How do I monitor the battery status?
The group 24 battery smart battery built-in Bluetooth feature lets you monitor your battery's real-time status—including state of charge (SOC), voltage, current, cycle life, and temperature—directly from your smartphone. Just download the Dyness Battery App, enable Bluetooth on your phone, and select your battery from the list of available devices. No extra hardware is needed.
What to do when receive the battery?
Please charge the Bluetooth battery first after receiving it. This will ensure that the battery can be turned on and the Bluetooth connection is established. (Our Bluetooth batteries are delivered in the off state, the virtual voltage of the battery terminal is 3V-5V, this is a normal phenomenon, just use the AC-DC charger or MPPT solar charge controller to charge the battery and turn on the battery, it can be used normally.)
Note: When charging the Bluetooth batteries for the first time, the power level may stay at 99% for several hours before reaching 100%.
If you intend to store the battery for an extended period without use, we recommend charging it to a SOC 50% and conducting maintenance every three months. These measures will help preserve its functionality and performance in the long run.
Does the Dyness Group 24 bluetooth battery has low-temperature protection?
Yes, this group 24 battery has low-temperature charging-off protection. It's recommend to charge the battery during the temperature range: 0℃ to 50℃ / 32℉ to 122℉.
Recommended reading on LiFePO4 Temperature Range Guide for more information on safe usage and performance.
For optimal performance, charge the battery indoors on cold days.
How many group 24 bluetooth batteries can I connect in sereis or parallel?
You can easily expand your power system using Dyness Group 24 batteries by connecting them in various configurations.
Series Connection: Connect up to 4 batteries to increase voltage to 51.2VV.
Parallel Connection: Connect up to 4 batteries to increase capacity to 400Ah.
Series-Parallel Connection: Build a larger bank of up to 16 batteries (for example, a 4-series and 4-parallel, or 4S4P, setup).
Important Rules for Connecting Batteries
For your system to operate safely and perform optimally, all connected batteries must meet the following criteria:
Same Specifications: They must have the identical capacity (Ah) and BMS (Battery Management System) current rating (A).
Same Brand: Only connect Dyness batteries with other Dyness batteries. Different brands often have incompatible BMS programming, which can lead to system failure.
Purchased Recently: All batteries should be purchased within a short timeframe (ideally one month) to ensure they are from a similar manufacturing batch and have balanced internal characteristics.
How to charge Dyness Group 24 Bluetooth lithium batteries?
1. Using Solar Panels
The battery can be fully charged in one day (with effective sunshine 4.5 hrs/day) by 400W solar panels. It may take more than one day to fully charge the battery by ≥400W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.
2. Generator/Alternator
If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations. The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current:
① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity;
② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
3. LiFePO4 Smart Chargers
To charge 12V battery, it is recommended to use 14.6V battery charger.
The Recommended Charging Voltage: 14.2V - 14.6V.
The Recommended Charging Current:
① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity;
② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

After changing to this one with Bluetooth function, after downloading the APP on the mobile phone, you can turn on Bluetooth to view the battery level and remaining battery life in real time, and even check the charging and battery health status. You can monitor it remotely while lying in the RV. It’s so convenient!
Great batteries! The BMS from Dyness is far superior to other systems I’ve used. I can easily check the battery status anytime from my phone, and the Bluetooth range is excellent. This is already my second order from this company — highly reliable and worth every penny.
excited about using your products on my new ranger z519 I bought in April of this year. I am 77 years old and still fishing.
