Feb 10, 2023 · After the the battery outputs are combined I would have a single battery switch and a single type T fuse. The 12 V loads are a 2000W inverter (196A calculated) and miscellaneous 12 V loads for lighting, radio, and an RV propane refrigerator control board (10-20 A).

Jan 5, 2024 · Whoops, SLA battery should be gone now. I do some aggressive filtering to remove other chemistries and non-battery products, but one got through the cracks. New windows as the default behavior is technically possible, but I prefer to give the user the choice to open it in a new tab by Ctrl-clicking on the link, or in the same window if that's ...

Nov 1, 2024 · The tape is to make it easier to place and remove the battery pack into the compression mechanism and milk crate. Dang, I really thought it was a simple question and assumed I did not need to post detailed plans of my battery build.

May 3, 2020 · I did a reset on the battery and ACr went away and went to the normal screen on the controller. The controller said the battery was at 14.4v. I disconnected the battery from the controller and checked the voltage on the battery again.... 112.2v. I left it like that all day in sunshine. Checked the battery again and still at 12.2v.

Oct 8, 2020 · Attach power supply leads to battery. Turn up the amps to 1% the capacity of your battery, e.g., if you have a 100Ah battery, set to 1A. Let run for 60 minutes. Voltage should rise to near 12V. Once it's 12V or above, revert to the battery's charger. Alternatively, you could use a standard automotive-type 12V battery charger at 1-2A. Attempt to ...

Dec 16, 2023 · Hello everyone, recently i've bought from aliexpress some LiFePO batteries with the following specs: 3.2 V // 200Ah. I would like to know if they are good, on the site in the spec section is written that the internal impedance shouldn't be more than 0.6 mili ohm. The thing is that i don't know...

Dec 9, 2024 · A 300Ah battery would require 185 hours of charging at 1.3A to bring it up to 100% from 20% SoC. 12.8V = 3.2V per cell. The battery will just sit there absorbing current at that voltage until it gets up approx. 90%. Its very likely the battery is just not getting charged up past the SoC point of reaching "tail current".

Sep 20, 2019 · If you are trying to use a lifepo4 battery in freezing cold temperatures, battle born just released a 12v heat pad for keeping the batteries warm without melting the case. This pad should work for any standard lifepo4 battery. Just slap it under your batteries and connect it to 12v and you are done. I think it is over priced though.

Apr 24, 2020 · This is my install of a custom set of battery warmers from Ultra Heat. I had contacted them through email asking about a warming profile for LiFePO4 batteries. They responded with a design to my specifications, including warming pads that fit my batteries exactly. While I initiated the...

Jul 4, 2020 · I'm looking to increase both capacity and max current draw and am thinking that a 2nd 100Ah LiFePO4 battery in parallel will achieve this. Further, I'm going to try to build my own battery. I see, though, that there are options to make a battery that has, for example, 100Ah, 135Ah, 150Ah, etc. I've even seen talk of an EVE 280Ah battery on the ...
