36v 48ah 1.78kWh SPIM08HP POWER Module
These batteries come with a steel enclosure which can also be mounted.
This product must ship freight which is calculated. The more you buy the cheaper it gets per battery for freight. We include residential and lift gate service. Or you can pick up for free from our Bensalem, PA location.
60 SPIM08HP 3.7v 8ah cells, busbars, holders, and already in 10s6p 36v configuration with proper compression and mounting brackets. It saves us a lot of labor breaking down to cell level so this is the best deal on SPIM08HP cells. You are basically getting 30x of the 2p 3.7v 16ah cell modules for just $5.67 each plus all the busbars. You even get posts to add your BMS balance leads with ring terminals. This module is built to push 500 amps continuous and can pulse over 1000 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, EV, high power E-bikes, etc. This one battery offers more than enough power to push a standard 36v golf cart. We actually have 2 of these in parallel running one of our forklifts. You should always use a BMS but many customers use the BMS for charge only then use a voltage display and run the discharge direct. You can easily make a 20s 72v module with 2 of these in series.
Most 36v golf carts and forklifts come with 550a controllers. You can use 2 of these modules, add a 300a BMS to each module, then parallel the 2 modules when they are the same voltage. This is the most economic friendly golf cart or forklift build with BMS protection. Between the 2 300a BMS units in parallel you will have protection above the 550a controller rating and also the cells can easily handle the energy demand.
You also get 2 12v fans. If you want you can actually set up a temperature system that triggers the fans on and off. Each fan has a positive and negative wire. To power the fans with this battery you can connect the fans in series to make a 24v fan system. Use a temperature sensor to trigger the fans on and off. The fans will blow air through the enclosure as they are built for that. You can also add a heating element to these batteries which we also sell and they fit inside the hole where the fans are. In theory you could have over temp trigger just the fans and under temp trigger the fans and heating element.
These were used as backup starting power for cold climate generators. Therefore these have not cycled too many times.
The fan assembly unscrews within seconds if you want to remove that part. The enclosure is just screws as well. We recommend keeping the enclosure together because it is steel and adds a nice layer of safety. Just remove the top of the case to gain access to add your BMS.
Module weight is 75 lbs.
Pack Dimensions 24" x 9" x 6" (add an inch for brackets and wiring clearance)
Fully charged voltage 42v
Fully discharged voltage 28v
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 6p configuration in theory can be charged up to 720 amps and can discharge at 1200 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.
