Community Reviews

This Humsienk 12 volt 100 amp hour LiFePO4 battery looks like a strong low cost upgrade for solar, RV, and trailer use. Real world setups with multiple batteries have run air conditioners and other loads for 18 plus months without issues, and the brand line has also held up in a 48 volt golf cart install. The main cautions are the 100 amp BMS, no Bluetooth, and the need for a lithium compatible charger. Mixing ages or battery types can also shorten life or cause uneven loading.

  • Solar builders pairing matched batteries with a lithium-compatible charger, because the batteries can charge well from solar and a proper converter.

  • Battery banks that will stay within one matched set, because mixing different ages or lots can shorten the newer battery's life.

  • RV owners running a 12V air conditioner from solar and shore power, because four batteries have handled daily use for 18+ months without issues.

  • Off-grid setups that need lithium batteries to tolerate deep discharge, because LiFePO4 can be taken to 0% without permanent damage.

  • Users who want built-in battery monitoring, because this battery has no Bluetooth and depends on the BMS for protection.

  • Owners planning to mix batteries of different ages in one bank, because uneven voltages can make one battery carry more of the load and shorten the newer battery's life.

  • High-demand setups that need a larger protection margin, because a 100A BMS may be too low for the battery.

You also don't really want to mix and match lithium batteries of different ages/lots or you will get much lower life out of the "newer" battery.

it is my understanding that you don't mix and match within the BMS. Outside of the BMS you can mix and match as much as you want as long as each matched set has their own BMS.

even if you're outside of the BMS, if the battery voltages are differing some amount, whether from the battery aging or degrading, you will not draw from them equally, so one battery is taking more of the load.
