2 Pack GrenerPower 12V 100Ah Mini LiFePO4 Battery with Small Size & Light Weight, Built-in 100A BMS, Max.1280Wh Energy with 4000-15000 Cycles &10 Years Lifetime for Trolling Motor, RV, Camping, Solar

I recently purchased two GrenerPower 12V 100Ah Mini LiFePO4 Batteries. My plan is to use these as expansion batteries in either 12V or 24V configuration for my various power stations. I will admit, I was slightly hesitant about making this purchase, as this was my first experience with GrenerPower and the "Mini" battery format. After making the purchase, I'm very happy with my decision.The batteries were shipped quickly, well packaged and arrived in perfect condition. Overall construction is first rate, easily equal to the more established brand I have been using in my DIY builds. The small size and weight is amazing and the convenient carry handles fold flush with the top when not in use.Upon receiving the batteries they were immediately charged to 100%. The next morning each battery was connected to an inverter and discharge at a 60 Ah rate for 90 minutes, via a 700W space heater. At the end of this test the measured battery voltage was 12.8V, indicating at least 10% SOC for a LifePO4 battery. Sorry, unlike online reviewers, I paid for these, so a 90% discharge test is all you get. However, I have no doubt they would meet their 100 Ah rating. After discharging, both batteries were recharged at 20 Amps via solar without issue.In conclusion, I really like these batteries, they are small, light, well constructed and perform to spec. At their current price point, they may be the best bargain in the LifePO4 space.

Work great for kayak

When it comes to these MINI 100ah LIFEPO4 batteries, I just love them! This one by GRENER Power was the HIGHEST battery capacity I have tested so far at 106.5ah. This means they are excellent cells and balanced perfectly. What an excellent purchase. These MINIs are very capable of providing a lot of power, in a small compact form factor. I used this one to make a HUGE 100,000mah 12v battery bank to keep all my small electronics charged up on the go or in a power outage.It comes with nice instructions and spec sheet so you know all the parameters to set your chargers/inverters to. You get extra terminal bolts, and a set of terminal covers. The built in handles are a nice touch, making this easy to use a portable system. Check out GRENER's line of chargers for more high quality equipment.I will be buying more of their batteries!! Next will be the 200ah.

I got 4 of the mini size to go in my motorhome. So far they are working great.

I love the size of this battery. I haven’t had it long but it has been working great so far.

Great for my quantum wheelchair went from charging daily to once every ten days thank you lithium why these arent included with the chair proves the makers incompetance and the lies they tell when they say lithium is not compatible as it is and its actually safer than agm lead dead old technology

The media could not be loaded. Just contacted the seller since the 30 day returns has just passed.put 2 of these in a power chair and have only charged 2 times; once before install and then once to top off a few days later after install.bought a lifepo4 charger for that purpose.after the last full charge the battery indicator on my chair went from 8 lights to half and then 2 within moments.this all happened without going any farther than 10 feet.definitely a faulty battery.i have had this problem before but only after 2 years of use....i just got these....hopefully i hear from the supplier asap....my chair is my mobility and i spent $400+ for lifepo4 over absorbent glass mat gel batteries at half the cost....which lasted 3 years....UPDATE: Someone contacted me 4 months later (reported in August then contacted in December) and sent me replacement batteries....and not to use them in a power chair that originally had 55ah SLA batteries....so i won't....yet why are they designed to mimic the 55ah NF-22 battery all the way down to the exact dimensions?

I bought these to replace a couple standard 35ah deep cycle lead acid batteries. They are considerably larger. However, they weigh only as much as the smaller batteries and it would take almost 3 of the 35ah lead acid batteries to provide the same power/longevity of charge so the weight savings is considerable. I was quite disappointed to read through the product manual and discover that I could understand very little of it. It does state that if you have a charger, it should be set on the "LiFePO4" setting. I see no such setting on any of the 4 battery chargers in the garage/shop. If you don't have this setting, you can use a charger set at 20A@20 degrees centigrade. I don't know about you, but I don't either control the charging amperage of my chargers, nor do I know precisely what their charge current actually is. Is this a critical issue? Is there a fire or explosion danger if lithium batteries are charged at an incorrect rate/voltage? Will it ruin them and deep six $400.00 of my money? I have no idea and the manual doesn't explain that. The manual says max continuous charge current is 100A@ 20 degrees centigrade. Recommended charge voltage 14.6 maximum. Cell Balance 3.6V 50mA. High voltage disconnect 15.4V (3.85V/Cell) None of that tells me anything practical. The rest of the material in the manual ranges from practical to highly technical, so here I sit with 2 new batteries for the trolling motor and I'll have to call their tech support to find out what the deuces to do with them. They may be superb batteries, but I have no way of telling if I can even charge them without adding a 5th battery charger to the collection. I'd suggest buying something else unless your background in the electrical field is considerably better than mine or until they send a far more practical manual with the batteries.
