Product Specifications:
8 cells in series in each module.
Gray and Black modules are identical but mirrored. Gray modules have the positive on the Left, Black modules have positive on the Right. If you plan on running batteries in series side by side, you would need matching colors. By default we will ship all identical position, if you would like to specify which modules or a mix of the two please contact us.
These modules were used in their solar storage application for a total of 3 months before being removed and traded for a larger system. There is a sticker on the module behind the BMS that indicates the date of manufacture as 2021.11.09. We have capacity tested several modules and found them to be above the rated 67Ah, some as high as 69Ah. They have a BMS attached to them, but unless you have the commands to turn it on, it will be non functional. The connector to the BMS looks like the JXT connector, but there are two negative and two positive wires, so it will not be a direct plug and play. Removing the extra pins would be pretty easy. You can also remove this harness completely and install your own. Each contact point has a spade connector, removing the harness for modification would be extremely easy. Each spade connector and battery terminal is labeled for easy reinstallation of the voltage sense harness.
There are no mounting holes on this module, so you will have to strap the module down in some fashion.

Battery arrived quickly and packed very well. The pack preforms good as it is addition to my solar storage and is a cost effective option to purchasing full built batteries specially as I am on limited budget this works well without breaking the bank.

Great value for lithium prebuilt, bought a bunch to build some golf cart lithium batteries, cutting off 2 cells of one group for a 14s and have had zero complaints where else are you going to get 134ah nmc 51.8v nominal 58.8v max for $480 add 150 for bms abd 40 for abs battery box $670 all in.

Battery is great so far. I ordered another one May 8.
Have to request shipping and tracking info. Really would like to know where & when.

Great batteries. I bought one initially for a solar setup and decided to get another one. The BMS on these still work but it’s a proprietary one so you won’t be able to re-program it.
