LiTime 48V Battery Equalizer, Active Balancer for 24V/36V/48V Bank, Supports for LiFePO4, Lead Acid, Gel, FLA, SLA Battery, Perfect for Home, RV, Solar, Trolling Motor, Off Grid

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.

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

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

Works great

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

Works very well. Helps keep them equal.

I bought this equalizer to leave installed on my battery string. It appears to have failed within 6 weeks and would cause my battery voltages to drop very quickly and lock out the BMS. Eventually things would reset after I broke the string and charged the batteries on their own. Everything has been fine since I removed the equalizer. I like the idea and I have no idea if I just got a bad unit or if it there was something wrong with my application. I did email with LiTime tech support and they seemed to indicate my unit failed but they didn't offer a replacement or any troubleshooting steps. LiTime has otherwise great to deal with so not sure what happened here.

Perfecto

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
