Top notch battery. The chargers they sell seem a bit under amperage. Normal amperage for a 100ah battery is at least 20 amps. Unless you have all day to recharge you battery with 15 amps.
About 40% higher price than other brands of heated batteries. I didn't see anything in the teardown that would justify that premium price. But I'm a newbie at this stuff, so I might be completely out to lunch. I sure wish more batteries came with bluetooth.
We have fitted LiFePO4 batteries to power chairs in our workshop. Definitely you feel more power because off a smaller voltage drop when compared to AGM. The 80ah batteries are comparable in capacity to 40ah LiFePO4. This 105ah LiFePO4 is actually almost triple your current installed capacity. And if you live in a below freezing environment, this is the way to go.
@ricardomarcelino8388 Thanks for the info. I typically don't leave home when it gets below freezing. My condition gets progressively worse in cold weather. The video states that the batteries last longer if charged with a 50 amp charge. There is no way I could charge at that rate through my joystick port. 10 amps is my current charger and about all I would be willing to charge at. Is this an issue charging at 10 amps instead of 50? Having 3x the capacity would be great since I have added accessories to my chair like a computer and cameras.
Charging at 10A is perfectly fine. What I was referring to is the battery will degrade faster if you constantly charge it at the maximum rating of 100A vs the recommended rating of 50A.
@@orion_13 as mentioned by @Lithium solar, charging at a lower rate is better, not worse. Take into account that your power chair charge indicator, will not be as accurate as with a "regular battery" as the indicator in the joystick is based on voltage. And because LiFePO4 has a flat charge/discharge voltage curve, you will not be able to use it "as usual" as a reference. So you may see a sudden decrease in voltage near the end of the capacity. Nevertheless, we usually don't see this as a problem, since you are almost tripling the actual capacity, or actually more than that if your battery is not in 100% health any more. Just take that into account. Another topic is if you have a respirator aid or any kind of life support aid attached to the battery, a LiFePO4 BMS battery may cut power supply in given conditions, and for that end use, I would not recommend it. For an accurate state of charge, you may use a shunt, there are several types of these, or as a less effective means, you can consult the battery app, which is less accurate than a shunt, but should be fine.
With a 30 milli-ohm internal resistance (it might be lower but this is the worst case) at 80A recommended discharge limit the voltage at the battery's terminals will fall from nominal 12.8V to 10.4V. That's before any other losses in wiring and switching are considered. At 100A it goes to 9.8V. Nothing wrong with 30 milli-ohm impedance on the battery, but this is why people come unstuck expecting to be able to draw high current out of a single small lithium battery to operate an inverter - the voltage falls to the point where the inverter says 'no more' and turns off.
If they could integrate a charge controller of some sort so I can use one in my dump trailer that would be awesome. I used a battleborn and it just pops the fuse on the truck side because the battery can accept anything the truck can output.
This is not designed to be an engine-starting battery. They do have some batteries rated for cranking though if you check their website. I have not tested any of them.
@@LithiumSolar that's 10.95 years with daily discharge of 80%. My guess is less than 1% of people that use this type of battery will do an 80% DOD daily. In 10 years', we will probably see 2 or 3 different battery types that are better and cheaper. Thank you for all the work you do.
Disappointed that such an expensive battery is using strapping tape rather than a metal cage. Not sure what the additional cost is compared to Ecoworthy and Litime.
I HAVE THE SAME EXACT BMS IN MY CHEAP 140.00 DOLLAR LIFEPO4 BATTERY FROM AMAZON AND ITS CALLED THE MJBSAN AND IT HAS THE SAME EXACT BMS I KNEW IT LOOKED CLOSE BUT YEAH I JUST CHECKED AND ITS THE SAME EXACT ONE
NOPE GO AHEAD AND MESS WITH THE SETTING IF I CAN FIGURE IT OUT AND I NEVER PASSE THE 10th GRADE IM SURE YOU WAY SMARTER PEOPLE CAN FIGURE IT OT LOL NOT HARD JUST WATCH HOW YOUR BATTERY LIKE TO PERFORM AND GO FROM THERE

That is a very well-made battery, but at roughly twice the price of your budget 100ah, 12.8v, LFP batteries, it ought to be!
I was hoping it was going to be something in the $100 to $200 range. Not $350.
Yeah I do feel it is a bit on the pricey side. The Black Friday price seemed much more appealing $297 w/ free shipping.
I know of a blue discovery 12volt 100ah price was $1200 dollars .
I got the 300 amp hour from the same Black Friday sale $913 delivered heatedy
The Epoch 48V server rack battery looks exactly like the RUIXU battery that has been reviewed all over UA-cam.
You're right, it does look identical - hadn't noticed that and I have a Ruxiu lol.
Would you recommend these for a powerchair? I need 2 group 24 12volt. My current gel cell batteries are 12v 80 AH.

Thumbs up 👍 your new work station looks amazing. Giving you some inspiration for your work. Keep it coming. 😊

Victron makes a nice DC-to-DC charger that will solve that problem without buying a whole new battery.
You said that you left the battery hooked up to the charger overnight - is that for balancing the cells?
Yeah I usually leave it plugged in overnight hoping it will do a bit of balancing (if needed) since it's the first charge.
So many batteries to chose from and price is everything but only if it lasts.
all batteries only last so long. they have a cycle life.
thanks

I just acquired 8 brand new ,( made in August ), mb31 eve cells through Epoch Battery for $800 shipped.
Ok?
Can this battery start an 115 kW petrol engine? ie. Is 200 A enough for this?
This is not designed to be an engine-starting battery. They do have some batteries rated for cranking though if you check their website. I have not tested any of them.
Please review the epoch with victron communication and dual purpose. Thank you.
how many cycles is this batteries life span ?
I covered that in the video. It's rated for 4000 cycles at an 80% depth of discharge.

blue discovery lithium
12volt 100ah with Bluetooth price : aprox $1200 , how much is your cost of this battery??
Dope
BT app is cool.
Disappointed that such an expensive battery is using strapping tape rather than a metal cage. Not sure what the additional cost is compared to Ecoworthy and Litime.
It has steel plates on the ends, I was satisfied with that.
Without free shipping this battery is too much it will be close to $450 with sales tax & shipping for a 100AH.
I don't disagree there...
Pricey
super overpriced compared to rest of market
💧. . .
I think the build quality looks really sloppy compared to wattcycle batteries.
What about it looks sloppy?
@@LithiumSolar I think the stick on foam.
First... But who cares.
I care :)

“tesssla” or “Tesla”. These all come down to companies that were late to market and couldn’t get good domain names.
