Had a rare power outage in Vegas. My solar is grid tie only so I got this wired up to run the office until the power came back up.

Just want to share my thoughts on Emily from Basen. Super quick turn around on questions and shipping was FAST! UPS showed up today and I was confused when he said 8 heavy boxes. I walked out to the truck to see the basen logo and was giddy. For everyone in the US looking for quick turn around...

I wouldn't call it unnecessary. Most BMS' only do small current because they are doing it internally. My BMS has external balance/monitor boards so you can fit larger resistors. Even so, 1 amp isn't that much if you are charging at 120amps. The SBMS isn't a charger, just a BMS. The DSSR20...

I'm on cell 6 of my testing and they are all around the 310-311ah mark. All are testing good!

30mA * 24hr = 720mAh per day. a 100ah battery will be drained in around 139 days just from the BMS. It happens all the time in the boating/RVing world that store their rigs inside. This BMS does have a sleep function. I'm curious if coming back from sleep also resets the settings. I'm going to...

Okay, I've been playing all morning and I figured out the issue, and this may have been what was causing the issue with the resetting of the settings in the first place (The bug is caused by a logical error in the parameter entered by the user.). Cell over voltage protection recovery has to be...

I got my busbars from eel and they actually have a nut embedded for voltage sense/balance wires! Very cool!!

I will be using a Rec-Active 12v BMS on my 1240ah 12v system. It has a 2 amp active balancer built in. However I figure with a bank that size I'd like to have another battery balancer to go with it just in case. I did some research on inductive balancers as that's what REC uses and opted to go...

Just checking in. Finished capacity testing each cell individually. All cells were discharged to 2.8v then charged back up to 3.65v and let absorb until 20amps was going in. The lowest cell was 309ah and the highest was 311ah. Needless to say I’m impressed. I will only be charging until 3.5v...

I'm using a REC BMS, so I'm not going to split and have multiple units. The double bus bars will only be for the serial connection.

Interesting, I'm curious what the difference is between hardware versions.

This issue has been figured out. See my finding in the larger JK thread: https://diysolarforum.com/threads/anybody-tried-new-jk-bms-with-inverter-communication-support.68964/page-9#post-973085

Well I feel really stupid. I’ve been around for about 7 years, installed Dozens of system and finally accidentally swapped two balance cables during a bench power up to update some firmware. Rec has user replaceable fuses but I swapped cell 1 negative with cell 4 positive so I’m hopeful that...

A proper setup! Nice job!!

DZL hit most points dead on so I really don't have anything to add regarding SBMS vs Chargery. Another BMS that does active Balancing is REC BMS but ONLY on their ActiveBMS and that's only on 12V. I've asked them about a 24v model as there larger units still only do passive balancing. I will...

I've done just that. Here is Cell 4 at my first test, then at your suggestion of 2.5v discharge and recharge to 3.65 with absorption until 400mA. Not much to be had by doing this as I went from 5.039ah to 5.382ah for a 6.3% increase. Cell 4 with 2.5v discharge and 400ma absorption: These...

Kisae DMT-1250 if you are using a 12v battery. It has a PV input range of 14.5-50v. I also like it MUCH better than the Renogy because it does one or the other. So when you are driving it does up to 50 amps (programmable in 5amp steps) and ignores solar. When you are parked it can support up to...

You might to reconsider your pricing. You can get a brand new 8.16kw system installed from Tesla for 11k after tax credits.

FYI Helen from JK emailed me (I didn't email them, they must have reached out to buyers of the new bms) and she included the 14.19 firmware with release notes: -V14.17 Upgrade logs 1.Fixed a bug where parameters were lost after BMS restart. The bug is caused by a logical error in the...

It looks like a lot of sellers are now going to be replacing their EVE listings with Lishen. I've asked Emily from Shenzhen Basen Technology for spec sheets on them so they can compare to EVE. I'm mainly curious about the mounting threads. I've seen some other aluminum cased cells with odd...

Success!! Fuses replaced and BMS is fine and reporting no errors! Thankfully this was a cheap mistake. $8 for 10 fuses so if I do it again ;)

First cell test complete. I only discharged it down to 2.8v instead of 2.5v then charged it back up. Ignore the fact that it only discharged 44.43ah. My computer crashed during the first cycle and it was already at the recharge phase when I started the test over (discharged again). I yielded...

oops, I'll see myself out.

Yikes. I was considering these but at those prices and needing 4 it’s just too much. Cool idea but those prices are kind of hard to swallow. I understand it’s small batch runs on a 3d printer so it’s not worth your time to sell them cheaper. Maybe get in touch with a plastics company to see if...

These are expensive for what they do, but it's an easy hands off box that's worth the money for me as it just works (sorta). I used one on my old Powerhouse Auto BMS that used a 500amp contactor. As @MurphyGuy stated, mine also was adjustable from 2-11 seconds but it never worked higher than 4-6...

Thanks for putting this together.

Yes. The Multiplus is an expensive inverter/charger. A $2 board to protect your $1200 inverter/charger is worth it.

Send a unit to Off Grid Garage and have him make a video. It’ll be fixed in a few days lol

well for me, i originally bought them YEARS ago for a dump when I was capacity testing my cells with a powerlab unit. Since then I just use them when I need a 12v source for testing. I've run them down to 0v way too many times and my old set finally died. I already had busbars and cell holders...
