What makes a LifePo4 battery specific to an RV?
Sorry if this sounds flippant or snarky but I've had a couple adult beverages.... so ... here it goes...
Design? Intended application? Name?
I'm going to go out on a limb here and say... If it has an On/Off switch, it wasn't intended to be used in an "automotive" application.
au·to·mo·tive
adjective
1.relating to or concerned with motor vehicles.
Logic tells me that a server rack battery is designed to be in a server rack. A server rack typically resides in a server room. A server room is typically in a data center. I'd venture to say that the BMS was designed to be coupled with a large number of other BMS's(?) to support multiple high frequency inverters to provide uninterrupted power to delicate electronics in the event of a power outage... Little to no surge, no vibration, controlled climate, etc.
My application has huge surges, lots of vibration, and extreme temperatures. I applaud SignatureSolar for their efforts to make these "energy storage devices" do what they weren't designed to do.
I bought the EG4 server rack batteries because I was looking for the best bang for the buck ($3.75 per AH). If I wanted plug-and-play, "grab some jumper cables and welding rods and let's get this rig back on the trail", I would have filed for divorce and paid $8.80 per AH for BattleBorn and made my Inverter/Charger the weak link... but I didn't.
EG4 makes a "WP" battery that is designed to be used in a motor vehicle. If you buy 4 of them, you'll get 400ah at 12v at a cost of $2200 ($5.50 per AH) and have a combined BMS capability of 400 amps when run in parallel. I'd be willing to bet 16 of them would easily start my inverter, but $8800 and all the space and cable to connect them was not desirable to me.
SOK has an amazing product but, purely for self preservation, they don't even offer a 12v server rack battery.
I could go on and on but, I digress...
... sorry again :-(
