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 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...
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...
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...
Up for sale is a brand new, never opened (still sealed) Victron GX Touch 50. This is just the screen for the Cerbo GX. I will be upgrading to the GX Touch 70 so looking to let this go. These sell for $221 plus tax. I'm looking to sell mine for $210 shipped or local pick up in Las Vegas.
My 304ah cells arrived the other day. The only option were the welded stud option so that's what I went with. Since this is going to be installed in to a camper van, I opted to buy an extra set of flexible bus bars that I saw on @LithiumSolar youtube channel () to better handle the road...
I've got 8 105ah cells for an 8s 24V pack that I want to install for a portable rig. I've got a box that is compact but I think it might involve installing the cells on their side for the best position. I'm pretty sure this is NOT a recommended method. Any feedback?
I've got a few questions regarding the best way to make a series connection when you've got individual cells grouped in parallel. For my last battery it was laid out like this:
There was only a single busbar making the series connection to the next group in a staggered fashion. This worked...
I'll be installing a 8sp2 system into an EEL server rack battery box for a 24 system with the new JK BMS inverter BMS. EEL sells heating pads (designed for 48v systems) that has two pads in series. I figured the lower voltage should just halve the power. I measured the resistance and it's around...
SOLD!
I have opted to go with 24v for my van build and deciding to sell my rec BMS. It includes includes:
Rec-BMS 12v Active
Rec Active wiring harness
Rec Precharge unit
Rec WiFi module
Rec Victron can cable
Used tyco 500amp contactor
Used 500amp shunt
Can include a Victron battery protect...
I’m switching to 24v so selling this dcdc charger. This has reverse charging so it can help jump or charge your starting battery. Will include the option remote. These are pricey units and I bought from uk and paid heavily with import fees. My loss your gain. $900 shipped for both. That...
This is great explanation on how active balancers work. If you don’t already know Stuart he is the one man band behind the diybms. This guy does fantastic work.
This video explains why active balancers current decreases as voltage is closer. The wider the deviation the higher the current:
I purchased 25 panels but only installed 24. These are B grade panels but are still rated for 400w. Model isJKM400M-72HL believe but will have to double check. I've been using the panels on my home in Las Vegas for almost a year and they are solid performing panels. There is blemish on the glass...
Up for sale is a brand new Victron BMV712. I purchased this for my new van, but ended up going with a REC-BMS which has it's own shunt to act as the battery monitor. Totally unused. Asking 190 shipped or local pick up in Las Vegas.
Up for sale is an Electrodacus SBMS0 bundle to get started. I only want to sell as a package. It includes (Listed with price I paid):
Electrodacus SBMS0 (old version with side connectors, but has USB and wifi and extra plug for EXTio 5 and 6 connected) - $150?? I don't remember
Electrodacus...
I'm in the process of ordering some new 304ah cells and found that they have a new spacing compared to the old cells:
OLD (taken from a google image search):
And the new:
The reason I ask is I plan on ordering replacement flexible bus bars...
I plug in my electricity cost from the grid into my monitoring software so it can calculate cost/savings (more importantly for me will be when I break even and that's looking to be under 4 years for a 9.6kw system). CTs calculate load on the host as well. It's been 2 years with solar and it's...
Just a heads up these are advertised at 95% capacity and after testing 2 of the these cells, I'm seeing closer to 67% capacity. Now I'm only discharging to 2.8v, but I think going to 2.0v with lifepo4 is too low and probably wouldn't yield that much more. My test:
Charge to 3.65v at 4 amps and...
Up for sale is an EPEver IP2000 24v inverter. This unit says 2000w on the cover, but it's actually a 1600w. I've modified the on off switch and added a female phoenix terminal with removable male jumper. This was to be used with the electrodacus SBMS0. However if you don't want to use the SBMS...
Up for sale is 8 EVE 105ah cells. They have two cycles on them for testing the Electrodacus SBMS0 (also for sale). Looking for $425 obo SOLD!! Pick up in Las Vegas only or pay actual shipping cost (will vary based on location).
Up for sale is a new 150/60 taken out of the box, firmware upgraded and tested, then put back in while I wait for my van. This unit is oversized for my setup, but that was because I was going to use an Electrodacus SBMS and use the remote on/off port. However now that I switched BMS' to a REC...
What is everyone using to calculate their bus bar current rating? I've always heard that 1.6 X mm2 of the bus bar, but I've been reading that that might be too generous. Some say 1.5 others say only 1.2. Curious what everyone does. For example 1/4in x 3/4in thick which is 6.35mmx19.05mm =...
I've got a DIY Lifepo4 battery bank that I'm going to be installing in a somewhat unique fashion. I have 16 304AH 3.2v cells that I'm going to put into a 12v bank with 4 cells in parallel then series those groups for a 12v bank. However the unique part is I'm going to install the 4 cells in...
I just picked up a full EV (traded in my phev and got a great deal on a Chevy Bolt EUV). I already have a level 2 evse but I've had my eye on the solaredge unit because the data will be in the same mySolaredge app plus it has Charge Via excess solar only options. My PHEV had a max of 4kw I think...
I've got 24 304ah cells incoming and need to test the capacity so I'm sure the cells are what they say they are. Does anyone in the Las Vegas area have one I could borrow? If not, looking to buy one not shipped from China as my cells are coming from the US.
Thanks!
I'm considering buying 32 EVE 280ah cells for battery storage for my solar install in Las Vegas. NV Energy will provide up to $3000 if I switch to TOU and $1500 if I stay on a normal rate. I'm consider switching to TOU and sell back to the grid from the battery at the higher rate and recharge...
