thanks for the info-Stephen is correct-I transposed the number-indeed it is a 8955 charger/converter. also thanks for the install tip.
I have explored the websites for Victron and Progressive.  I will eventually talk with salespeople from both companies, but want to learn more first.
I assume the smart shunt must be installed in a protected and waterproof location .  this seems hard to do in a plastic battery box. so that is a big question.
Still learning.
Thanks

When I looked on Amazon it appears than the Victron smart shunt is about $130 and uses only Bluetooth to a phone app. The BMV712 is around $200 and has both an LCD display and bluetooth, so it seems like the Bluetooth only version without a display is cheaper. There's also a BMV700 for $140 with a display but no BT.

Here's a video link.

I had not heard of a 9855. Mine has an 8955 unit. Yes, you need to remove the two screws that hold the front on. That will then tip off and you will see the converter on the bottom half under the breakers and fuses. It is not too hard to change. The wires to the circuit board are the hardest ones as I had to remove the circuit board to be able to run the wires and get them plugged in correctly. It is held in by clipping into the panel with no screws holding it in place.

We would like to upgrade our battery charging system and are looking for suggestions. We boondock a lot and our power needs are moderate to low.  We are able to keep our batteries charged when traveling, but are looking to protect them and fully charge/equalize them when stored at home.

 

We currently have a 2015  model 179 RPod and have the stock WFCO 9855PEC charger.  We added 2 Trojan T-105 6volt golf cart batteries.  We use a Renogy 100 watt solar suitcase system with a Renogy pwm charge controller and also a Honda EU2200 generator. 

 

We are thinking about a Progressive Dynamics converter/charger and a Victron shunt and have just started researching both.  I know there are several options for both devices.

 

One question is which Victron unit to use-either the Smart Shunt or the Victron BV-712.  It seems that the difference is the Smart Shunt has a Bluetooth remote display for your phone whereas the BV-712 has the display adjacent to the battery or can be moved distant but has to be connected by wiring.  The Bluetooth is more expensive, but is it worth the extra cost?  Any suggestions, observations or other makes/models  to choose from would be appreciated.

 

When I open the Wafco converter, I don’t see the actual converter/charging unit, so I assume it is behind the fuse/breaker panel and located on the floor. How much trouble is it to change out the unit?? I recall several forum members doing this and would love to hear their ideas.  I assume that Progressive Dynamics makes a unit that is “plug and play” and a direct replacement. Is that correct? Any specifics I need to look out for?

Another question is whether the Charge Wizard is helpful or needed. From what I can tell from the website, it seems that the Charge Wizard basically tells you what charging cycle is occurring.  Are there other uses or benefits to this additional device?

 

Thanks in advance for any input.

 

Travel safe and often.
