14s 51.8v 55ah 2.85kWh lithium ion module
These are beautiful packs that are fully tested and around 99% capacity. These came out of backup power units as shown in the photos. You will have to add your own BMS. We recommend a 14s Daly BMS. The 2nd photo shows how easy you can add your own BMS. There are literally screws that you just add a ring connector to your BMS leads and screw them on. You don't even need to solder anything. I 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.
Freight is a flat $350, if you buy 1 or 10 the total for shipping is only $350. That includes residential delivery and lift gate service. We only have a few of these, they just got done testing and they will go fast at this price. You can also pick up at our Bensalem, PA location. These weigh 58 lbs and I 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 like new and I don't want to see any get damaged during shipping.
These were used as BACKUP ONLY which means these have only been cycled a few times and explains why they are testing so good. Again, these are tested and ready to go. Under $150/kWh for batteries that test like new 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 55a continuous so 1 module can easily push 3000w. If you have a golf cart or powerwall this module can't be beat. The price is right and it tests like new.
Each module is 12" tall, 12" wide, 9" deep
