Electronics-Salon Low Voltage Disconnect Module LVD, 24V 30A, Protect/Prolong Battery Life.

I ordered this to do LVD for a mower that pulls 20-30 amps. I haven't tested it yet. Here is a cropped pic of the high current carrying pooled solder. One area towards the left contact looks narrow/weak. Any bets? Adding this pic because the seller did not include one of the backside.Update: I ran it for a half-hour without a failure. Grass wasn't long enough yet to push towards 30amps, however. Bumped up 1 star since it didn't fail right off.Update2: After several more uses it is holding up, but still haven't had/made opportunity to load it right up to 30A continuous.Update3: Unit made it through weekly usage through the whole season and Fall cleanup. Calling it good.

My kids frequently use my older electric mower with SLA batteries. Despite my adding an LED to indicate when to stop mowing due to battery state, they are accustomed to gas mowers and sometimes take my batteries to near 100% discharge. Adding the LVD, which is much cheaper than even SLA batteries, allows me to "enforce" my instructions on when to stop mowing. Easy to use. Easier if you have a wiring schematic of your device.

I have made reviews on this before. It works well.

It works OK and as specified. I just wish it had more voltages selections than it has for the cut-off and reconnect. At 24.2 and 25.6 you are cutting out after you have drained below 50% and reconnecting at greater than 100% charge. If you use any other set of switches on the cut out side you may be damaging your battery by excessive drain. By 20 volts the lowest cut off your batteries are basically at 0%. Not good for lead acids. I installed a large diode in series with this with a forward voltage drop of 0.6 Volts so that cut off happens closer to 75% of battery life.

I have used the 12V version for a year, and the 24V version as of a month ago, on small off-grid solar + battery systems. Straightforward to install and configure, and no failures so far. LED provides easy feedback on status of circuit (green when enabled, red when disconnected. Recommend using standoffs when mounting since there are components on both sides of the PCB, and mounting in vertical position to support air flow across components.

Great alternative to having a BMS which you cannot test and check for accuracy on the bottom end of charge cycle. this product just works. Install this unit in between the lithium battery and the load/charge and you are basically done. Unit will disconnect once the battery reaches the specified low voltage and cuts the current so you cannot damage the battery. Great Idea and it works great.

Used it as over discharge protection for a lithium ion battery. Works very well.

Works as expected. Automatically shuts off at the selected voltage.
