Buddy! We are live with meshing between my pi5 and OPENManet. The final bit of info I found was setting BATMAN routing algorithm to match OPENManet which is running V instead of IV. Additional steps to join mesh were:
batctl ra BATMAN_V # set routing algo to V instead of IV
batctl if add wlan1 # adds wlan1 to batman and creates bat0
ip link set bat0 up
ip addr add 10.41.x.x/16 # match OPENManet subnet
OPENManet verify
root@BCM2711-2067:~# batctl n
[B.A.T.M.A.N. adv 2024.3-openwrt-6, MainIF/MAC: wlan0/11:22:33:44:55:66 (bat0/11:22:33:44:55:66 BATMAN_V)]
Neighbor last-seen speed IF
11:22:33:44:55:66 0.420s ( 7.1) [ wlan0]
Pi5 verify
root@pi5-halow-1:~# batctl n
[B.A.T.M.A.N. adv 2025.5-1-g35208d12, MainIF/MAC: wlan1/11:22:33:44:55:66 (bat0/11:22:33:44:55:66 BATMAN_V)]
IF Neighbor last-seen
11:22:33:44:55:66 1.492s ( 7.1) [ wlan1]
I will now proceed with some field testing for range. I need to order another seeedstudio hat so I can actually have 3 node and testing mesh routing 
I got the wpa_supplicant format from OPENManet and it works well on the pi5. I got all the opclass and channel matchups for easy switching of the wpa_supplicant_s1g file after you make a change on OPENManet.
| Channel Width | Channels |
|---|---|
| 1 Mhz | 3 - 39 (increments of 2) |
| op_class=68 | |
| s1g_prim_chwidth=0 | |
| s1g_prim_1mhz_chan_index=0 | |
| [u] | |
| 2 Mhz[/u] | 6 - 46 (increments of 4) |
| op_class=69 | |
| s1g_prim_chwidth=0 | |
| s1g_prim_1mhz_chan_index=0 | |
| 4 Mhz | 8 / 16 / 24 / 32 / 40 / 48 |
| op_class=70 | |
| s1g_prim_chwidth=1 | |
| s1g_prim_1mhz_chan_index=1 | |
| 8 Mhz | 12 / 28 / 44 |
| op_class=71 | |
| s1g_prim_chwidth=1 | |
| s1g_prim_1mhz_chan_index=3 |
Final script I used
Final working script. I did not look in to further optimization of the wpa_supplicant_s1g parameters and instead stuck with what worked after copying from OPENManet

About 20 feet of separation with no obstructions. Both devices on external battery and ever so slightly under powered.
