HI Gang, Here's an odd one ...... all day my system was not charging ....... That was reported by the panel if my KIASE Charger /Inverter BIC1220080 saying it was at 74% and dropping and this was at 3:00 in the afternoon. I only have one 330 Watt Can Solar panel but it was producing, and...

Hi Folks, I just got some new cells from a buddy and they now in a pack of 4 and ready to go. My question is on what to set the parameters for on the EPEVER Tracer 425 BN I can't find the "specs" on the batteries /cells? They are the standard 3.2V LiFePo4 cells from China and the capacity is...

Hi, I have a set of four standard LiFePO4 cells from Basen in China I used them on a road trip to power a fridge however since I got back they seem to be acting weird. (I know, very highly technical, right?) Yes, total newbie here .... hence, I'm in the right forum topic anyway ....... The...

Because when you're not working it's nice to stay busy and have fun budget or not. As for a JK I looked at a link from Andy's site and also went to the JKBMS site directly ( https://www.jkbms.com/ ) and don't see a model listed for a 4S battery pack .... can you point me in the right direction...

Hi, Thanks for the reply .....so the Overkill brand of BMS's don't have any balancing capacity at all ? Cheers' Dave

Yea,their site is much clearer to order off of then Jk's it seems (to me anyway) - I was thinking of the 4S with the 24" leads ...... This one: 4s BMS 120a LifePo4 with 24″ 8ga Wires and then get the Bluetooth module .... what do you think?

Hi Eggo, I'm trying to make sence of your post: "you have a reputation for insulting people." | It's not Ohm's suggestion, it's Ohm's Law. | My advice is worth what you paid for it... maybe less | Unless otherwise specified, my advice is what I would do and may not comply with code | All...

Does anyone have an opinion on the JK-B2A8S20P BMS's ...... have you used one? Are you happy with it?

Hi, Could someone please tell me the correct size of copper cable to use on this 50-8 crimp terminal? If you could point me to a cable/ lug size guide that would be great too ..... Cheers' Dave

Oh no, I saw and expanded that and saw the info you typed in - thanks for that ! But that is a very odd sig file ! (grin) Cheers' Dave

Hi, I'm hooking back up a battery pack to a KISAE 2000W Inverter/Charger and I have a question about "tweaking" the charging settings. The batteries are four (4) standard LiFePO4 cells from Basen in China. They are: 3.2 V LiFePo4 Cell Capacity: 272 Ah Voltage: 3.24 V IR: 0.12 m Ohm So there's...

Hi Gang, I finally got a new JK-B2A8S-20P BMS, now the fun part. My old (now dead) DALY that i got with the it had no user definable settings. This New JK BMS is asking for lots of variables now - holy crap ! I'm going to start reading the doc in the beginners section called: " Voltage...

Hi HRTKD, Yep, that's true, but the control panel for the inverter was also saying the same thing - the batteries were down and not showing anything going in but once I did that solar controller and the 330 W panel - disconnect and reconnect after about two mins. Then That panel also showed...

Thanks for the info ...... !! I'll go plug in the values. Cheers' Dave

Hi, I've got a new system here that I'm setting up it's only 1 Can Solar 340 watt panel going to an EPEVER Tracer 4215 BN and that's the unit I need some help with the settings for a LiFePo4 set of batteries. I'm not exactly sure what the best number would be for these parameters ...

So you're saying battery pack to a BMS and then from the BMS to the KISAE ...... OK if that's the case I will (once I get anew BMS) but then that still doesn't eliminate what would be the prefered settings if I did want to try the KISAE's charging option. Ideally someone can suggest a set of...

Oh there is just the one EPEver controller, the path is from the 330 w can solar panel in to the EPEver and then out of that battery side of the controller to the buss bars. The Positive line from the EPEver controller goes thru a breaker that's connected to the buss bar, the buss bar also has...

AH OK, I'll get a BMS and go back to normal - Panel to ChargeCon to BMS to Battery ...... Tks !

AH ! Good point ! Thanks !!

Greetings Folks, I'm at a quandary I need to get a new BMS but I'm stuck ...... and it really boils down to who's? OVERKILL / KJ / DALY If I go to Overkills site - its a normal experience - look! Products clearly labeled with what it is, and what its for, and what it cost. Who knew...

Hi ! Thanks for the info ...... I'll go change that right now! BTW Is there anything else that needs adjusting and can you suggest any readings for the other settings? I'm not seeing a ton of good info on the web as far general info. Cheers' Dave

Hi, I have a very simple setup to "play" with it's a ........ My one panel is a Canadian Solar CS3U-380MS Nominal Max Power (Pmax) 380 W Opt Operating Voltage (Vmp) 40.0 V Opt Operating Current (Imp) 9.50 A Open Circuit Voltage (Voc) 47.8 V...

Hi Bentley, I got the Start Bal and the Cont Charge Current changed but when I tried to do the OTP and UTP, I get send error ...... Just to make sure - its these, right? Charge OTP (C) __43.0__ ( was 70.0 ) Charge OTPR (C) 60.0 Discharge OTP...

Here's what I got .......

Hi Gang, OK, the new JK is installed and seems happy ..... I do have one weird question tho. I watching videos it seems that 3.45 or 13.8 is a sweet spot and I have the charge controller floating to that ...... Im looking at my sexy new JK panel it says that I'm at 88% and I did put in that...

Hi 40Fan, Cute timing I'm watching Andy right now .......... My only question is really - what's a decent voltage and a mild but happy current I can use with my bench supply to try to top off these cells...... I was told 3.65 and .300 of an amp to slowly see if they'll hold anything ...
