200Ah Version Disappoints Compared to 100Ah

The 12V 100Ah version performs well and is highly regarded. However, the 200Ah version lacks a BMS that is compatible with the XiaoXiang Android app, which is a significant drawback. This incompatibility leads to frustration and makes the 200Ah model a poor choice compared to the 100Ah alternative.

Pros
  • + 12V 100Ah version works well
Cons
  • − 200Ah version lacks BMS compatible with XiaoXiang Android app

Accurate Capacity and Strong Support for LiFePO4 Battery

A 280Ah battery delivered 266Ah before the BMS shut down at 10.6 volts, tested with a current-measuring monitor while running an RV refrigerator at a fairly constant 26.5 amp load. Voltage readings varied by as much as 0.5 volts across locations, including on the battery itself, so voltage alone is unreliable for gauging residual capacity. The smaller form factor fit better than a full-size 240Ah unit and increased capacity. Support responded promptly and professionally to all questions, making another purchase from the brand likely.

Pros
  • + Smaller form factor fits better
  • + Capacity increased to 280Ah
  • + Delivered 266Ah in test
  • + Responsive and professional support
  • + Timely answers to questions
Cons
  • − Voltage readings vary by up to 0.5 volts and are unreliable for residual capacity

Batteries arrive on time but support info is hard to find

The batteries arrived on time and appear to be in good condition. However, finding customer service and support information proved difficult, as links only led to more products and no direct contact details were available. A request for battery data needed to adjust the charge controller could not be fulfilled initially. After contacting the company by email, responses came quickly, but no web page or data sheet was provided, and the stated 10-year warranty lacks verifiable company information. Overall, the experience feels unprofessional.

Pros
  • + batteries arrived on time
  • + batteries look great and seem fine
  • + quick email response from company
Cons
  • − difficult to find customer service and support info
  • − no web page available
  • − no data sheet provided
  • − warranty lacks verifiable company information
  • − unprofessional experience

Strong capacity and build, but gauge is unreliable

Used in an RV to replace lead acid batteries, this 12V 240Ah LiFePO4 battery delivered close to its rated capacity, holding voltage well past 90% depth of discharge and still starting a generator. Build quality and included hardware seem solid, and support responded within 24 hours. The main drawback is the built-in voltage/capacity gauge, which read 65% remaining after 200Ah had been used, making it misleading without a separate monitoring system. A second unit was ordered, and it handled a large, quick discharge from a 2500W inverter/charger without issues.

Pros
  • + Delivers close to rated capacity
  • + Solid initial build quality
  • + Quick support response
  • + Handles large, quick discharges
Cons
  • − Built-in voltage/capacity gauge is inaccurate
