EPEVER 10A Solar Charge Controller Battery Solar Panel MPPT with LCD Display for 24/36/48/60/72 V Battery MPPT 7210A

This charge controller is for e-bike and scooter batteries charging on solar panels. It has a 10 amp limit which would charge a 100-amp hour Lithium battery at 0.1C (one tenth battery capacity) but, most e-bike and scooter batteries are smaller. Connect the solar panels first since most e-bike batteries have a charge port that has a diode that prevents power out. The screen comes on and you can set the voltage and amperage for the battery - the numbers to put in are the output numbers of your AC charger. My charger says 54.6 volts at 2 amps (for a 48V battery) so that is what I put into the settings. You can save the settings in the "data" memory which has 20 spots to store different settings. This controller is for solar panels, but you could connect a battery to the solar inputs and the controller will charge your e-bike battery. A hint about the solar input - you can have more solar panels than needed to charge the battery. The wattage for charging my 48-volt battery is 109.2 watts but I will have 200 or 300 watts of solar panels to cover cloudy weather, the controller will charge the battery just like the AC charger. One other hint - there are screwdriver holes in the top of the unit so you can connect wires without taking it apart.

expect this item to fail or catch fire. Cheap for a reason. Required a loud fan. Retuned for a better product as I was installing it in a camper, and didn't want it burning to the ground.

works great, charges fast, makes a lot of noise

All metal construction, well made, mounted onto a 1/4 inch steel plate for additional heat sink...

Love this device

This is not an mppt charge controller. I did fall in love with the awesome display which shows voltage, watts and amps but that would be the only 5 star feature. This is a dc-dc boost module encased in aluminum with the most irritating fan in the world. After purchasing 2 of them and testing for weeks I discovered that the conversion efficiency is somewhere around 65% when charging a 28V 7s battery bank . I have four 100 watt panels in parallel at 22V (Voc) and 20 amps combined. With 2 panels connected to each controller they only draw about 6 to 8 amps each at about 300 watts combined. A decent pwm controller can do better. I do love that display though...

I use it to charge a 63 volt li ion pack

#1 does not regulate voltage to battery.#2 loses settings if power is lost.I wish I would have tested it out as soon as I got it.Can't return it now.
