    Bigbattery.com Llama 48V 115AH setup questions

    Yes, that seems right because the LAMA is 14s LiFePO4 instead of the more-standard 16s LiFePO4. I'm not sure why they went with 14s for that battery. They might have been targeting a specific market. If you're working with off-grid solar, I'd suggest going with a 16s LiFePO4 setup of some kind...

    BigBattery "OWL MAX 2" 12V 228Ah LiFePO4 using Batteries with scratched off QR code

    I believe these to be REPT 230Ah batteries. I don't know why I thought they were Lishen. I swear I saw it on their website somewhere, but must be dreaming or something as I can't find it now. My bad... Edit: I found it. The video on the product page says "Lishen Cells" but I see now that video...

    EVE 230Ah Batteries

    Does anyone have any info on the EVE LF230 batteries? Basen is telling me the LF280s are sold out, price will be going up, and are recommending the LF230s. I can't find any info (or a datasheet) on them anywhere. Thanks.

    WANTED: EVE 280Ah Busbars

    I'm aware of this. My OCD-ness wants the same on everything (original bars).

    WANTED: EVE 280Ah Busbars

    I ordered 32 more EVEs from Basen, along with a double set of busbars. I should have 16 extras if I mathed correctly. If you still need 4 more, I can hook you up when they're here (probably 2 months).

    WANTED: EVE 280Ah Busbars

    I'm looking for 16 of the busbars that came with the Shenzhen Basen EVE 280Ah batteries. Has anyone ordered these and decided not to use the hardware that came with them? I'm in the US. Thanks.

    Battery evo and big battery

    I would assume same build quality but that's just my opinion.

    Leaking Electrolyte from Bigbattery Powerblock

    I noticed the video was made "unlisted". What was the outcome? They went through 100,000 cells in their warehouse, found 11 bad cells, and the assumption is just that you happened to be so unlucky (0.01% chance) that you got a bad cell in yours?

    Battery evo and big battery

    Yes, they are the same company. BigBattery has told me this a few times now.

    ANY ONE DEAL WITH THESE GUYS - Dongguan Lightning New Energy Technology????

    Mine sat at the port for almost 2 weeks before the it was transferred to FedEx and the tracking number showed a pickup. The supplier told me there was "port congestion". I'm sure you'll see the same being the time of year it is.

    EVE 280Ah LiFePO4 Review (Dongguan Lightning New Energy Technology)

    Just an update, since I can no longer edit the original post... Rain has offered to send out the missing hardware without even being asked. I strongly appreciate the quick communication, helpfulness, and professionalism.

    ANY ONE DEAL WITH THESE GUYS - Dongguan Lightning New Energy Technology????

    I received them 2 months after placing my order. I'm not sure if that qualifies as "pretty damn quick" ;) The supplier "matched" them by grouping similar IR and voltage. Obviously the voltage match isn't worth much given the flatness of the LiFePO4 discharge curve.

    EVE 280Ah LiFePO4 Review (Dongguan Lightning New Energy Technology)

    After seeing numerous people talking about EVE 280Ah prismatic batteries, I decided to order a few and start exploring LiFePO4 more. Details of the purchase are below, along with my review and testing of the batteries. I am most interested in why 2 of the 4 sound like plastic. I'm hoping someone...

    EVE 280Ah LiFePO4 Plastic Case?

    I received some 280Ah LiFePO4 batteries and was told they are EVE-brand. The QR code does not match the format in the LF280N datasheet. Additionally, the case seems to be plastic. Does anyone recognize this format QR code by a chance? Or ever hear of EVE 280Ah with a plastic shell? When I try...

    Installed Hoffman Combiner Box on 3s5p Array

    That is a great point that I hadn't thought about - definitely should be red-taped. The wire coming off the busbar is a #6 THWN. The combined short circuit current of all 5 strings (only 4 shown here) is 47.5A - so we're good there :)
