@Al A few notes/corrections regarding my post: I mistakenly listed my wakespeed settings as CPF parameters...that was a mistake, so they are programmed correctly as CPB. I think you p...

Low Temperature Charging Prevented (Wakespeed 500+Cerbo+REC Q)posted in WS500 Tips, Tricks and support
Today I encounted a problem where the wakespeed would not charge under low temperature conditions. It appears that either the REC is sending a CAN message in error, or the Wakespeed is interp...

WS 500 + Dedicated Shunt + Cerbo + REC-Q = 2x DC Power Reportedposted in WS500 User Installation and Programming Questions
@Rick Admin Verified that the KW to the battery is correct with "DC System Off", but the battery KW was always correct. It was the DC Power reported in the DC block that was wrong.&nbs...

WS 500 + Dedicated Shunt + Cerbo + REC-Q = 2x DC Power Reportedposted in WS500 User Installation and Programming Questions
1. Values appear correct. E.g. REC reports 142.8A while WS reports 151.6A (which is correct based on the DC Loads running). 2. Gonna hold off on trying that. 3. I'll try this and repo...

WS 500 + Dedicated Shunt + Cerbo + REC-Q = 2x DC Power Reportedposted in WS500 User Installation and Programming Questions
I recently installed a dedicated shunt for my 24V Alternator/Wakespeed charging source (CAN connected to Cerbo and BMS). This is on a system with a REC BMS that provides its own battery current dat...

How to manage state of charge while on shore powerposted in REC Active BMS
You can use the generator start/stop functions associated with relay 1 on the Cerbo to \"gate\" or modify the charge enable signals from the REC BMS (assuming the REC active has charge enable simil...

My Documentation of Wakespeed Configuration and Testingposted in WS500 Tips, Tricks and support
Thats only for if it loses CAN communication/BMS is not working (super conservative - might change it). Otherwise, it\'s charging is directed by the REC BMS.

My Documentation of Wakespeed Configuration and Testingposted in WS500 Tips, Tricks and support
I finally got around to documenting my config and testing which may be of use to other. For background my system is a 560HA 24V LFP built from EVE 280 cells with a REC-Q BMS. The Wakespeed is con...

Van Harness connector Typesposted in WS500 Tips, Tricks and support
Just got around to looking at this connector in person (as I was about to pin the mating connector). The info wakespeed provided was only partially correct: The Field/Stator connector is a DT06-2...

Van Cable lengthposted in WS500 User Installation and Programming Questions
On my van harness, I measured my alternator lines (temp sense and field/stator) to be 27 ft from the wakespeed harness connection to the alternator connection. The ignition wire was similar. All ...

Daughter card to add second amps inputposted in WS500 Improvement Suggestions
Can you elaborate or do you have this documented anywhere? How did you communicate these values to the WS500? I\'ve been kicking around a similar idea and replacing the REC BMS shunt data (slow) ...

Van Harness connector Typesposted in WS500 Tips, Tricks and support
From Wakespeed: 1. The connector used on the Field/Stator wires at the alternator is a Deutsch DTM04-02. They are available through Digikey, Mouser, or most other electrical suppliers (I’ve also s...

REC and WS500 CAN-based battery current stabilityposted in WS500 Tips, Tricks and support
I\'ve come across information here and there that suggests the WS500 can use REC provided current via CAN. However, the WS500 documentation says \"Note: If instability is seen with Current Regulat...

REC Q incorrect (high) Voltage sense on most positive cell (Cell 8)posted in REC Q Series BMS
@tine @rick_tech_support any issue with using something as low as 56 Ohm? I have a bunch laying around and was going to use them?

REC Q incorrect (high) Voltage sense on most positive cell (Cell 8)posted in REC Q Series BMS
@rick_tech_support, thanks! Primoz at REC got back to me in the meantime with a suggestion that fixed the issue. Essentially the resistances on the \"battery simulator\" were too high. @tine, ...

REC Q incorrect (high) Voltage sense on most positive cell (Cell 8)posted in REC Q Series BMS
Hi, I recently received my REC Q from you guys. Looks great! I\'m in the process of testing it in advance of installing it on my cells. I\'m seeing a voltage sensing anomaly on what would be c...
