12V 400Ah Redodo Lithium Iron Phosphate (LiFePO4) Battery

Mel BeckmanMel Beckman: I bought two of these to extend the life of our access control system during an outage, coupled with a 10A LiFePo4 charger. These batteries successfully powered the access controls, which draw 3A at 12V continuously, and 10A intermittently when triggering electric door strikes, for four days without utility power. The combo fits perfectly in a commonly available fiberglass enclosure, mounted above the ceiling. I also added a 12V round voltmeter to show the battery status on the outside of the case, and a Bluetooth battery monitor to let me check status without going into the ceiling.

Mark: I highly recommend the Redodo brand for LiFePO4 batteries. First off, this is neither the cheapest battery, nor one of the more expensive brands. I know a lot of people get all excited paying 2-3 times as much for a Bioenno battery since that's what all the other hams are buying, but I am not one of them. This battery seems to be pretty good so far as far as runtime and capacity. I had ordered a different brand battery first based on good reviews, but quickly sold it when I realized that for the weight of the battery there was no way it was rated accurately (too light to be a 50AH LiFePO4 battery). This one is at least a little heavier, so more likely to be a good battery. No issues with the charge controller, or heat issues. It takes a while to charge once drained, so that is also a good indicator of its capacity. Once charged, it seems to hold a charge well if not used for a while. I use this for powering and recharging devices and powering lights or fans when camping, and for Amateur (HAM) radio, both as a mobile power source for POTA, and as a backup for power outages at home. I personally use and recommend the NOCO brand chargers with this battery, and they work great. The...

Keifer Hendry: I bought two of the 12v 100Ah to replace the lead acid batteries in my floor scrubber, and they worked perfectly right out of the boxes. arrived faster than expected and the customer service has been amazing. when you using more than one at a time make sure to follow the well-written instructions for proper first-time charging and connection for series/parallel hook-up. I will definitely be buying more when the opportunity presents itself.

Georgina Irene Macdonnell: I received my delivery 2 days early well packed alongside an email from the seller. It will be going in my little vintage trailer to power a small solar build. I have not tested it yet but I’m confident with the reviews on this product. I’ll update once I’ve tested and installed. Great price on this battery for entry into the solar world.

Amazon Customer: It holds charge longer and weighs 5 times less. I used it on a trolling motor and it lasted for hours of moderate-speed trolling. Worth the money. I used to have a 100Ah marine battery. It weighed 60 lbs, took forever to charge and did not last as long. Lithium is the way to go.

Scott Meister: 2 parts to this review. The short version first (the TL;DR), then the detailed review later. (Oh, My GOD....please stop talking!!)

I bought this 50Ah battery specifically because of the 3.2 volt cells inside, wired in series for 12.8 volts. They're tough, built like a tank & last for many years. Off-grid cabins use these cells, only larger. It doesn't have the silver-ish colored battery packs (like a cellphone does) or the 18650 cells clumped together, like portable power stations & similar products & other 12 volt batteries do. Yes, I know those are just Lithium & not Lithium Iron Phosphate. Big difference there. You really DO get what you pay for here! Good Grade A automotive cells with a BMS all in one package. It arrived here with 13.18 volts but couldn't test the amperage as my multimeter only goes to 10 amps. So I hooked it up to the charge controller, plugged in the panel & it took 380 watt hours to reach absorb mode (14.2 volts) For 2 hours it absorbed, then switched to float & the voltage dropped S L O W L Y....to 13.5. Full charge! Only took around 7 hours to reach absorb.. So yes, please charge (a LiFePO4 charger ONLY!) this fully before...

fm: After spending time looking for a replacement for my RV I decided Redodo was the best option. The battery came well packaged which was good as delivery driver decided to place it on its side. Box was damaged from this but the battery was so well packaged it was perfect. The instructions are really good with a simple quick start card and a larger manual for more detail. They send two sets of terminal screws which is nice to have in case you loose one. The one thing I did not expect was the size
this battery is about the size of a 31 series AGM. What is have now is a 27 size so battery box will need to go. I do see Redodo now has the same amp battery but in a mini size that would have fit. Even with the larger size this battery is so much lighter. Easily half the weight of my AGM battery which is good for us older guys. Checking the battery and it was about 50% charged at delivery. Once I charged it to 100% I decided to try it out. For my needs I am looking at being able to run a fan, water pump and lights in our RV with occasional 110 volt items using inverter. I connected a 1000 watt inverter and ran a house fan for 3 1/2 hours and only lost 10% which is perfect for my needs....

Aidon M.: This battery arrived faster than the predicted date and packaged in abs plastic sheath. I hate basic styrofoam, so this was nice. opening the box was fun, there is a wonderful information book and two sets of battery terminals as well as insulator caps. the book has all kinds of information consolidated and its easy to understand.
Unlike some smaller lifepo4 batteries, this battery has the posts oriented similar to lead acid/agm etc, positive on left, negative on right. Both are clearly marked.

i got a 100ah battery. I dont know what the peak output is, but it is not quite as simple as 100a * 12.8v.

**i updated my review to say i was unable to power a 743watt sump pump or a 1001watt kettle, pretty much anything under 500 watts with this battery. I suspected the bms was low as that is a thing with some batteries. I am relieved and pleased to share it turns out my grounding wire had damage i was unaware of. I repaired this and the battery is able to power everything i throw at it. I believe this is a limitation of my inverter. I have two pure sine inverters, one needs a ground the other is advertised not needing an earth ground, upon testing that one it runs...
