    Please help me to learn solar inverters, and what I should look for.

    CS, How will you use your solar? Are you allowed to sell back excess power back to the grid? How much space do you have for solar panels? To give you an idea: In MI where I live the quote to sell back excess power has run out. So if I put in solar, either I have to use ALL of it or store the...

    Molicel P42A, Sony/Murata US18650VTC5D in 14s5p battery packs sounds like a good deal?

    I had to pause on the batt, I was tied up with coaching middle school tennis and few volunteer days running sailing races. Taking a break tomorrow to fish some small mouth bass. If any of you have your bms middle section some what intact, can you double check the 5 small pins in the middle and...

    How long did you short the 2 short blade pins for? I remember reading the TI whitepaper and it mentioned a delay. connect the 2 short blades and leave them connected and then press the batt level indicator switch, does it show a level? Also, before you start charge your batt to 53v first...

    Floyd, I was procrastinating while you took a stab at it :D I really have on use for the batt/cells now, just bought it cuz it was cool, I want to be able to use it as is if possible. Yes, we should be able to reverse engineer the bms. My electronics chi is very low due to a decade of...

    Molicel P42A, Sony/Murata US18650VTC5D in 14s5p battery packs sounds like a good deal?

    I received my order today, these packs are very very very long and bulky, as is, they are NOT usable. My sarcos pack came in with what appears to be a dead BMS (hibernating?), when I press the switch, I do not get any light. Checking each bank I found them to be at 3.55 to 3.53 v I have not...

    500w DD ebay motor with bamboo pegs, what glue?

    I am planning on spraying varnish on the motor, I am guessing you did not have any bamboo pegs walk and get broken off ? Spraying Varnish: 1. Wipe surfaces with 90% alcohol couple of times and let it dry 2. Spray 2 coats? and dry in between Do I need to oven cure?

    500w DD ebay motor with bamboo pegs, what glue?

    I watched Justin take off the side plates with the gear puller and I was sold, bought a cheap 8 inch for $18. Yeah, could not believe how simple it was to take off the side plate. I was and am still little scared to put my wussy, girly fingers in between the stator and the magnets. I can't...

    500w DD ebay motor with bamboo pegs, what glue?

    Early summer last year, I hurt the outside of my wrist, putting weight on it brings the pain back. I wanted to build a simple, light, inexpensive rear DD motor full suspension bike using a free frame I was given by a guy on FB. I found a 500w DD motor on ebay for $103 and it looked good on...

    Amazon 48v battery inspection

    Return it, that cell with the burnt wrapper is probably damaged by the heat, wow the proper solution would have been to spot weld a tin strip to the cell and then solder the wire to it. Kudos to you for opening it up.

    Charging a Li battery from a 4Runner alternator.

    Yes, sorry, I would charge the bluetti off the alternator and use the bluetti and an A/C charger to charge the battery. Better and cheaper solutions for charging via AC than DC at higher voltages.

    Charging a Li battery from a 4Runner alternator.

    OP, 1. you can use a booster converter charger like this one: https://ebikes.ca/shop/electric-bicycle-parts/solar/adjustable-400w-boost-mppt.html this take 12v to 24v input and boosts the output volts per selection. 2. One word "Bluetti" ya man, #1 is cheaper and I not a fan of the magic...

    Suitable battery for an 1800W 48V 38A motor?

    FYI: My experience with Jag35 has been very poor, they sent me DEAD used cells which in my books is dangerous. I would avoid jag, Batteryhookup and batteryclearinghouse are 2 have bought from and they have worked with me positively to resolve issues, plus their prices are much lower than jag35.
