## Customer Reviews

### ⭐⭐⭐⭐⭐ Great capacity, perfect for power outages or off grid power
*by D***P on April 29, 2025*

Purchased to use as a trolling motor battery, but ended up using during a power outage and it worked great. Connected a 300 Watt inverter and was able to run our TV, soundbar, and DVD player for a couple of hours with no signs of running out of charge! Recharges just fine using a standard automotive 12V trickle charger. No need to buy a special LiFePO4 charger.

### ⭐⭐⭐⭐⭐ Fairly easy conversion for older APC power supplies (UPS)
*by S***L on March 14, 2025*

If you are looking to replace the SLA (Sealed Lead Acid) batteries that are normally used in an APC UPS (Uninterruptible Power Supply), I can confirm the 12V 20aH lithium batteries will fit both the APC 1250 Smart-UPS and the APC 1500 Smart-UPS supplies. These are the somewhat older models that sit on the floor (not rack mounted). Putting the two batteries into the unit is a *tight* fit -- I had to actually lightly slap them down into the enclosure -- but you can do so and fit the cover on with the retaining screws. The inline fuse that comes with the UPS will not fit on the top of the LiFePO4 battery -- be prepared to either A) create a shunt to bypass the fuse or B) make up some longer wires that can route the fuse away from the top of the batteries. The batteries I ordered from Amazon came with mounting bolts that fit the battery terminals.All in all, it's a pretty basic conversion. Lithium batteries are far superior to the lead-acid variety and will last MUCH longer. I was only getting 3-ish years out of a set of SLA batteries whereas I can expect 8-10 years+ from these lithium replacements. A bonus in this situation is the original SLA batteries were rated at 18ah where the lithium are 20ah so I should get slightly better runtime during a power outage. Good luck with your conversion!

### ⭐⭐⭐⭐⭐ A good battery but not as a replacement for an AGM in my Cyberpower UPS - well maybe is
*by M***L on October 19, 2024*

I bought 2 BOTKU LIFEPO4 12.8V 10AH 128WH for my Cyberpower cp1500pfclcd.Wanted to see if LIFEPO4 battery would work.I fully charged the batteries on a separate charger to 13.5v (at rest).Ran the UPS at about 100W and it lasted 110 minutes until shutdown - 11.5v at rest (Meaning ~5% power left in the batteries). I let the UPS fully charge them and it stopped at 13.0v. Good to AGM but not high enough for LIFEPO4. Less than 40% of the capacity.I put the same load on and only got 15-16 minutes run time (when charged by the UPS).Cyberpower website say that I should get 66 minutes on AGM with 100watt load.The LIFEPO4 batteries worked well. Basically twice the run time of an AGM. Probably great news for many other uses. Its my UPS that is not compatible. I gambled it could be a replacement. Was wrong. But great batteries.Update a week later: good news. After letting the LIFEPO4 battery in the UPS a few days, the residual voltage began to climb by about 0.1V per day, to stabilize at 13.5V. Well, at that voltage level, the LIFEPO4 is fully charged. Ran for 100 minutes with ~100watt load. Will the trickle charge of the UPS eventually damage the battery? Time will tell. Even if life cycles are cut in half, or the reserve is reduced, is still better/cheaper than AGM type. And the UPS cuts off while the battery still has a 5-10% left due to the difference in voltage between AGM and lifepo4. This is good as the BMS does not lock the battery for being too discharged.
