1.For our 40Ah 2.3V LTO battery, please kindly note that their difference are mainly focus on capacity, voltage, internal resistance, K value, etc for between A grade and B grade cells. And both our Grade A and grade B cells have the same high power rate for folklift application. Here attached the comparision chart for your reference so that you would check easily.
2.A grade has standard parameter upon full specifciation with 3 years factory warranty, applied for high power train system in electrical vehicle, long service life in energy pack system, government PV/solar energy system. B grade has lower capaicty, lower voltage and lower performance without any warranty, which is mainly for 12V~48V low votlage system, car audio, static energy pack system, etc.
3.B grade performance is not always stable.
4.A grade products are manufactured in full accordance with product specifications,Each battery has been rigorously tested and fully complies with all parameters
5.LTO A grade cells have circle life 25,000 times,
6.From the cost view, B grade is good for car audio or solar energy pack, however B grade has no warranty and has lower performance.In long term view, we suggest A grade for stable and consistency performance.
7.A grade has standard parameter upon full specifciation with 3 years factory warranty, applied for Yes for long term business and warranty for end users, we also suggest customer to use A grade
8.Each our cells has original Yinlong barcode, which would able to trace the real cells condition upon Yinlong data base, you can check with Yinlong factory or ask Alibaba to involve for investigation. And you will know that all our cells A/B standard are 100% the same as Yinlong factory
9.For batch order we can provide full datasheet for each A grade cells.
10.All our LTO are A-grade,so it's going to be more expensive than B-grade,the quality can be guaranteed.
