Nice presentation. I ordered a battery from Bioenno a while back. It turned out the model I wanted was tied up in production for a while, and rather than asking me to wait, Kevin himself offered me a VERY SIGNIFICANT upgrade for free, to get me up and running faster. Stand-up guy, stand up company.
Excellent presentation. Kevin sold me a 12V 12Ah battery and I've used it on road trips, state parks, and now I'm using it (testing) as the power supply for my home UHF/VHF radio.
Thanks, Mike & Kevin. That was very interesting. I was amazed at the broad list of applications that they are involved with and the description of the internal board and how it works. I've been using LiFe batteries in my RC airplanes for some time (Rx, servo power). Of course our batteries do not have internal circuit and we use special chargers with balancing capability. I'm thinking about using one of these for my Ham Radio Portable operations.
Much as they keep your airplanes up in the sky, they will keep your radios running too. Absolutely fantastic batteries. You might need to configure your charger to operate without its balancing feature though. I had to do that with mine.
Awesome! Very interesting presentation! Probably as interesting as my own story with Bioenno :) ! The Bioenno batteries are hard to obtain in the Nordic and Baltic countries of the European Union, no dealers yet. So I wrote straight to the company asking for the info on how could I buy the 12V/ 20Ah pack and immediately got an answer from Kevin himself! The answer actually was " What's your address?". The ordering and paying was quick and easy. And then, a few weeks later I got a parcel at my door with my battery in it! Right on time, for I was finishing my go box and a video on it! My field test of the 12V/20Ah Bioenno just confirm what Kevin said about the duration of ham radio operation on one charge in his presentation. Accordingly to my measurements, my go-box was able to run off this battery for more than 3 hours at nearly full 100W power at a heavy duty cycle ( ~90 percent CW TX, 10 percent RX + a tablet PC) and it only consumed 14 Ah of 20 Ah available! Thanks again for a fine video! 73! Linas LY2H
@@hamradiotube I was charged for shipping around 130 USD , I don't have the papers at hand. One could say a lot, but it depends on the market and on the overal value for money.

As to the value for money, I think the Bioenno, even with the high shipping costs included is a very good deal since it's certainly a very long time investment ( how many years would 2000 cycles make even for an active ham radio user? 10? more? ). :)
This answered a lot of my questions. And is still a valuable video 2 years later. I do have one question. And maybe I missed it.

LiFePO4 batteries can be absolutely abused and they will take just about anything you throw at them. I've seen guys shoot them with a crossbow, overcharge the heck out of them, all kinds of things. I don't think they would work after that but they never explode or catch fire. Super safe.
Brilliant, I've recently asked a lot of questions about this elsewhere on the interweb and the answers have varied from being extremely wrong to haven't a clue. Finally, I can get some decent power for portable operations!
Thanks again Mike for great content. Started following you when you got started a couple years ago, same time i got started, and you have never failed to present informative videos.

I use the 20 amp hour battery with a power-gate to use as a ups system. I also used it with a 150 watt power inverter to power two PA speakers .With my radio I tested for over 6 hours and the PA speakers for there. I don't have any thing to monitor the battery, so I have no clue how much joice I had left. I love this battery and every thing is on with Anderson connecters.
It's certainly amazing how much power you can get out of these batteries.

I know that there are a lot of great Elmers not only on UA-cam but in the real world too. I would encourage anyone who is subject to any kind of hostility to just brush it off and find a different repeater or club or whatever.
This looks like an updated presentation by Kevin, and it is informative just as the last presentation was... I really like my 20 Ah Bioenno LiFePO4 battery.

