24v 24ah 621.6wh 21x SPIM08HP 25.9v POWER Module
For those of you looking for SPIM08HP cells this is the product you have been waiting for.
If you need a 48v battery you can buy 2, charge up each module, then connect in series. Add a 14s BMS.
Each module has 21 cells, busbars, holders, and already in 7s3p 24v configuration with proper compression and mounting brackets. You even get posts to add your BMS balance leads with ring terminals. This module is built to push 300 amps continuous and can pulse over 600 amps! This is a true power module, if you need a lot of power in a small space this is what you want. Or if you want to power a forklift, golf cart, trolling motor, RV, high power E-bikes, etc.
These were used as backup starting power for cold climate generators. Therefore these have not cycled too many times. Every module of the 100+ modules we tested was above 90% capacity and we averaged near 100% full capacity. We do large batch tests on these when they come in and also check that every battery is reasonably balanced. Realistically you can expect between 95-105% capacity on these since they were only used as backup starting power and likely never fully cycled.
Module weight is roughly 28 lbs.
Pack Dimensions 13" x 9" x 6" (add an inch for brackets and wiring clearance)
Fully charged voltage 29.4v
Fully discharged voltage 19.6v
The busbars are copper and depending on the temperature amperage rating you can easily push much higher than we stated earlier. The cells themselves being in 3p configuration in theory can be charged up to 360 amps and can discharge at 600 amps. Of course we don't recommend to push any battery to their maximum levels. Also these are not your typical 300-800 cycle lithium cells, these are rated for over 2000 cycles and many of our customers have built these cells into their own modules before we were finally able to negotiate getting the entire modules with the busbars and holders.
We cover the $37 hazmat fee and UN-4G packaging. We are fully certified to legally ship these.
