I just finished testing my batteries with a load tester, and all 6 of them were over 40 Ah. Going with XS Power for LTO batteries is worth the extra money since you know that they pass their quality control. I would much rather buy XS Power’s LTO batteries than trust a third party seller for cheaper ones since I have heard many stories of Grade B cells being sold as having 40 Ah capacity. You really do get what you pay for. I am very happy with my purchase and I will be ordering 3 more sets for my build.
