LiTime Battery Balancer for 24V/36V/48V Battery Bank
【Up to 48V Battery Bank】LiTime Balancer boasts 4 distinct connection ports, enabling seamless integration with 48V battery banks. This versatility is ideal for building a robust 48V battery bank, achieved by combining 16 units of 12V batteries in a configuration of 4 in parallel and 4 in series. Compatible with 24V, 36V, and 48V battery banks, it is a perfect choice for diverse applications, such as RVs, golf carts, trolling motors, and off-grid systems.
【Proactive Protection】The LiTime battery balancer is equipped with reverse polarity protection and high-temperature Protection. The robust reverse polarity protection mechanism offers you peace of mind against accidental wiring errors (do not reverse it for a long time). The high-temperature protection safeguards the battery balancer against overheating, a common issue that can lead to performance degradation and safety risks.
【Prolong Battery’s Life Span and Cycle Times】With these comprehensive active balancing functions, the LiTime battery balancer not only optimizes battery performance but also extends its lifespan. You can squeeze the full potential of batteries and achieve longer cycle times and overall improved performance. Whether you use it for your recreational vehicle, energy storage system, or other applications, the LiTime battery balancer is your trusted companion for optimizing your battery's life.
【Suitable for Multiple Battery Types】The LiTime 48V battery balancer is suitable for multiple battery types on the market, including LiFePO4, GEL, SLA (Sealed Lead Acid), FLA(Flooded Lead Acid), and other rated-voltage batteries within 3-20V. Compatible with an extensive range of battery types available in the market, it can cover all your needs.
【Auto Balance Mode and Standby Mode】As a voltage difference appears among the connected batteries, LiTime battery balancer will auto start working until the voltage difference is under 10mV. The maximum working current is 10A, which works for all 12V batteries at all capacity. If the voltage among the connected batteries is less than 10mV, the balancer will automatically turn into standby mode, only drawing less than 5mA from the battery bank.

FAQ
Q: What is battery cell balancing?
A:
Cell balance refers to a condition where all individual cells have uniform capacity and voltage. When lithium-ion cells are connected in series and parallel, the manufacturer ensures that they share the same voltage and chemistry.
Q: Do I really need a battery balancer?
A:
Balancing is necessary for packs that contain more than one cell in series. Parallel cells will naturally balance since they are directly connected to each other, but groups of parallel wired cells, wired in series (parallel-series wiring) must be balanced between cell groups.
Q: What is the difference between a BMS and a battery balancer?
A:
A Battery Management System (BMS) and a battery balancer serve distinct functions in managing battery packs.
A BMS is responsible for monitoring and managing the overall health of the battery pack. It oversees factors such as individual cell voltage, temperature, and current, and ensures the battery operates within safe limits. Additionally, a BMS often includes features such as overcharge protection, over-discharge protection, and cell balancing.
On the other hand, a battery balancer is specifically focused on equalizing the charge among the individual cells within a battery pack. It works to ensure that each cell maintains a similar state of charge, which is crucial for the overall performance and longevity of the battery pack. While a BMS may include balancing functionality, a dedicated battery balancer is designed solely for this purpose.

Connecting this Li Time battery balancer was no more difficult than connecting a 12v battery charger.This is my first balancer. I got it for a pair of 12v LiFePo4 batteries that I want to put in series. I didn’t want to have to deal with keeping the batteries balanced. I want to hook it up and safely forget about it for a while.I was initially surprised by how thin the product manual was (a few pages) till I looked at the balancer and read the instructions. To use, you connect the red/black pos/neg ring terminals to you batteries in pairs starting on the bottom left of the unit and moving to the right. It supports 24/36/48 volt battery banks. Since my bank is 24 volts, I only connected the left two pairs. That’s it. Super simple.The ring terminal leads are each 18 inches long. All the ring terminals have an insulating tube around them to prevent an accidental short circuit. I augmented that with electrical tape to make sure the tubes stayed it place.It has kept my two batteries balanced. To verify that it is working, simply measure each battery’s voltage with a multi-meter. A status LED would be nice, but that would have added more parasitic drain. I’m okay with using a meter.One final note, the balancer does use a little power. If you are frequently charging, as with solar, or you have a charging device always connected, then the drain isn’t an issue. If you are essentially storing your batteries, I’d disconnect the balancer.

Although this is a LiTime product (a name I recognize in LiFePO4 batteries) this product will work just fine with other brands of batteries such as my ECO-WORTHY LiFePO4 batteries for my solar setup. I often just use a single LiFePO4 battery or connect a single pair of big LiFePO4 batteries in parallel (since currently all of my inverters are 12V) but this was just what I needed for connecting a pair of big LiFePO4 batteries in series to keep the two batteries balanced when I'm testing 24V setups. I have a number of different solar charge controllers and many can handle either 12V or 24V battery systems but they can process more solar input (Watts) when connected to a 24V system so I've been experimenting with a 24V setup and this balancer gave me more confidence to use a 24V setup. So far it seems to do a good job of keeping the batteries balanced.

Experiment: beginning with two 12V LiFePO4 batteries,
-The first battery is 3.5Ah at 13.25V.
-The second battery is 2Ah at 13.0V.
Upon connection to the LiTime Battery Equalizer, both batteries dropped to 13.05V.
After 8 hours, both batteries dropped further to 12.89V.
Observation: it appears that this balancer/equalizer incorporates a dummy-load that absorbs energy, causing a faster reduction in battery voltage. Consequently, I will only deploy this balancer/equalizer in applications that strictly necessitate voltage balancing.

It was easy to install with the included directions. I am using it in a 24v configuration, so you only use the first 2 pairs of wires. I honestly can't tell you if it is working yet or not because this unit doesn't have any lights or displays on it. I really thought that the Li-Time unit would be one of the better balancers, but so far, I can't really tell if it's working other than the batteries appear to be staying fairly close in voltage. I will be load-testing it more in the spring once it is hooked up to my camper again, but right now, it is just a spare power supply in my basement. I haven't been able to give it a good test with a high load on the batteries to see how it recovers and re-balances, but my batteries are very close in voltage right now.. Li-Time needs to add a display with display with voltage/watts/amps for each battery. It does have a very solid and sturdy feeling of quality compared to other balancers I have used.

Do your research before using, other than that it is great.
