Shipment takes a long time, but this was to be expected for this product. The first test with a 30A discharge current went well (little bit under 100Ah). The capacity meter does not show quite a realistic value, but I understand it well because the voltage is not a linear for capacity range.
CAUTION - WARNING! The capacity of the Lifepo4 battery rated 100Ah is only 86Ah, when measured according to seller procedure (I am an electrical Engineer). Also the battery arrived totally empty at cut off voltage, while it was shipped 80% loaded (according to seller). Probably one cell is bad. Seller request for evidence a video of several hours lenght, fotos not accepted. Return shipping would be extremely expensive if not impossible for dangerous good. Seller does not agree to reduce to the price of the 80Ah version. 2.5 months from order to arrival. I don't recommend at all this battery provider, seems this is second quality. There are plenty of reliable good manufacturers and sellers even from China today, who provide the first quality batteries with the correct capacity rating. I bought dozens of them and had no defect even after years of use, only with this manufacturer and seller - watch out.
