Fails after one year in campervan use
After just over a year of use in a campervan, the battery stopped supplying useful power. It drained overnight under a 3.5 amp draw from a 12V refrigerator, charged to progressively lower levels, and eventually would not accept a charge. The BMS appears to be in low voltage cutoff. Early on it performed well, arriving on time and well packaged, charging quickly from 500W solar panels, and running a 12V refrigerator and 800W microwave without issue. It included extra bolts and color-coded protective covers. The stated 5-year warranty applies only to direct purchases, not this one.
Pros
- + arrived on time and well packaged
- + charged quickly from solar panels
- + ran a 12V refrigerator and 800W microwave without issue
- + included extra bolts and color-coded protective covers
Cons
- − failed after just over one year
- − drained overnight under a 3.5 amp draw
- − charged to progressively lower levels
- − would not accept a charge
- − BMS appears to be in low voltage cutoff
- − 5-year warranty only for direct purchases

Reliable Power for Home Solar Setup
These batteries are used in a home solar setup with an inverter and solar panels. They provide stable power and last a long time for daily use, and connecting them to the inverter is simple with smooth operation from the start. They offer peace of mind during travel, as the system continues running reliably. Performance has exceeded expectations and they feel like a great investment. The only suggested improvement is a more detailed instruction manual for those less experienced with solar installations.
Pros
- + stable power output
- + long-lasting for daily use
- + simple inverter connection
- + reliable operation during travel
- + great investment
Cons
- − instruction manual could be more detailed

Solid Lithium Batteries for RV Power
These 300Ah LiFePO4 batteries deliver strong performance in an RV setup, with two units providing ample power for a residential fridge and more. Installation went smoothly, though an initial deep discharge message on a battery monitor required a software reset. Build quality is reported as high based on an independent teardown, and the price is competitive. Delivery was timely and packaging protected the batteries well. Lithium offers advantages over AGM, including lighter weight and deeper discharge. A full lithium system upgrade is recommended for older RVs.
Pros
- + good price
- + high build quality
- + timely delivery
- + well packed
- + ample power for RV needs
- + lighter than AGM
- + deeper discharge than AGM
Cons
- − initial deep discharge message required software reset

Good no-frills LiFePO4 battery with minor charging quirk
A no-frills, non-smart LiFePO4 battery that is well priced, feels solid, and is lightweight for its size. It works well for recharging power stations and for shelf storage as emergency backup. However, half of the units arrived at low voltage and would not charge until jump-started from another battery, raising concerns about BMS settings or used cells. One box arrived with a hole, though the battery appeared undamaged. Overall, a satisfying purchase that would be bought again if space allowed.
Pros
- + good price
- + non-smart design without Bluetooth
- + appears well built and not cheap
- + lightweight for size and amperage
Cons
- − some units arrived unable to charge without a jump start
- − concern about BMS settings or used cells
- − one box arrived with a hole
