Hi Will,
My Class C RV solar installation is in-progress. I have been following in Geriakt's footsteps, but using all Victron equipment (MultiPlus 24/3000/70, Smart MPPT 150/45, Orion 24/12-70, and a Orion 12/24-15 DC-DC for charging from chassis) and 800 watts of rigid solar all installed and ready for intended 2 x 24V Tesla S. batteries. Currently have 2 x 12V 62Ah FLA battery that came with the rig. I have an electronic engineering degree and experience, (but not in solar power) and understand the tech aspects of your (mildly) anti-Tesla reasoning. However there are. two major advantages:
1. Cost - Battleborn, etc. are about $.75/Wh, "kit"-style LiFePO4 storage is about $.50/Wh, and a Tesla 18650 pack is about $.25/Wh. My physical design goal is to run the RV air conditioner at night, thus need about 10kWh. Tesla battery cost will be about $2400, and scale upwards (x2 or x3) for the other battery cost groups.
2. Density - Geriakt has basically the same RV model as mine. His decision to mount the two ~3x12x26" inch Tesla batteries in the pre-existing RV battery box (7.5x13x27") keeps from using up any additional valuable storage space.
Geriakt is using an ElectroDacus SBMS0 for each battery. Do you have any comments about this BMS or consider any others for Tesla installations?
Any LiFePO4 installation requires due care for weather and temperature control. Of course warranty and replacement availability are also considerations.
Other than name brand batteries, what would you suggest?
