Due to the inability to modify the option image during the event, the 300AH model is currently no longer available for shipment. Orders will default to the 314Ah version for shipment. If you have any questions, please feel free to contact customer service"

Will Prowse did a review of the 300ah. I think the only major thing against it was it doesn't have over current protection but if you run a reliable fuse or circuit breaker it shouldn't be an issue. It looks like half of the large old casing was full of foam. Makes a lot more sense once you watch this. I'm contemplating upgrading to this from my 100ah since I now have an ebike I want to charge off solar from my van.

Update, it looks like the BMS is bad on the battery I received. I am hoping the return/exchange will not be too difficult. The Discharge Overtemperature Alert is showing and the T1 sensor is showing 221F, and has not moved. The battery is not hot at all so it's more than likely a bad sensor/BMS. The MOS sensor is showing under 60F which appears to be accurate.
Oh well... This was my first attempt ordering with Aliexpress. I guess this is not surprising.
Still not a bad price, but they lied about the upgrade.
Sorry, but I have to give a thumbs down for this.
