TalentCell 12V 12Ah Rechargeable Lithium Iron Phosphate Battery Pack

acamus: Purchased kit with battery to supply power for the trail camera. Since fully charging the unit, it has been in operation for two months. Great value, great performance, compared to the same voltage and Amp-hour capacity of the AGM battery it replaced. Hoping for a long life!

rgray107918rgray107918: I would absolutely purchase additional batteries based on customer support.

Phenomenal customer support. I bought two 12V 12aH batteries, and one of them is acting weird. I sent an email to TalenCell through their website and had a reply in less than 24 hours. I am currently engaged in a troubleshooting dialog via email with TalentCell.

I will update this review as the troubleshooting continues.

It should be mentioned that I am using a kill switch, LED, battery monitor, and in line fuses with the battery in question. This battery will provide amperage to a parallel resistor load no problem, but will not power my ham radio transceiver, Icom 706MkIIg. Let's call this battery #2.

The other battery, battery #1, without the added components powers the radio just fine.

Even when I remove the components from battery #2, it will not power the 706.

I have tried several different methods of charging and I still cannot get battery #2 to power the radio. I removed
everything I added to the battery (monitor, switch, LED) and connected it to a bench power supply and two DMM, one to monitor current and one to monitor voltage. The battery...

Stephen WitteStephen Witte: Review of talentcell LF120A1 batteries.

Planned use: cpap machine backpacking

I bought a specially designed charger for LiFePo4 batteries. This is important. The charger is a "CTEK (56-926) LITHIUM US 12 Volt Fully Automatic LiFePO4 Battery Charger", $95, bought from Amazon. It is engineered to provide the right voltage waveforms to correctly charge LiFePo4 batteries. The voltages are just different enough to make a lead acid battery charger worse than useless. With the right charger, the batteries will be fully charged after a couple of full charge and discharge cycles.

In order to have any idea what was going on with these batteries, I also bought a "HiLetgo DC 6.5-100V 0-20A LCD Display Digital Ammeter " for about $12. This little beautiful device would give me the current, voltage, power and total watt hour consumption. This is how I know that these batteries put out 145 wH of energy against a specification of 153 wH. This was close enough for me and about 95% of what was claimed. I know this after testing with a 12 volt to 120 volt converter and running a 60 lamp for two hours. See the pictures of the test rig.

The LiFePo4 batteries were, for about...

Liz: When I first got the battery I didn't use it for a few days and then checked the voltage and it was completely dead. I asked Amazon to replace it, which they did promptly. I checked the new battery and it had a weak charge, so I charged it to full and took the charger off. I noticed that it the voltage would drop off steadily and relatively quick over just a few days without a load. Then I read on another site that LiFePO4 batteries need a heavy charge when initially put in service in order to balance all cells, so I charged the battery for 24 hours. Since then I notice that the battery holds a charge well and no longer drains without being used. While using the battery I find that the 12Ah rating to be a fair rating for the capacity. If you buy this battery, be sure to put an extended charge on it the first time. After that, a normal charge to full capacity should do the trick. I realize now that the first battery issues were probably due to not giving a proper charge right away.
