@Fish Freak Hi, Guys, just released, in factory mode. suppose i still make it as i promised it will be ready at mid of June. anyone interested in, pls drop me the message, and more details will share with you :). Cheers

@JoeHam Just push them to contact with you :) My bad, as i was a bit overwhelmed recently and take it for granted that my team will contact you after i give them the info. Cheers

i put my partial spec here for reference, the final one would be slightly different. i am coming up with the final product. Really busy recently :) Cheers

@Gazoo ya, Bluetooth could be an add-on option, i will add it in, probably, in ver. 2.0 :) hooked in series is fine, the tricky part is in parallel mode due to non-balancing issue which should be controlled by BMS. the BMS used in this forum mostly is should be called as protecting board, it...

@Fish Freak the Bluetooth problem is the power consumption itself, too large :)

Yes, I will make the complete solution, preorder may come very quickly, will you be interested in :)? The best in class battery with the reliable BMS, And an affordable price. no kidding :)

@Fish Freak and all, it took me some time to do home work on the BMS of 12V/24V and what has been used in the current most recommended battery. And i finally know where i should go. for those BMS you suggest and used mostly in this forum, are from China in fact. and the pros and cons are coming...

So now the battery does not server you well, i suppose :) never mind, a very competitive solution will be there.

@Fish Freak really enlighten me, will find way out to do a stud welding and the case to constrain the cell individually.

you know, he has been there more than 8 years. and really contribute much to SAE standards by also taking CATL up to the equivalent level, veteran in EV automobile area.

i am just curious about how long (years) would this kind of inverter can last in continuous use practically. since they are originated from UPS inverter, can yield quite large power but the reliability is not that ideal. can anyone tell me? Since what i tested mostly are the hybrid inverters...

no comments on office politics :) Cheers

If you are looking for 48V system, you may take a glance at Power Lite Series powered by CATL LFP 100 Ah battery. With TUV certificate by complying IEC 62619 and IEC-EMC 61000 standards. May i know what inverter you are using, and see if Power Lite has compatible test with it or not. The...

Chargery locates just byside, i may drop by on site :) Cheers

@Fish Freak @Gazoo @JoeHam @NEWYORKHILLBILLY Hi Bros, what an intensive discussion have been raised. I made some wrap-up in order to move forward correctly. 1. a stud welding on top of positive and negative port: let me check if i can come up with better idea to give more option for DIYer. but...

replied your email,bro. i am a bit busy recently :) sorry for the late reply.

@Gazoo just put my stuff up there, and what BMS are you suggesting? i do not know much about it for small system as mostly using here, since i developed mine own and use it in Large ESS system, which would be costly. your suggestion may enlighten me to find you much better BMS for this...

HI, Guys, just update here, I just use laser welding to do the bundling (6 pcs in series 19.2V as required from one of my customer, showing here as a demo), as you can see, this is 100Ah CATL LFP battery, i leave major positive and negative ports for handy connecting. i also leave a Nickel...

thanks for the suggestion. first i will make some sample and post it here, pls leave me sometime.

You could also offer smaller prebuilt packs with a built in BMS. i think i will first provide something in this way, since my battery requires laser welding. within these days i will go to my factory and discuss with my team. it won't be difficult. i will make 12V100Ah and 12V280Ah first, what...

exactly, but product of this spec. is yet on the market. i know the road map.

@Ryang, will share with you, recently i am on it.

@Gazoo Thanks bro. Ya, i was a bit at sea when seeing so many here would like build their own packs, reflecting the spirit of DIY in one way or the other. But i have to say, be very careful as Li-ion battery is not like a AA, AAA or Lead-acid battery. Lithium is the most active element of metal...

@Fish Freak, that is the reason i post a thread here :), now the bottleneck is not the product itself, and in my review there should not be customer defined in large or small, anyone who interested your products should be taken in a fair way. the only thing bothers me is the logistic issue...

0.5 P you can simply understand it at 0.5 C (140A for this case). For grid-scale ESS the life-span of LFP battery normally is at least 4000 cycles at 100% DoD. for CATL battery, a long-life span LFP battery will run more than 10k cycles and lasting 15 years. That's why the US company named...

Really appreciate your msg. i am double checking with my team on the delivering issue, since most of my products were shipped to Europe. See if i can make it and will let you know. you may contact me directly via wangyx@uzenergy.com or follow us at Linkedin.

200 A, for battery it is quite ok. but i am wondering what kind of protecting board (BMS) have been used to allow 200 A? any idea here what is used by other ones. pls let me know and i need to double check.

thanks for the info. i just do a quick calculation, getting 12 V battery by using LFP cell with capacity of 280Ah, you will get 4*3.2 V*280 Ah=3584 Wh, approx. 3.5 kWh. By taking the spec. from the data sheet, for each cell the weight is 5.34 kg. in this case 4 cells are used in series, and then...

thanks for your reply. in fact, i have the 280Ah CATL LFP battery supply as i use it more than 30 MWh per year. but it is normally used for grid-scale (Wind/PV power plants) energy storage system. and you may find my application case in link...

Why don't you try some premium battery from China, pls check my post: https://diysolarforum.com/threads/does-anyone-need-premium-li-ion-battery-to-diy-their-solar-system.7396/ And for datasheet of CATL LFP 280Ah, pls check: https://www.notion.so/CATL_280Ah_Cell-383e8dcebec34a41bc50765828c2de3d

i repost my thread here again, if anything improper, pls let me know. https://diysolarforum.com/threads/does-anyone-need-premium-li-ion-battery-to-diy-their-solar-system.7396/

Hi, everyone, i just come up with this forums and very excited to see many of solar geeks here. i just post a thread, pls check. wish i can bring you some more useful info and products. Cheers https://diysolarforum.com/threads/does-anyone-need-premium-li-ion-battery-to-diy-your-solar-system.7396/

This forum actually enlarged my horizon, and i found there are so many solar geeks here. Thanks to Will Prowse, you really do a great job. i come from China, and has been working in Li-ion industry for more than 10 years, here i found many friends are looking for Li-ion battery to DIY the...
