## Description

Product description Professional Lithium Iron Phosphate Battery Manufacturer 12v 15ah lithium iron phosphate batteries are made of brand new A-grade batteries, eliminating disassembled cells and B-grade cells. The operating current of 12V 15Ah battery is 8A, and the maximum instantaneous current is 40A(5 seconds). It has a service life of over 3,000 cycles, making it a reliable choice for all your energy storage needs. The built-in BMS (Battery Management System) prevents overcharging, over-discharging, over-current and short-circuiting, ensuring the safety and reliability of the battery. Multiple charging options Support Li-FePO4 battery charger, lead-acid battery charger, solar panel + MPPT charging, max. 5A fast charging. If single battery charging, charging voltage is 14.6V, two batteries in series charging, charging voltage is 29.2V. APPLIANCE

Review: A good battery but not as a replacement for an AGM in my Cyberpower UPS - well maybe is - 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.
Review: Take and hold charge well, nice lightweight replacements for lead acid - So far, so good. Hope they outlast traditional lead acid in my UPS.

### ⭐⭐⭐⭐⭐ Plenty of power, moderate weight.
*by A***R on November 14, 2025*

I have purchased 4 of these at different times for powering homemade boomboxes. They deliver excellent power and run a long time for the application I’m using them in. Most of these builds have been in a rolling case about carry on sized with 400-500 watt amplifiers in them. Highly recommend!
