LiTime 48V Battery Balancer, Active Equalizer for 24V/36V/48V Battery Banks | For 4×12V LiFePO4/FLA/SLA/GEL Batteries, Extend Battery Life, Designed for Home, RV, Solar System, Trolling Motor, Off-Grid

The darn thing works, survived an accidental short too. Not a high power item, give it a over night to equalize larger batteries. Mine are a set of 4x 12V 200AH LiFePo4s. I used to have 30% and more discrepancies after only a couple cycles, now it’s within 6% during charging from 10% and less than 1% after charging to 80% or more. Equalizing is not as good for a half charged battery set, but still good enough. Recommend this any time, price is good too.

Works great!! It really works! It completely prevented sudden shutdowns and improved the maximum charging voltage; my batteries no longer discharge prematurely and charge fully. My inverter stopped giving overvoltage errors.

Easy install and works as it should. Wires seem a little thin, but everything hooked up fine. Might be a hard reach for 4 batteries, had to center it for 3. Battery 1 was taking a full charge first and draining first, leading to a lot of overcharging/discharging and low voltage lockout. Now, all 3 12 volt batteries charge and discharge evenly. It whistles a little, though.

Seems to work! No visual indicator, but a voltmeter shows the batteries (4) are perfectly balanced. Wish it had an LED or 2 to indicate if it was on or actually working and if it's balancing up or down between any connectors. Note that the wires are a bit short for 4 batteries in a series, as the furthest connectors are just out of reach. Had to splice and add wires. I'm good with doing this , but not everyone would be. Ideal product would have 4 volt readers and an led showing direction of any balancing. But that's not fair to judge a product on what I wish it was. I knew what I was buying. Didn't ding them for this. Just a suggestion of something I would buy

Solved my battery discharge problem on lithium batteries....they are all staying the same voltage now

I have had this for 2 I/2 months now and it's a complete failure. I have 4 12V batteries in my golfcart. I desulfurized my batteries, I individually charged each battery and let them rest. I did this 4 times over a month. Balancer did nothing. Batteries actually got worse with this device connected. I can't even give it 1 star because device is useless but had to do at least 1 to publish the review!

Have installed several of these on both 48 and 36 volt golf carts with multiple series connected batteries any it solves all balance issues

Very good have a problem with one batery and this is mysolution

All 3 batteries have stayed pretty much the same since connection, works as it should! Update: ordered my second balance,the package arrived empty but Susan at Li Time was prompt to act and my second(third) arrived it will be hooked up to my second bank of batteries later today. The package was shipped in its own box for the third time with still no seal,anyone can easily take the unit out of the box during shipping and no one would know where it disappeared!!!

First off, what I like about this device is heavy and looks sturdy which gives me some confidence, but the most amazing thing is it works as I heard from others. I just set it to my 2 12V batteries connected in series and it leveled the voltages in both with 2-3 hours

This guy works as it should.

I have not sued it yet because it has a strong smell out of the box like burnt rubber or plastic. It could be normal and from manufacturing but seems a bit strong. Is that normal?

100% legit they will help you through out the problem easy to communicate, 100% you will be happy costumer i will buy it again for sure all of its product thanks for resolving my problem appreciate it
