Добрый день, спасибо за очередной обзор замечательной продукции. Это просто супер до чего всё обработано и продуманно. Это отличное решение для электроснабжения загородного дома или коттеджа. Существенная экономия электроэнергии для промышленного предприятия. Я рад что есть такие производства и продукция, которые созданы для людей, для облегчения их жизни и обретения независимости от электроснабжения государства.

[@Aleksandr03071970]

Good afternoon, thank you for another great product review. It's just super-processed and thoughtful. This is an excellent solution for supplying electricity to a country house or cottage. Significant energy savings for an industrial enterprise. I am glad that there are such industries and products that are created for people, to make their life easier and gain independence from the state power supply.

[@Boazizione]

I really like their batteries and the quality, their BMS is very Good. What i like about their batteries is that the cells are Grade A cells, and the pack is compatible with most of the top brand inverters like SMA, Victron, Goodwe, Deye, Voltronic, Growatt etc, I recommend for anyone that wants to use lithium batteries because their prices are very competitive and products are quality

[@SeplosTechnology]

Osei bright Thanks for recommending.

[@trompbakker9545]

The Seplos logo looks like the Tesla logo. I'm new into batteries and energy storage. It's becoming a hobby.

[@geraldmuchenje8780]

I like how they a stackable. And the quality of the build. It would be interesting to have data logging for service inspection warranty and even IOT and get performance data from the field that u can use to improve designs and advise customers on battery health before anything catastrophic happens

[@Justaguy0420]

I’m sure they have data logging in their software. Most BMSs do. It uses RS485 so by nature it’s absolutely possible to integrate into your BAS. Cambus modbus bacnet lonworks are all capable of IOT integration. Probably won’t see it on some customer grade software like google home or apple HomeKit but it’s probably already being done.

Great video. I saw quick connectors in this video. We manufacture plug-in connectors.

[@marksermo9110]

Thank you very for this interesting movie! Very nice, and well executed system! I do have just 1 well-intentioned comment: Parts that are connected to each other with (screw) connections, through which Voltage or Amperage runs, may possibly cause "amperage corrosion". Think of the white deposit on the plus terminal of an old car battery. If you apply special battery terminal grease between the screw connectors, amperage corrosion can NEVER occur. Amperage corrosion can even, in the long run, lead to short circuits and/or other defects.

[@adrianfisher4992]

Nice battery pack... It will be nice to have no-oxidation paste on connection between two different materials... And it will be good to install at least 2 temperature sensor on each battery module (4 in each battery pack) to be connected to BMS, not to measure only temperature in box... Also will be good to have some fan to circulate that air when temperature rises... It will be nice to make some tests on this battery pack to give more information.

[@SeplosTechnology]

@JViz Thanks for your correction. You're right. It is in series.

[@oneandahalflegsawm]

very clean expandable design

[@ReflectedMiles]

Nope, we start out by measuring the voltage of each cell to see how well matched they are or if there are any bad ones, and THEN we start slapping on the buss bars and finish the balancing if they were already close. If they weren't, we send the mismatched ones back until we have a quality set to start.

[@SeplosTechnology]

@reflected Miles Thanks for your professional advice. In this video, we're expecting to present a way of cell balancing for DIYers, whose cells are with a slight capacity difference. Actually, the cells in the video are Grade A cells pre-matched and grouped with a capacity difference of only ±2mv.

[@ReflectedMiles]

@@SeplosTechnology In that case, my amended procedure should verify your excellent work instead of verifying after they have already been equalized. Think of it as the Will Prowse Standard. Professional, indeed!

[@shirkedance]

Awesome DIY setup. Neat and clean. I would prefer to leave 1 or 2 inch gaps between two batteries. Just for safety concerns, in case one battery leaks or swells it won't damage the other batteries . Chain reaction

[@NiceFabe]

you need to press those kind of lifepo batteries to prevet them from swelling otherwise if they got "space" they for sure will use it and be more damaged because the layers inside the cells will move and even break

The only issue is the limited output capacity due to the power running through each subsequent pack's cables and internal bus bars. A better solution would be to have each battery in parallel through a very large external bus bar so that the total output is that of each pack added together, and not just one pack. Great setup though for a large capacity low draw system!

[@reginaldpotts2037]

At least you did a diagonal connection to the inverter but... If each of these 6 packs is capable of outputting 100A of current then technically the cable nearest the inverter connection could carry 600A in the event of a problem. I can't see the rating of the short daisy chain cables but they look flimsy and certainly not capable of that amperage. I would not be happy to have this setup in my renewable energy building looks like an accident waiting to happen.
