Wholesale 48V 20Ah-500Ah Lifepo4 Battery Energy Storage System

I purchased this battery energy storage system to use in conjunction with a small off-the-grid solar solution. You can find my exhaustive review here . This battery is non-spillable which is great, especially when using for a boat's solar solution like I do. Multiple lifepo4 storage batteries can be paired together in a series, if more power is needed. I felt that this was a very fair price and it's more than enough to keep the LED lighting and other small DC accessories in my boat running. It recharges somewhat quickly with the solar panel too! I highly recommend this battery but keep in mind that UPG sells batteries of other sizes too.

Works as expected so far. During a recent power outage, I discovered my Cyberpower CP1500PFCLCD UPS (now over four years old) was in need of new batteries. The moment the power went out, the UPS sounded the Low battery energy storage system alarm and only provided about 2 minutes of backup power.Something I have always thought of doing when this time came was to replace the two 8Ah batteries with larger ones. After considering dollar per amp hour (and the fact the UPS requires two 12v batteries in series to supply 24v), these 20Ah ExpertPower UFO Energy solar storage batteries were chosen.

Batteries arrived in good condition and a good charge of 12.9 volts. I appreciate the screw down terminals as well. Using 10 AWG stranded wire, I wired the two batteries in series with a small (perhaps 4 inch section), soldering and shrink tubing screw down terminal connectors to the cable. Then to utilize the original CyberPower battery pack's connector, I made-up two more sections of 10 AWG stranded cable (one end having the soldered and shrink tube terminal screw down connectors while the other end having soldered and shrink tube male push on connectors).

The result may not be cosmetically pretty, but it is effective (and hidden in a cabinet along with my VMware server, 24 port POE switch, and cable modem). I will complete the modification (allowing for the UPS front cover to be fully reinstalled) by creating a port on the side of the UPS for the battery energy storage system connector to run through. In the mean time, I have provided pictures of the current configuration.

I was a little concerned about the low price and the packaging they arrived in, but these batteries are awesome. I'm was looking for a battery to power my generator starter and got two for the price of one motorcycle battery. I'm using the extra battery in a small solar battery energy storage system. Very pleased.
