Stephen, I really am not up to snuff on LiFePO4 Batteries. What makes Battleborns soooo much more expensive and do you think they are worth it. I know that's a rhetorical question since you didn't buy them, but what's your opinion?

The thing that can make the decision to purchase Battle Born battery is that it is a US company. Therefore, warranty issues are likely to be addressed more quickly. When it comes down to it, I believe the cells for both are likely made in China as there are no US LiFePO4 cell makers that I could find. What you pay for with Battle Born is the name, reputation, and post-sale service. I spent less money, but I am taking the risk that if something goes wrong, that I may or may not be able to get service. There is a US contact, JITA-US@outlook.com. However, whether that is a reliable contact remains to be seen. The manual lists the following for contact information:
Manufacture: Shenzhen Lijingte Technology Co., Ltd Address: 5th Floor, Shangpinju, Xinfu Harbor, Baoan District, Shenzhen Telephone: +86-0769-81238456 Zip code: 518100 Anyway, it is too soon to give an objective evaluation. I'll know more after I get the initial deep discharge and full charge cycle. The manual says that there is an after-sales service center in California, but it does not give that address or any other contact information other than the outlook email address. |

FWIW, I have been looking at LiFePo batteries for a little while, and Shenzhen is just about one of the largest makers on the planet. It may just end up being the battery we choose if (when?) we decide to switch over.

Up till recently the lowest cost way to get a lot of Li battery capacity has been to buy salvage battery modules from wrecked EV's. Good 5.2kwh Tesla battery modules go for around $1300 so about $250/kwh.
But StephenH's new battery cost just over $300/kwh. Considering that with the EV modules you have to buy and configure a BMS as well as convert to a higher voltage I think the new 12V Chinese battery route is the way to go, unless perhaps you really want to go to a higher voltage anyway (which you would probably want to do if you started running heavier loads like the a/c). Battleborn at $750/kwh isn't even in the running. I can't see their business model being viable much longer, so folks considering then because of potentially better post sales support should consider the possibility that the company might not be around long term. |

Thanks. I got done with a deep discharge which in my case, was down to 55%. The original reading of the battery was not at 100% (200AH) on the initial charge. After a discharge to 55%, it recharged to 191AH, or about 95%. I am going to write to see how deep this battery needs to be discharged to get the readings to be accurate.
It also might be a meter problem. I may need to factory reset the meter, not just change the capacity.

How are you determining when you're at 55%? |

I discharged it (running my new refrigerator for a day and a half) until the meter said I had about 110AH remaining. I used a calculator and figured out what it was at 55% and the meter's percent reading agreed with that. Since that matched up, I stopped discharging (turned the refrigerator off) and started charging. When it stopped, it was at 191 AH, or 95%.
I wrote JITA-US to ask about how deep a deep discharge needed to be and why the meter was not reading 200AH when fully charged. I'm trying to find the manual for the meter to see what might need to be programmed there besides changing the capacity.

At the start of your discharge test your monitor thought you had 200AH? Some amphour capacity meters use a moving average approach to determine battery capacity. Effectively they need some cycles to "learn" what capacity the battery has. So they aren't very accurate to start with. A 5% error isn't that much really.
