On the opposite to regular Lithium cells like NMC, NCA, LiPO, LiCO etc, the LiFePo4 cells never realy improoved in energy density. They keep theyr life cycle incredible and flat discahrge curve. Personally io made many packs with LiFePo4 and mostly A123 pouch and round cells and i always prefered th...

Hello guys In the past years i recived ton of request for supporting people with their SEVCON adventure if i can call it this way :confused: Going with Sevcon is a complicated adventure for most of people. Only a small portion have the real experience to play with that and understand WITHOUT the nee...

welcome back, you've been missed!

Thanks John, I am really busy now but make effort to keep active my presence here.

Thanks for the effort NCC1941!!

That is encouraging. I will try to find how to stop the scrip that block the thing.

I think there is a problem with the GPS file upload with the web app. It work with the CA file no prob, however once i try to add a GPS file and clic on SUBMIT, it keep waiting infinitly. I tried the files from Justin exemple and it also wont work even with these. Anyoe else is experiencing that pro...

I noticed doctorbass has been largely absent as well, though that could just be a coincidence. I've read through many of the old posts here at ES and it seems that at least a few of the people who seemed to be on the bleeding edge circa 2015 or so are either notably absent or no longer contributing...

I am actively searching for a inverter that is: -1 or 2 MPPT input ( idealy starting from 60VDC and not 200vdc as i have some string of 2x 60 cells panel only) -Grid Tie -Hybrid (battery backup input) -48Vdc ( not 24, not 12) -Certified UL or CSA. - 4kW and more It seem a real pain to find some that...

Thanks cricketo, I did not know that there are battery-powered off-grid inverters that generate the sine wave necessary for grid-tied inverters. And that SMA does that. I saw great bargain of some large SMA inverter at very nice price however these are not split phase so you need two that i guess ar...

Thanks you Bill. I made a video to better explain the experiment. Btw these Enphase are isolated from in to output except for the AC ground that have some high capacitance relative to the DC side. I saw these chineese inverter /charge controller that control the output to contyrol what they dump to ...

Hello guys, In my solar project i am making some testing prior to see if some concept are working. You can get very cheap used old micro inverter like the Enphase M190 and to increase their power you can paralle them if you use these outside their MTTP voltage range when powered by battery. In these...

Hello Jones, I'm back here on E-S since few month. I have less time for the forums so i sometime take a brake. Yes it is possible to supply the input with battery instead of PV power. I actually have a Solar project that will use a bank of 8 Enphase M190 micro inverters (that i got for 80cad$) all c...

On my side.. Yes they work in parallel... well at least the M190 that we today can find for about 10$ each used and still 100% working! I tried 2 in parallel from a batch that i bought from Ontario,Canada.. and YES it work !!! I got some 300W 60 cell panel and i tought it was a big sacrifice to let ...

The cheapest way to convert 48Vdc to kW of sine AC is to get used UPS !!! I got a APC 5000VA ( 4300Watts) for 200$ no battery inside. It work really well for the cost!!! similar to this one.. but it output 208Vthat i converted to splitphase 120-120AC https://www.kijiji.ca/v-electricite/laval-rive-no...

Remmie, Any instructions for the Flatpack 2 HE 2000W 110-125Vdc model like on electricmotorcycleforum ? I tried couple serial number and voltage commands like published here for the 48v models here but i can't get it to change voltage output. I want 116.5Vdc output on one unit of model 125Vdc 2000W ...

Hmm I see power here!!!

Properly installed/used copper buss, excellent current share, great thermal management, well protected cells, AWSOME WORK

Doc

These BAC controller are very nice. Plus these are from ASI, a Canadian company 8) It would be VERY interesting to get every possible adjustment on the screen and get rid of the computer for programming... The Adaptto platform allow that and even can communicate with the BMS.. ...Well all settings a...

Please guys READ ! I receive many emails asking for shipping quote!!

I wrote Local pickup ONLY!

Thanks for understanding.

Hi all, I have couple Original Ebike battery pack. Like NEW manufactured in January 2018. -48.1V nom 13Ah ( 624Wh) -These come with BMS -1C continuous 2C burst ( fuse 30A) -In and out are the same wire -Made of Original Samsung ICR-18650-26F ( 2600mAh) 9.6Wh -These come with 16 gauge Silicon wire. -...

I have found that, a published very surprisingly simple way to do that!

Merlin, Was this frame from a batch that was sold with deffect and agreement? (the only agreement that NYX actually accepted but never should have been)? I heard that they sold a small batch to someone in Europe that accepted the fact that they are deffect and paid less for but after he received the...

I pre heat my Volt during winter season. That's pretty common of all Volt owners that live in area where winter is cold.

This not just heat the cabin but also the battery witch improove his energy output

Hello i'm looking for a 240v variac that can take 15A+

Please PM me if you have one for sale!

Thanks

Folks, Does anyone on this thread use QS205 V3? And if so, what are the setting parameters that you use on your Adaptto? I'm actually just starting on my build, and I keep hearing that some folks get their motor very hot with the Adaptto... In fact, wouldn't it be a good idea if folks can share the...
