14s 51.8v 62ah 3.2kWh lithium ion module

These are beautiful packs that are checked to make sure all cells are balanced. These came out of backup power units and were only used as backup for 4 years. You will have to add your own BMS. We recommend on 14s BMS on each module. The balance leads can easily be accessed by popping off the plastic lid and removing the 15 wire harness from the top board. You will have one wire for your main negative and the other 14 wires will go in order from 1st cell positive to 14th cell positive. Just connect those wires in proper order to your BMS. We don't know anything about the original BMS included and it likely can't be reused so just save yourself some time and order the BMS when you order this module. The BMS on board is likely just a BMU that communicates to a main system so that board may only offer balancing.

These will have to ship freight. The more you but the more you'll save since we can ship a lot on 1 pallet. We have excellent freight rates and they include residential and lift gate fees. You can also pick up at our Bensalem, PA location. These weigh 58 lbs and we don't trust Fedex or UPS to handle these with care so we are doing freight only or local pickup. Its rare we get 48v batteries like this that test great and we don't want to see any get damaged during shipping. 

Under $125/kWh for batteries that test great, perfectly balanced, and are the perfect 14s set up which works for all ALL 48v inverters.

Each module fully charged is 58.8v (4.2v/cell) and fully discharged is 39.2v (2.8v per cell). This unit is rated for 1c discharge rate to 62a continuous so 1 module can easily push 2500w. If you have a golf cart or powerwall this module can't be beat. The price is right. If you have a 5000w inverter, 2 of these in parallel each with a 60a or 100a BMS will be a great pairing.

Each module is 12" tall, 12" wide, 9" deep
