yes off the shelf BMS products are available on the aliexpress site. a 4th gen BMS about 160.00us Kevin [email protected]> wrote:

I see that the LTO cells have a nominal cell voltage of 2.3V, which is quite different than the 3.2V nominal voltage for LiFePO4 cells. That means you might have a hard time finding off-the-shelf

A friend of mine with a Tesla sent me this info from a study done. https://electrek.co/2020/02/21/journal-of-energy-storage-studies-ev-owners-manuals-compiles-best-practices-for-batteries/ Talks about

Hello Kevin. I have completed 5 successful 48 v system installations in various vehicle applications. I am using lithium iron phosphate with very positive success. We have upgraded lead to lifepo4 on

I just had a back-and-forth with this company in China.? I'm evaluating different packs for my Electric Yacht 20KW, and got this quote based on this thread... Hi Mr LaCoursiere, Thanks for your?

Use Aliexpress, type lto batteries in the search.

I like it. You can also see your intemecent bags turn color to know when they need to be changed out. Thank you for your help. [email protected]> wrote:

Good point about conformal coating for BMS and other PCBs. To get wires out of my 'power bag', I cut two matching pieces of sheet (PE?) plastic, about the size of my hand. I drilled matching holes for

Thank you I’m learning so much from this site! Someone else said put the larger desiccant bags in with the batteries and change them out periodically. Coosa is e-84 tested and has some r-value.

I don’t see anything about conformal coating of BMS boards in this long response. Heavy conformal coat is the #1 protection mechanism for most automotive, and particularly EV BMS boards for EVs. Of

Thank you. I like the drybag idea but how do you get the cables sealed if you don’t mind me asking? [email protected]> wrote:

Short answer - no. Long answer - I built a 1200Wh LiFePO4 pack for my 6m proa (multihull) sailboat. I was very concerned about water intrusion so I put the battery cells, BMS, a 10A solar charge

You don't dunk an AGM "without consequence". Depending on the conductivity of the water and the charge on the battery, you are pulling the hydrogen out of the water and the chlorine out of the salt.

If the battery is sufficiently sealed so that water does not get inside, and it has a bms / fuse - then it should hopefully not "run away".? Salt water is much more conductive than fresh water.? Not

That’s perhaps the conundrum. Coming ashore sooner or later (cruisers) you’re going to broach your dingy and water will most certainly invade the typical vented battery box. No prob with AGM

Running hard 85 - 90?amps ?only 4 + hours. ?When I back off to 5 knots around 45 -50amps. ? Best regards,Larry Schmitz

Larry: Just curious. What amps are you pulling from your 16S4P, 360Ah battery pack when you're running for those 5 hours?

Excellent point, Phil, and not to mention that ABYC Standards call for ventilation of the battery box or compartment to prevent the concentration of any escaping toxic or flammable gasses. [-tv]

YouTubes can be wonderful entertainment, but I really don't get the connection between someone throwing lithium into a tub of water has to do with this discussion.? The reactivity of lithium with
