Ensure network and data availability while staying connected at the most critical moments. Smart-UPS with Lithium-ion batteres provides up to 3x the life of VRLA batteries. Pre-installed network managment options and protection from 500VA-3000VA, Smart-UPS Lithium-ion offers a broad range of power options.
The LiFePO4 battery is also non-toxic and safe for the environment since it has no caustic materials or dangerous odors. For comparison, a lithium cobalt oxide battery cell has a nominal voltage of about 3.6 Volts. This results in higher energy capacity but can produce more heat in the electrolyte that causes break down and reduces the capacity.

LiFePO4 batteries are larger and heavier than AGM counterparts. This can be a disadvantage, particularly in applications where space or weight limitations are critical factors. Lower Energy Density: In comparison to some other battery chemistries, LiFePO4 batteries exhibit lower energy density.
I made a successful DIY Lifepo4 12v 32650 batteries to replace the dead lead acid battery of my UPS. Enjoy the video!
For over 10 years I''ve used APC Smart-UPS 1500. I very quickly replaced the built in batteries with: (2) Series 49 (aka H8) Lead Acid & AGM batteries. (4) 6V 175Ah Flooded Deep Cell batteries. (2) 4D Flooded batteries. (2) 8D Flooded & AGM batteries. They typically didn''t last long, because they got cooked by the built-in charging voltages.
Regular lead acid batteries only last 2-3 years on standby in a Uninterrupted Power System (UPS), time to upgrade the batteries to longer lasting Lithium Iro...

I know I am late to the Party, but I am in need of replacing batteries on my SRM3000VA UPS, and thinking of converting it by buying premade 12V LiFePo4 Batteries. My Question is the 3000VA is rated on the Battery …
I have an APC 1400 UPS that has 4 SLA batteries that I want to replace with 7S LifePO4 battery along with BMS. After extensive research on the APC UPS, the cutoff voltage of …
I have a surprising large number of these -- three in older UPS systems, two used as the backup power source in a couple security system boxes, one as backup to FIOS, etc. It would make sense to replace the AGM batteries with a LiFEPO4, getting the benefit of longer life and more power density.
I started a small project for myself to upgrade my older APC Smart-UPS 1500 (SUA1500i) from AGM SLA batteries to LiFePO4 batteries with advanced BMS. Normally UPS units …
Ups float is 3.45v per cell. it should give me 2-3000 cycles or 5 years of life for the battery pack. I have made 12,24,36 & 48v battery packs for ups using this method. > 20 packs for family and friends and no issues yet. Now Im entering Car starting Batteries with same cells. Going great, have 4 cars running, with 0 issues.
They have low voltage disconnects and internal BMS, and only weigh about 20% of what the original battery weighs, which is a huge bonus. So I bought a LiFePo4 replacement for the car battery, mostly to prevent having to replace batteries so often because these things are supposed to have an 8 year life. Fast forward one year later, battery''s shot.
Lithium-ion batteries simply store more power than their traditional sealed lead-acid counterparts. Your UPS will be run more efficiently when making the switch to lithium-ion. Lithium-ion batteries can use about 95% of stored energy from a single charge, while a lead-acid battery will only use about 80-85% of stored energy. 5.
Charging voltage from the charge controller. A lead-acid battery has a 3 stage charging profile, while a lithium battery has only one. Bulk, absorption, float, and equalization for a lead acid battery. The voltage also differs between the two. That''s why you need a charge controller that can be manually programmed or changed to a lithium …
