Bob,
Thank you, thank you for your interest in my LTO project. I'm a retired airline pilot interested in RVs. I was shocked at the absolute garbage peddled for product in the RV industry - invariably 10lbs of shit crammed into a 7lb bag -totally unable to survive in real-world temperature extremes (It was 128 F in the desert outside Las Vegas a couple of weeks ago and Montana winters routinely produce cold snaps to -20 F). The RV industry's solution is to shut down the product when it cannot handle real-world temperatures so the owner loses the use of his investment for several months per year - ridiculous.
I decided to try for something better. My target from weather bureau data to handle 98% of temperature extremes in the Americas and Europe is -20 F to +130F. I've produced a shell with state-of-the-art insulation on a frame strong enough to handle the constant pounding of unimproved roads.
120V/30A AC and 13.8 VDC electrics start with as much battery capacity I can engineer into the available space, presently implemented with 150 Yinlong LTO prismatic 30AH cells. Perfect Switch has provided the BMS. Delagreen Power contracted for the balancers. Balancer prototypes were noisy but worked fine. But the entire order was bad and had to be returned. Right now my balancer selection is up for grabs. Delagreen will be offered the opportunity to fix their product while I consider alternatives. Very few companies make LTO balancers. I've looked at the Orion but it cannot handle my configuration (
