I wonder if they are sturdy enough to stack 4-5 high?Or you can go in between and purchase a 16s kit and put it together yourself. Was considering this one from Luyuan which is a trusted seller. Can get it configured for a JK Inverter BMS.
I was wondering that myself but you would want them on separate shelves to begin with so that if you have to pull the bottom one you don't have to unstack all of them. Was thinking some kind of heavy duty metal shelving system like 4ft wide Dewalt one. People who get multiple PowerPros seem to have issues with spacing since they are designed to just be placed vertically on the floor more or less.I wonder if they are sturdy enough to stack 4-5 high?
why you dont want to mess with 100Ah small capacity?DIY or Powerpro is my preference. I don't want to mess with 100Ah's anymore although I don't mind having my one of them as an auxillary battery.
Just because to me each battery is something I'm going to give a bit of individual attention, check its interface and cell voltages, etc. and so for a big battery I can get 3x the capacity for the same amount of baby sitting.why you dont want to mess with 100Ah small capacity?
To me, at some point the compactness, simplicity, and flexibility of a pre-built 51.2v/100AH rack unit simply outweighs the cost differential. Everyone keeps telling me that they keep putting all these DIY systems together for next to nothing,
I don't have a problem lifting each cell one at a time into the bank.......but everytime I start adding up the stuff I want, the price difference drops dramatically. Not to mention the weight aspect of a 15KWH/300AH set of prismatics.
DIY every time for me, even if it cost $1000 more per 15kWh. I like the control of my DIY BMS to Inverter software and knowledge of how it all works.If you were to buy batteries today for your system, which would you buy and why?
Disagree. My DIY batteries come with a 5 minute SLA response time, 24/7, 365 days per year. If something ain't working, I would want to resolve it now, even if it's me in my pyjamasMore expensive, but in theory, if warranty is needed, someone else is holding the bag.
Quite happy with my hand-varnished plywood box!the rack batteries would look good.

It will be compact, like this.

After eight years with ihree iterations of DIY batteries and three different inverters I finally went with Pytes rack batteries. A lot of my motivation was the fact that I had been running those systems without a building permit and I finally wanted to have a UL listed system so I could pull a permit. The cost was close to $400 per kWh including the UL listed enclosure, compared to the DIY batteries which cost less than $100 per kWh.If you were to buy batteries today for your system, which would you buy and why?
It's good to have the option to get a permit if needed someday. I see alot of people say they will never get a permit, but unfortunately sometimes the AHJ forces you to get a permit or tear out your systemAfter eight years with ihree iterations of DIY batteries and three different inverters I finally went with Pytes rack batteries.

Next build is as follows.Zwy has a great custom rack.
7000 60KW of 300AH batteries
0500 4x 100A BMC
0030 standoffs and mounts for the BMC's
0400 6x4ft Threaded rod + Bolts washers etc
0015 2x8ft 1/2" PVC pipe
???? Interesting cabinet
???? 300A BUS WIRE/Infrastructure . . 4/0? $8/ft paired 2/0 or 1/0?
Realistically closer to $9-10K, with the cabinet but still a big savings. Kind of, tough to move around. Weak aesthetics not that that really matters.
Linseed oil, I believe, provides a more natural look than varnish, and is less toxic. But yes I believe your premise is correct!Quite happy with my hand-varnished plywood box!
Sounds very good price, but I would have thought that opening up the packs and installing a 3rd party balancer on them would void any manufacturer warranty?With this price I seem to get working warranty, but rack has no busbars on it and BMSs are equipped with ~50mA passive balancers. I think I paid 60e for two big copper busbars and made bushings out of POM for it with my lathe. Then need to open up every batt and install Neey balancer wiring harness on them (11e). Only one actual Neey 4A smart balancer (80e) is needed as it is only needed for few days max on each battery per year.
Might be true, but my vendor friend handled my one warranty matter so far and they didn't ask any specifics or pictures. I think my friend buys enough from them so little things like replacement cells + postage don't matter. They did offer free change of those cells too, but I wanted to see how these batts are constructed and did it myself. Now I'm sure I could DIY 16S battery if needed, but with these prices I see no point in that. Actually I did order 2 x 10kWh more of these batteries week or two ago.Sounds very good price, but I would have thought that opening up the packs and installing a 3rd party balancer on them would void any manufacturer warranty?![]()
