WattCycle 12V 314Ah Compact LiFePO4 Battery | 4.01kWh, 200A BMS - Top RVs Battery for First-Time Buyers

Good so far.

I took 8 of these 12V 314Ah batteries and built a 4S2P battery bank for my hybrid solar system. The batteries have been performing well so far. No complaints.

Huge capacity in a small size

I bought this to upgrade from a 100ah lithium battery in my travel trailer. It more than tripled my capacity and easily fits in the factory camco double battery box with no modifications required. The price was great and I highly recommend this.

Balancer mA way too low for cells of this capacity

35mA-50mA for passive balancer for 314Ah cells is ~10x too small to be effective in any reasonable amount of time. Please increase these resister values and add a small heat sink if necessary. Otherwise, a good battery. Took a very long time to bring 4 of them in-line. Internal resistance variances as usual. Good value for the capacity, weight and size.
