not yet 100% .. but .. For anyone who has one of those OEM BMS 12s boards , and wants to put it to some use. Sense they come 'included' with the $265 for 1.1kwh LTO module .. it's not a bad deal .. battery cells and cell level voltage monitoring...

FYI A little bit of progress with 1st gen Honda Insighter's using them for PHEV conversions. https://www.insightcentral.net/threads/honda-fit-lto-bms-discussion.125085/ Some BMS board swapping is available if you still want / need non-duplicates.

As requested .. Attached are some pics of the two 24s kits .. and the initial dry fit of the two of them into the modified 2000 Honda Insight IMA battery case .. Will be adding aluminum fins between cells .. which will fill the remaining side to side gap in case. Project is not yet 100%...

"May" does not = will "May" does not = promise to Tomorrow I "may" offer someone a PB&J sandwich. That does not mean I will ... that is not me offering the sandwich. If I don't offer the sandwich that still completely fits with what I said I "may" do. I think this approach of yours is counter...

1st Got my two recent 24s kits a little while ago .. :mrgreen: ... absolutely beautiful .. coodoos/props. :mrgreen: - - - - - What are others' thoughts on folding the battery tab around to increase the surface area in contact between the two tabs? A bit of added hassle and complication ...

As mentioned on the other thread .. the initial 2 characters are always SH .. the 3rd character has only been seen as one of 4 options ... A , B , C , D SHA SHB SHC SHD

Keeping in line with the code from the other 56 cells I have ... and other cell serial #s I've seen floating around the web ... using the above as an example. My guesses are bellow ?? but they are just guesses. SH = Location code of production A = the quarter of the year ... all the cells...

No ... $ to high , but the idea has some appeal. The mid-drive would be a nice option to remove the double complexity of having the motor in the loopwheel itself ... sadly I don't have funds to burn either... just a thought exercise for fun.

Although I agree with the concept of low practicality ... introducing other problems ... etc. To answer the question of 'why' ... #1 Because I was curious I don't see why not ask , talk , or think about it ?? #2 Compound benefit -- Niche The 'Loopwheel' concept can be added for additional...

I did a quick search and didn't notice relevant hits. Does anyone have any experience or thought on combining the principle of the Loopwheel with a small Hub motor ? - - - - - - - My first thought ... Aside from the added complexity and cost (of course) ... is that , it should be a viable...

Fair enough. Note. Bellow Is not trying to convince anyone of anything , nor criticize anything nor anyone ... Just explaining myself a bit is all. For an equal Volume, yes. It varies of course for different Alloys , but Here is a crude example I got years ago. By weight Aluminum is more...

Out of curiosity. Have you yet ( or ever intend to later ) test/quantify how much of a difference in conductivity this will make?

Just sharing / passing along some testing data. One aspect that seemed interesting to me ... is the minimum sustained / trickle current rate for the A123 20Ah cells. There are some people who insist that LiFePO4 cells can not sustain a slow trickle charge rate ... but I see a problem with...

A study I found a bit ago that kind of goes into some of the technical side of the gas formation itself. Link

An alternative ... PVDF like Kynar is Piezoelectric ... Kynar Thin Films are fairly easy to source down to 0.001" thick