Good video Mike❗️👍 I am going back and checking out some of your older video since I haven’t been one of your subscribers very long. Looks like you’ve got a lot of good videos posted 73. KV5P
I just bought one of these batteries yesterday from DX Engineering. I charged it up last night. Today I'm going to set it up to run my Yaesu 2600m 2 meter radio in my pickup. My RV has lithium batteries so I'm familiar with them. My question is, how do I know the "state of charge" (percentage of power left} with these since voltage is no indicator? The system in my RV has an indicator in my monitoring system. Is there a way?
What's your call sign and name? LOL! I bought one a few months back, great battery. I had used my sealed lead acid booster pack to power portable and outgrew that real quick. My whole shack is run from a anderson power pole distribution block and I have run everything in my house shack with the bio during power outages. Just unplug the power supply, plug in the battery and I'm on the air.
Wouldn't those battery boosters absolutely destroy lead acid batteries? I love when the power goes out at my house. I immediately go to my radio and marvel at the zero noise floor. Its like I'm at a park, but I'm home. I love it.
If the BMS built into the battery will handle varying inputs, why do I need a special charger (instead of a generic 12-14.4 volt type) to charge it? I would think that as long as I could be certain to restrict the input current, that the BMS would make the battery happy and I'd need one less piece of gear. And could even use a conventional MPPT controller. (Again, within the charge range limits.)
LiFePO4 batteries want a constant current/constant voltage charge. The reason you need a special charger for that type of chemistry is also due to the charging voltage of the cells. They charge up to 3.65v per cell, or 14.6 volts for the pack. Once saturated they will settle to about 13.3~ V. Other chemistries have different charge voltages so while you can technically use even a power supply for your radio to charge it, you will never fully charge it because you aren't going to a high enough voltage. Even LiPo (lithium polymer) batteries charge to a different cell voltage. Lead acid is even lower. The BMS (or pcb) in the Bioenno's protect the cells from over charge, over discharge, over temperature, and balance the cells voltage. I wouldn't say the BMS handles varying inputs. Not sure where you got that from. You will also need a solar charge controller specifically for LiFePO4 if you plan on going that route.
Why do the larger batteries (20A, 30A, etc) use a big gray Powerpole that most hams would simply have to cut off, when the same 45A style PowerPole that the charger uses would still exceed the discharge current of the battery?
I have their 28, 40, 60, and 100 watt solar panels I'm going to review. It hasn't been very sunny here since Memorial Day so I haven't been able to film a proper review yet. Initial tests have given me about 1.3-1.5 amps with the smaller ones and I'm hoping to use one of those with my G90 go box / solar generator. I suspect they will give me a bit more power during the summer as the sun is more overhead.
@@hamradiotube you are very welcome, Mike. I tried so many times to be here when you were live streaming but it never worked because of the different Time Zones we live. I already felt bad because of never making it to one of your life streams. I promise to get better. Happy sunday & stay safe...73's.
Unfortunately I wouldn’t get your hopes up. I don’t really know the answer but I believe it has to do with shipping costs. You can order them but it would cost prob twice as much.
I just switched over my wham-o-can from AGM battery to Bioenno. The AGM battery had such a heavy voltage drop after a while that the radio would shut off when transmitting. I had to change the solar charge controller, but found a small one by Renogy 10 Amp Negative that allows all to fit into the Fat-50 ammo can with my Yaesu FT-8900. So far, the Bioenno is performing as desired. Here is the charge controller I am using. www.amazon.com/gp/product/B07NPDWZJ7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I am using a BLF-1206A battery.
Thats awesome. Your pack is now half the weight with double the battery capacity. Once I discovered LiFePO4, I got rid of the SLA's and never looked back.
You have to calculate it based off how you operate. I go by a 50% duty cycle as I operate primarily portable running pileups. That totally changes the amount of time you can get.
@@hamradiotube Basically what i meant by "wrong" is that the calculation is done on "TX watts" which is missleading. E.g. lets say you have a ft891: That thing draws ~1A at just RX, 7A at 10W TX. So on 50/50 RX/TX @10W a 12AH battery will last for like 2:30h plus/minus. (~5h at 20/80 approx)
@@pulponair No you'd prob get more like 5 hours at 10 watts with a 12ah battery running ssb. A bit less with CW or Digital I suspect. I don't really care about the formulas though. I've got LOTS of actual on air time and I always have a meter in line to monitor my AH's used as you can't go by voltage at all. I've still not depleted my 20ah battery but I ran the 891 for about 4 hours at 90 watts and made 300 contacts. I used 14 amp hours. By that math I was using about 3.5 ah per hour. I would estimate almost 6 hours of use out of the 20ah running full on pileups. I haven't run qrp on that radio in so long I don't have any data to back up the operating time, but it would be pretty long even with a 12ah battery.
@@hamradiotube Glad to hear that it lasts longer than it seems. 300 contacts in 4 hours? That is one contact every 48 seconds, sounds like a hard day ;)

@@hamradiotube Basically what i meant by "wrong" is that the calculation is done on "TX watts" which is missleading. E.g. lets say you have a ft891: That thing draws ~1A at just RX, 7A at 10W TX. So on 50/50 RX/TX @10W a 12AH battery will last for like 2:30h plus/minus. (~5h at 20/80 approx)
@@pulponair No you'd prob get more like 5 hours at 10 watts with a 12ah battery running ssb. A bit less with CW or Digital I suspect. I don't really care about the formulas though. I've got LOTS of actual on air time and I always have a meter in line to monitor my AH's used as you can't go by voltage at all. I've still not depleted my 20ah battery but I ran the 891 for about 4 hours at 90 watts and made 300 contacts. I used 14 amp hours. By that math I was using about 3.5 ah per hour. I would estimate almost 6 hours of use out of the 20ah running full on pileups. I haven't run qrp on that radio in so long I don't have any data to back up the operating time, but it would be pretty long even with a 12ah battery.
@@hamradiotube Glad to hear that it lasts longer than it seems. 300 contacts in 4 hours? That is one contact every 48 seconds, sounds like a hard day ;)
Good presentation, terrible video. Rather see what ur presenting, not some picture of a map
glad you liked the video
