    Givenergy 5kw hybrid inverter working with DIY battery storage

    If anything is getting warm to the point you can feel it you are already well beyond what the cable and connections should be carrying in a building wiring system. 25mm^2 is massive and should be fine. I would check for any software limits on charging by thoroughly reading the manual, or...

    12V van setup battery suggestions

    Unfortunately all these brands are juggling faster than folks can review them. That's not even considering supplier changes for same models/brands. From what I have seen of the reviews going around unless the reviewer buys a battery and you buy it within a few months the review could very well...

    How to Fix Self Heating Batteries that Won't Self Heat LiTime AmpereTime

    Does the battery charger have a low temp cut off that prevents charging on its own? Is the charger designed to handle a "heater only" load while the batteries warm themselves? or does it stop trying to charge if it sees no big current flowing while attempting to charge? Crazy number of...

    Are these batteries usable?

    They do make cylindrical cell LIFEPO4 chemistry but they are not common. Knowing the chemistry of the cells is important to determine the charge/discharge voltage levels. If a single cell is damaged it will drain the whole set of parallel cells down with it causing damage to all unless it...

    Get smaller 4-100ah or 2-200ah batteries?

    Consider the tradeoffs of 12 or 24v batteries. 12V super common and could have other uses but you have to keep them somewhat balanced between packs. Especially if you intend to use the full capacity routinely. 24V batteries you get zero balancing hassle but more limited applications beyond...

    Are these batteries usable?

    If the units don't turn on and all the cells are above the cutoff threshold and the electronics do not appear to be fixable I would begin the process of removing all the electronics and BMS. Testing every cell with at least a volt meter, then load/ discharge test and some charging. Preferably...

    Givenergy 5kw hybrid inverter working with DIY battery storage

    What size cables are installed between the battery and the unit? Edit: After 4 websites, several data sheets and manuals I can not find ANY DC battery voltage spec. Very odd.

    Anyone have experience with the ECO-WORTHY 48V 50Ah 2560Wh Golf Cart LiFePO4 Lithium Battery?

    ECO-WORTHY 48V 50Ah 2560Wh Golf Cart LiFePO4 Lithium Battery I am looking to build a 3kw EG4 system, but do not need very much battery capacity or the full 3kw of power. Is this battery worth a flip? There does not seem to be very much ECO-WORTHY 48V info out there, especially on this little...
