24v 48ah 1.25kWh POWER Module - 2,000 Cycles!
The more you buy the more you save! Freight charges stay around the same cost since a 2 pack and 8 pack all get priced as 1 pallet. These are a little heavy to ship safely by ground so we are only shipping these freight. We also offer FREE pickup from our Bensalem, PA location. We get excellent freight rates which includes lift gate and residential delivery. Shipping only available to the lower 48 states and Canada.
Each Module contains 42 SPIM08HP cells, busbars, holders, and already in 7s6p 24v configuration. This is the best value battery available in 24v/48v configuration with a 2000 cycle rating! Two of these in series makes a perfect 14s 48v battery. You even get posts to add your BMS balance leads with ring terminals. You will need a 7s BMS for 24v or if you buy 2 you will need a 14s BMS. You must fully charge each module before making your series and parallel connections. 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. Our customers are powering homes, forklifts, golf carts, RV's, etc with these modules. We actually have 2 of these in series powering one of our forklifts. You should always use a BMS.
These were used as backup starting power for cold climate generators. Therefore these have not cycled too many times. Likely less than 1 full cycle.
Module weight is 44 lbs.
Pack Dimensions 19" x 9" x 6" (add an inch for brackets and wiring clearance)
Fully charged voltage 29.4v (4.2v per cell)
Nominal Voltage 25.9v (3.7v per cell)
Fully discharged voltage 19.6v (2.8v per cell)
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.
