Delivered today in good order. Not tested yet, so I can write about my experience in ten years and hopefully not much sooner. My only regret is that when I ordered after logging in, the VIP member discount disappeared and the price went up even more, and finally the price was reduced even more, so it cost me almost $100 more to order two pieces.
Came with +80%SoC. Accuracy of BMS is not too high, at least from the very beginning. I charged just a couple of Ah and it said 100%(13,5V). But I charged another almost 100Ah on top of that and now with around 13,8V it looks like it is really full. Handles are very convenient for 31kg unit that can easily be carried around. Performance specs are really good enough to get even car charging done without issues. Connectors are solid, so far so good... Shipment was very fast, 4 days only. Packaging ist OK, those units are robust.
