48V 50Ah LiFePO4 Battery Pack
This page describes a 48V pack at 50Ah, model YB-LP4850H-8 as listed, with a nominal voltage of 51.2 V and an energy figure of 2560 Wh. It is the smaller of the two listed general 48V packs on this site, and it is also the 48V specification page for buyers who need a representative 48V model with a full listed specification.
Listed specification in context
The charge voltage is listed at 58.4 volts, plus or minus 0.2 V, and the charge current at 25 A, with a maximum of 50 A. The discharge current is listed at 25 A, with a maximum sustained current of 50 A and a pulse current of 50 A on a 10-second setting. The cut-off voltage is listed at 40.0 V. Those limits should be checked against the existing inverter or charger settings, because a 48V system is not defined by its nominal voltage alone: the charge voltage and the cut-off voltage decide whether the equipment can work with the pack.
Cycle life is listed at 2000 cycles under a stated condition: charging and discharging at 0.2C down to 70 percent capacity. The internal resistance is listed at no more than 35 milliohms, and self-discharge at no more than 3.5 percent per month at 25 degrees Celsius. The cell arrangement is listed as a 16-series, 1-parallel arrangement, the housing is plastic, the protection rating is IP55, and the weight is listed at about 22.7 kg. The temperature ranges are listed as charging from 0 to 45 degrees Celsius, discharging from minus 20 to 60 degrees Celsius, and storage from 0 to 45 degrees Celsius.
Use and limits
A battery management system watches the cells in a pack and disconnects the pack when a limit is crossed. The exact limits depend on the model, so buyers should check the protection list for the model they are considering rather than assuming every pack in a range shares the same list. In the models listed on this site, protection typically covers over-charge, over-discharge, over-current, over-temperature and short circuit, with cell balancing on some models only. Where a model page does not list balancing, it is not claimed for that model.
At about 22.7 kg, this pack needs a planned mounting position. The dimensions in the listed specification - 522 by 238 by 217 by 217 mm - should be checked against the available space, including cable access. A buyer comparing this pack with the 100Ah model at the same voltage should compare weight, current limits and dimensions together, because the two packs share a voltage and a housing size in their listed specifications but differ in capacity and weight.

Frequently asked questions
How do I get a quotation?
Send an enquiry with the voltage, capacity and quantity you need, plus the application. Quotations are confirmed per order, and specifications are confirmed per model before payment. This site does not list fixed selling figures.
What certification documents can you provide?
ISO 9001 is stated by the company. Certificates are available upon request. If a buyer needs a certificate for a specific model, ask for it in the enquiry and name the model, so the correct document can be checked.
Are the specifications on this page valid for every model?
No. Specifications are shown per model and must not be read across the whole range. Where a value is not listed for a model, the page says to confirm per model rather than filling in a generic figure.
