curcuit ...

A fuse rated at approximately 2.5A should be fine.
