I’m just about to pull the plug on a 4 cell Alibaba purchase and I think I’ve figured out how to manage the issues.
The two known good suppliers I’ve contacted are Amy Wan at Luyuang and Selena Li at Xuba.
Ms Wan was formerly at Xuba and has left to start her own company. Ms Li is her successor at Xuba.
Acceptable quality cells are limited now. Luyuang only has grade A Eve new at $122 and Xuba has Rept, a new manufacturer, at $89. Reading a bit into things Lishen has established their reputation and is no longer selling to this channel. CATL may have more quality issues.
I trust both Luyuang and Xuba to manage quality issues and the lack of acceptable grade B cells is likely due the large numbers of competitors that are NOT able to manage those quality issues.
REPT still needs to establish their reputation, but I believe Xuba can manage that - including balancing cells at a reasonable cost.
The thing I’ve added to this DIYSolar method is insuring that I can inspect for shipping damage prior to receipt. The younger Ms Li was not able to help figure this out, so I’m going with Luyuang.
I was going to get the overkill solar BMS, but instead I think I’ll get the $20 Daly. I will still need to get the Victron Temperature sensor, but my Victron system will also provide the charge and load info via their Bluetooth app.
To build a box/compress I am planning on using plywood and threaded rod. I’ll also add some PKYS blue sea doodads.
Does this sound good? Any additional suggestions?
PS, I have received a number of Alibaba inquiries from suppliers making pre packaged batteries. If I hadn’t figured out the rest I might have considered. Under $1k for 280 ah. The sturdier 100ah Fortune cells in a 200ah 2p4s configuration would also be a good choice.
This market will continue to evolve, let’s do our best to keep this channel open by being known good customers.
