The battery powered high-wattage appliances like a heat gun and a hot plate without any issue. When the discharge current reach to 190 amps, the 150A BMS triggers the overload protection and automatically recovers after 30 seconds.

Even under heavy load, the battery maintained stable output, proving its reliability for demanding applications.

5. Charging Testing

Next, we tested the charging efficiency of the Redodo 12V 140Ah battery. The battery was charged using a LiFePO4-compatible charger.

Additionally, the low-temperature cut-off protection worked as expected, ensuring longer lifespan and safe operation in cold environments.

6. Final Verdict

After testing the capacity, discharging performance, and charging protection, we can confidently say that the Redodo 12V 140Ah Bluetooth Lithium Battery lives up to its specifications. It delivered reliable, consistent power for high-wattage appliances, and its advanced BMS ensures safe and efficient operation.

If you're looking for a high-capacity battery with Bluetooth monitoring and reliable deep-cycle performance, this battery is a solid choice.

User Review of Redodo 12V 140Ah Bluetooth Lithium Battery

After going through the detailed performance and testing analysis, let's take a look at what actual users have to say in this Redodo battery review. Here are some highlights from user reviews:

@Dave:

Ordered and installed two Redodo 140AH LiFePO4 smart batteries in my disaster response trailer. Needed the largest AH that I could get in a Group 31 package. They support 12 DC lighting and a 3000 watt inverter for charging tool batteries and running other small tools when not on a generator or shore power. They work well.

@Tom:

I bought this battery for portable ham radio. I upgraded from my previous 54Ah battery to this 140Ah. I wanted a bit more time on the radio than I had before, and this battery definitely fits the bill. More than 4 days of standby on my FT-991A. Still putting it through the paces.

I also purchased the Redodo 14.6V 20A LiFePO4 Battery Charger. Absolutely NO RF NOISE from the charger! That was actually the biggest and most satisfying surprise, since the charger I use on the previous battery made a LOT of noise.

@Curtis:

I have an older Class A motorhome that I plan on upgrading house batteries is, soon, and I will definitely be using Redodo, when I figure out the logistics and make the switch.

These batteries run my 12V fridge and barely go down 10 percent every night. Love the Bluetooth features and being able to shut them off when done.
