Powerful LiFePO4 Battery for RV Boondocking
This battery exceeded expectations during a 4-day boondocking trip in an RV, powering a CPAP nightly, fans, lights, and occasionally an inverter for appliances. It returned home with about 70% charge, and the app estimated 110 more hours at that usage rate, a major improvement over lead acid. Installation is easy, though finding a group 32 battery box was the hardest part. The included screw-in terminals allow flexible connections. Charging via the RV is slow, recovering about 140 amp hours in 8 hours. The Bluetooth app works well, finds the battery instantly, and provides live status updates even without service.
Pros
- + exceeded expectations
- + long runtime
- + easy installation
- + versatile terminals
- + convenient Bluetooth app
- + works without service
Cons
- − large size requires specific battery box
- − slow charging via RV

Impressive LiFePO4 Battery for Boat Stereo
This battery is a strong performer for the price and meets its rated capacity. Used as a replacement for two Optima Yellowtop batteries that were drained by a boat stereo in under an hour, it powers a large system with four amplifiers, twelve speakers, and six subwoofers while using only 12–15% of its amp hours over three hours. The iOS app works well. It is not rated as a starting battery, though it is reportedly capable of that use.
Pros
- + meets rated capacity
- + long runtime for high-demand stereo
- + iOS app works well
- + good value
Cons
- − not rated as a starting battery
