 |
|
For anyone who is curious as to how a Battle Born lithium battery is put together here is a video of someone tearing one apart.https://www.youtube.com/watch?v=G5E30u-66VI
If you search a bit more on Youtube you can find a couple of more videos of him tearing down a cheaper Riuxu battery as well.
Cheers

Will is a great YouTub artist. His video is a breath of fresh air, he is always so excited to share and the content is good stuff. Here is another shot at his YouTube library:https://www.youtube.com/user/errolprowse/videos

Ron,
Thanks for finding the video. That's guts ball to cut up a $1000 battery! I had looked into the various LiFePO4 batteries, and went with Battleborn. I found their technicians to be extremely helpful, and very meticulous. When I added a second 100 amp hour battery, they wanted the serial number of my first battery, so they could program my inverter/charger specifically for those two batteries.
As for temp sensor--Yes, it would be ideal for a temperature sensor on each cell--but I believe that the one which is there, at the top, is where it is most important. On my unit, I have a 2nd temp sensor from the inverter charger mounted on the negative post of one of the batteries, and there is a 3rd temp sensor inside of the inverter charger.
Solid state batteries may be the future--I don't know...but they are currently costly: | Quote: | | 20 Ah solid-state battery cell would cost US$100,000, and a high-range electric car would require 800 to 1,000 of such cells |
.
The cost of LeFePO4 are slowly coming down. It may be a long time if never when they equal the costs of AGM. But they are a lot better for a house bank.

WOW SOLID STATE BATTERIES!
I have pondered re powering our C-Dory 22 with electric motors and cells from used Prius or Leaf cars when the time comes.
Does anyone have any information or links on a C-Dory re powered with electric power?
thanks for all the great stuff you folks come up with.

Never seen someone so excited about batteries...

Does anyone use the Battle Born Batteries? If so how many and what kind of results do you get? I love to have battery that I could run a small microwav for short time to heat meals up.

Yes, see my post above. The cost for a good inverter charger and batteries will be in the $4,000 range. We cook with induction burner, run a microwave, and keep a chest type freezer and chest type refrigerator cold off the 200 amp hour battery bank.
You can do the same thing for a lot less--but there are some down sides to conventional batteries. 4 group 31 battery (110 amp hour each), will also give about 200 amp hours usable. Weight of these will be about 320 # vs 60# for LI, space will be twice as much. Number of cycles will be somewhat limited on the AGM or Lead acid batteries, vs 3,000 to 5,000 full cycles for Li. Cost for FLA will be less than $400 for generic group 31's. AGMs will cost in the 2 to 3x as much as flooded lead acid. (so $600 to $800). Some premium brands may be more. another option is golf carts--220 amp hour x 4 in series parallel.
The Li battery takes a special charger, and will not charge properly directly off the outboard. A battery to battery charger is necessary. A small bank (200 amps) is probably not good for starting an outboard, so you will still need a lead acid for start.
Unless you have a very comprehensive knowledge of battery systems, I would advise against using Li batteries--there is a lot of power, and a mistake in wiring or circuitry, might end up with a short circuit and damage to batteries, boat or person.
You can decide if you want to use a modified sine wave inverter (probably not work with induction burner, but will--reduced efficiency and noise, reduced life of microwave--I have used both types. Current is PSW. I prefer Magnum, Master Volt or Victron Pure Sine Wave inverters/chargers. Victron is one which has specific profile for Li batteries. |

And therein, lies the crux of the issue for me (beside overall cost). I'm not an electrical engineer. Although, I did stay at a Holiday Inn once.  |

I just ordered a 555 amp-hour LiFePO4 battery from Lithionics for our motorhome. External BMS. I have just finished installing 1520 watts of solar on the motorhome. We will be mostly boondocking for 100 days this winter. Depending on how this experiment goes I may replace the house batteries on Discovery with LiFePO4 next spring.
