  1. Yeah. They are pretty and convenient but are they THAT pretty and convenient.
  2. Aluminum has very good conductivity but less conductivity. You will find voltage loss charts for both copper and aluminum. Copper loses less voltage. It may not matter for you, but just look at the numbers and be aware. Also when you join aluminum and copper wires together it causes a chemical reaction and deterioration over time so use ox guard or similar product on any union.
  3. Yes. I would check if you inverter/charger gives specification. My magnum called for 4/0.
  4. Go for it Glenn. This is for lifepo4 but read it through as it may give you some thoughts on design issues. https://marinehowto.com/lifepo4-batteries-on-boats/
  5. Watching. Interested also
  6. All of the fires get categorized as lithium caused which is the problem. It is not apples to apples. Clearly LiFePo4 is the safest but there are many RVers successfully using Volt, leaf and Tesla batteries. If you are DIY you do need to know your battery chemistry and charge parameters. As you say both of the above are probably charger caused problems. Do not slap a lead acid charger on and expect everything to be okay. It is best to oversize the pack and not push them all the way to the top when charging. Unlike lead acid they do not need to be topped off.
  7. You should watch the battery section on the you tube called "beginning this morning".He does a large Nissan leaf cell installation.
  8. How Many amp hours are you thinking of getting? / /
  9. Looks like lg makes the leaf battery also so they could be either.
  10. These are the specs I see on a volt cell. See how they match up. Cell type Laminate type Cathode material LiMn2O4 with LiNiO2 Anode material Graphite Rated capacity (0.3C) 17 Ah Average voltage 3.8 VDC Maximum Voltage 4.2VDC Minimum Voltage 3.0VDC
  11. If you are looking at the BMS make sure it can handle both the charge and discharge amperage you will be throwing at it. Sometimes they just give you the discharge amp.
  12. Looks like LG makes the volt battery and those look exactly like volt cells so I bet that is what you are dealing with. From what I have read the volt battery charging range does not match up well for a 12 volt pack but does for a 24 or 48 volt. c He does a Chevy Volt battery install. If jcussen has been dealing with him i definetly would be interested in learning more.
  13. Well that is a very low price. I would want to know how much they have been used (they are new?) and their exact chemistry. Did they actually do a capacity test or is that the original rating. Lifepo4 is the safest of the chemistries but more expensive. Once you know the actual chemistry you can determine the true voltage operating range and whether it is compatible with your equipment.
