This small lithium battery has performed very well through six fishing outings supplying Power to my Humminbird Helix 5 fish finder. It holds the charge through 6 hours on the water. I highly recommend this light weight battery.

Although slightly shorter in height than original batteries, work like a charm. I have replaced the batteries in a 90's fold n go power scooter with these amazing little gems. Can and does still use its original charger, battery pack is now half the weight of what it used to be, and packs quite the punch. Installed very easily by swapping everything over to the new batteries, fully charged in very little time and scooter that had been sitting for years was back on the road.

Battery worked great at the start, we followed charging instructions but did not last more than a month. Now it won’t hold a charge. It’s a dead battery that got very little use out of it. However, customer service was great, warranty was honored and a new one was sent out. I will provide an update on the next battery to see if this one lasts longer.

Due to frequent pwr outage in S.Cal I was looking for replacement batteries for two UPS units. These APC-brand units are over 10 yrs old but are working like champs. The lead acid batteries have been replaced twice and each last roughly 4-5yrs. Initially I was not sure about the charging compatibility b/w Lead Acid and LiFePO, but after reading other ppl's reviews and internet posts, I ordered two battries and surely enough these two units were put to work and test in realtime. Happy to see at one long outage they lasted twice longer (from 3 hrs to 6 hrs) on a relatively low load of 110-130Watts. The battery is fully charged within 1hrs when power is back. It costed a little more than lead one but for the extra $ it's worth. Beside it's half the weight of lead acid ones, when you get older you will appreciate the weight difference. I used LiFePO in RC-controlled airplanes so I love these powerful but lighter one. Seller is very responsive to my concern and timely addressed my inquiry. Highly recommended.

I’d recommend against usage for “legacy” UPS lead acid battery replacement, specifically the common case of quantity 4 or 2 battery systems. These usually are setup with the batteries in series (4x12v = 48v, 2x12v=24v). You are likely better off throwing the legacy lead acid battery UPS away, and buying a lifepo4 based UPS. Even the Lifepo4 portable batteries like the power 1000 have UPS capability. The ups devices that start with a lifepo4 energy source usually have passive and active cooling for the battery array, in addition to the inverter components. There are a few problems with using these in a legacy lead acid battery UPS: 1. The continuous output current is far lower than lead acid batteries. The typical Lifepo4 compatible battery option is rated at 10amp continuous. So, in a 4 battery series system, you’ll get at most about 135w continuous output per battery - so about 500watt max. You won’t get anything near the potential needed in common 1000w, 1500w, and 2000w ups. 2. The BMS present in the lifepo4 batteries generally needs at least exposed passive cooling, or even active cooling. These are enclosed package batteries, so cooling is limited at best. 3. With 4 12v lifepo4 batteries in series, you’d basically need another BMS to manage the 4 batteries, or the discharge and charge levels between batteries becomes imbalanced. 4. The charging circuit will not fully charge lifepo4 batteries, in most cases. Lead acid vs. lifepo4 have different max voltage levels. 5. The legacy ups doesn’t know the proper estimated runtime or charge level of lifepo4 batteries. This is a relatively minor issue compared to above. Technically, a 48v lifepo4 pack that fits most UPS battery compartments could be built to handle several of the issues above. As an experiment, I fully charged up 4 of these individually outside a UPS, then installed them in the ups. Verified the output of the pack was approx 55.8v. The charge/discharge circuit ”popped” with the telltale electronics burning smell, with smoke, when a 200w load AC power fail test was triggered. These batteries may be ok for some cases, like the single battery backup common to home alarm system panels.

This is the first battery of this type that I have used. I am still learning about them. So far performance has been good & I have had no problems. I am running a trolling motor & a power inverter with it. My only concern is that very little information is listed about the BMS. This battery lacks certain bells & whistles that can be found on more expensive batteries, like a state of charge indicator or blue tooth communication, but the price was great. Update 2/7/24 - I have now had this for about half a year. I have only gone through about a dozen charge/discharge cycles. I recently did 3 full range cycles in a row using a roughly 50-amp load to drag it down to empty (a little less than 11v) & then charged it back up to full at about a 30-amp rate using a charger specified for this chemistry. The last charge showed 96 amp hours accepted in that single charge cycle before the automatic charger declared the battery full & shut itself off. 96% of specified new capacity after half a year sounds pretty good to me. Unfortunately I did not do a similar test when the battery was new. The battery sat with 100% charge for most of the last 4 months, which is not supposed to be good for this type of battery.

I have used this battery a lot with my outside portable equipment. It has stood up well for field work. Charges easily and deliverers consistent volts and amps. I wouldn't hesitate to replace it with the same battery when I need to.
