Caught this in a commercial watching one of Will‘ videos. He seems to attract quality commercials. very interesting. 750 mile range EV.

Is the below linked switch sufficient for an inverter bypass? Currently, shore power goes to the inverter and then to the panel. If the inverter is offline, shore power cannot pass through. I want to be able to use shore power, independent of the inverter, when I need to. VictorsHome...

in much the same way you can drain a single cell, you can also charge a single cell. Are there any finer details I should be aware of before I attempt to do this? Any advice or suggestions? I have 2 lower SOC cells. easier to charge them than drain the 6 others.

I bought some 1ohm 25 watt resistors (shown in the picture) to be able to individually drain high cells across a battery. Essentially a manual balancer. I soldered some copper wire to the ends and put some heat shrink over it. Works well. drains ~3a (as expected) while its connected. If i leave...

This is the last of 5 I bought directly from JBD. I decided to go with a 24v (8s) system, instead. I was holding onto this last one for the heck of it, but thought I'd throw it out here and see if there were any takers. $100 for the BMS, includes flat rate USPS shipping to lower 48, bluetooth...

These are hardware BMS, no frills (no bluetooth, not configurable: the HVD is 3.9v and the LVD is 2.2v). I paid $470, asking $300 + shipping anywhere in lower 48. Happy to use whichever carrier you choose. I bought them direct from JBD, in a pinch, overlooking the voltage settings. I...

@Will Prowse Will you review https://diysolarforum.com/threads/shenzhen-luyuan-did-i-get-what-i-paid-for.27544/ One of your mods is making some very questionable decisions, which in light of, raises concern or suspicion that they may be trying to conceal alleged misdoings of a specific...

I am considering lining the bottom of my battery box with ceramic fiber insulation. I will also cover that with neoprene rubber, which my battery packs will then sit on. Is ceramic fiber OK for this purpose? Will it have any type of reaction with the electrolyte in LFP should anything leak?

Can anyone suggest a good teaching resource for drawing circuit and wiring diagrams? What information gets included and where? I've been following my own little diagrams that mostly (i assume) conform to regular circuit diagrams, but I'd like to properly learn this and in turn draw up proper...

Anyone know the specs of the thermistors used with the chargery BMS'? Or know how to pinpoint them?

I have a ground fault device i plan on installing between my solar system and my battery bank. The installation instruction diagram is in the below pic: My DC negative bus bar (which is depicted as "terminal bus bar" in the diagram) is bonded to ground. if I were to install the gfdi breaker...

Hi all, I have a 2p 24v setup that I am implementing. each 24v battery has a BMS as well as a 200a fused connection to the disconnect which then feeds the bus bars. I am toying with the idea of permanently placing a resistor between the fused ends of the batteries for balancing purposes (as...

@Steve_S which side of the circuit are your chargery shunts installed on? positive or negative?

Going through the final checks of my electrical system. Ive attached some diagrams. i should note, by design, the chassis system has some circuits that use chassis as a return path. No house systems do this. Inverter is a samlex evo 4024. Feel free to ask for any missing information. I will...

There are some details left out. I didnt include a full schematic of solar, for instance, but it is a 3s2p system. 2x 40a mppt controllers. panel frames grounded to chassis. house battery consists of 2x diy 24v LiFe batteries with jbd 250a BMSs fused separately at 200a each. Inverter is a...

Do I have to run a cable all the way to motohome chassis ground from inverter chassis, or can i simply tie the inverter chassis ground to the battery negative inverter terminal? the battery negative bus bar is connected to chassis ground, already. what are the ramifications of sharing the...

I need to join my 2 battery negatives (1/0 each) into a single 4/0 butt splice to 4/0 wire. i am joining these to run them through the shunt. I could just put a 1/0 lug on the end of each battery begative, then double the 2 lugs on the shunt stud, but my concern is this may cause resistance...

Excited to announce I made the purchase of most if my electrical system components. Less than $1700 on (this is whats in the picture): 1x Evo 4024 inverter/charger 1x Evo 4024 remote 1x class t 350a fuse kit 2x class t 200a fuse kits 2x spare 200a fuses (ordered 2x spare 350a as well, but are...

$250 shipped in continental US PM me for details if interested.

Anyone have knowledge of these BMS? it’s the same mfg of the overkill solar bms’. these claim 200a continuous. Is that wishful thinking?

Hi All, Unfortunately, the BMSs i ordered from alibaba are sitting in a port somewhere and I’m not sure they’ll ever get to me before I submit for a refund. So...i am wondering if the following plan is safe enough to proceed. Any input is appreciated. without a BMS: I will connect 4 cells in...

I am planning 2x 24v battery banks and am considering a chargery BMS8T to manage each bank. They come with their own shunts and I will be using DCC contactors in common port config (still considering separate port config). My dilemma is this: each BMS has its own shunt and thereby monitors the...

I’m not thrilled about the inverters they carry, but wondering if that 60A mppt controller might be worth biting on. https://lephenixenergy.com/product/le-phenix-energy-solar-charge-controller-12-24-48-60a-mppt/

Hi all, TLDR; Managing parallel connected batteries as a single bank with a single BMS connection or BMS connection to each individual cell? Given 16x 3.2v 272AH lifepo4 cells, should I start with a 24v system or 12v and upgrade later when I purchase more cells? And here are the details of...

Hello all, I am new to this forum; however, after scouring several of @Will Prowse videos and reviewing the information held on this site, I just purchased 16 pieces, Lishen 3.2v 272AH battery packs from dongguan lightning new energy technology on alibaba. My total price was just under $1700...
