100Balance 1A Smart Active Equalizer Balancer 4S for Lifepo4 LFP/Lipo Li-on/LTO Lithium Battery Group BMS Energy Transfer Board with Bluetooth App(4 Cell)

I installed the 1 Amp version of this in my 16 cell LiFePO4 battery, which has one cell that has a slightly lower capacity. The battery typically charges / discharges around 50 Ah each day and this keeps the cells in line. The passive cell balancing in my battery BMS is not able to keep the cells balanced. When the battery is nearly empty or full this keeps the voltage of the weak cell high or low enough to keep the BMS happy. I no longer have to keep balancing the cells manually.

I have a li-ion battery connected to my solar inverter. My state of charge was never quite reaching full capacity and I wasn't getting my batteries full potential because a couple of the cells voltage we're not the same as the others. After using this balancer, it made a huge difference - My state of charge was able to reach 100%, and I'm now able to get far more out of my battery than I ever have.The balance is highly worth the cost. It is easy to set up - If you have an existing BMS you could even connect each cell wires to the ones already on your BMS. A+ service. Good communication.Highly recommended

If you are home building a battery system in your home or embarking on van life. This100Balance Smart Active Equalizer Balancer works with a variety of lithium battery types including Lifepo4, Li-on LTO. The kit includes the battery balance module; that you can mount to a panel close to the batteries. The pack includes 14 leads; one is coloured black that you need to connect to the main negative terminal of your pack. Then you can connect to the terminals on your batteries/ pack in sequence. The cables are supplied tinned; but to make it tidy you might be better cutting the cables down to length. You will need to solder the wires onto connectors or tabs on your battery packs. When its installed; you connect the multi pin terminal into the balancer; and plug the Bluetooth module into its terminal (there is a connector you can get separately to monitor via a computer.) When its powered you can use the 100Balance app to configure and monitor the balancing. Once enabled you can leave it to look after your batteries; it balanced out my 3-test battery setup balancing the voltage across the packs whilst they charged. This balancing during charge and discharge should make the investment in your batteries last longer; and if you keep things charged a lot of the time you should get more power from your system as the charging is in a better place.I found it is easy to install; it works fine with small PO4 pack setups; like mine and will be able to grow with you.

I have a battery pack which due to a fault in the battery "balancer" that came with it failed, became unusable.I removed the faulty cells in the pack, (two), and have replaced the failed balancer with this, and it does seem to be working fine.The very basic idea of this unit is to ensure all the cells are the same voltage, by monitoring the voltage of each cell, and balancers the cells so they are all set the same, which improves efficiency and battery life. Time will tell if it works well, but I note it only works with a minimum cell voltage down to 3 volts, (this is in the specifications of the unit). I would have liked it to operate lower than that, but that is its specification, so I have not deducted any stars.It is running cool, and the pcb well protected by its case, and the connecting leads are a good length, and I had no problem routing them. I also like the idea that the unit is unpluggable, and the connector is good, as on my original one unit, they were soldered directly to the pcb.Recommended, and I think good value for the money.

I recently integrated the 100Balance 1A Smart Active Equalizer into my battery management system (BMS), and the results have been impressive. Designed for 13S configurations, this equalizer offers advanced features for Lifepo4 LFP, Li-po, Li-on, and LTO lithium battery groups.The inclusion of Bluetooth connectivity, accessible through the dedicated app, sets this equalizer apart. The ability to monitor and control the energy transfer board remotely provides a convenient and user-friendly experience. This feature has proven invaluable in ensuring optimal battery performance without the need for constant physical checks.The 1A smart active equalizer function is a standout feature, efficiently balancing the cells within the battery group. This ensures longevity and maximum capacity utilization, addressing concerns related to uneven cell voltages commonly associated with lithium batteries.Installation was straightforward, thanks to clear documentation and a well-designed interface. The build quality of the equalizer instills confidence in its durability and reliability, crucial factors when dealing with sensitive battery systems.Overall, the 100Balance 1A Smart Active Equalizer has elevated my BMS setup to a new level of efficiency. The blend of cutting-edge technology, user-friendly app integration, and robust balancing capabilities make it an excellent choice for anyone seeking reliable battery management for their lithium battery groups.

This is a great bit of kit to add to a pack of recycled cells in a solar array.While the BMS can have balancing built in, often on cheap ones the balancing only works while the BMS is charging the packs, however with this added into the system you get configurable and monitorable trickle balancing at all times (the device is powered by the pack), meaning that you should never have unbalanced cells again.The app, and the windows desktop app both fell a little bit unpolished, but they do work and the numbers seem to match reality which is always good to see.Its probably too early to call this a long term success at this point, but I am very optimistic this is working as intended and will aid in the life and longevity of my pack, time will tell.I will come back to update if anything changes over time.
