    the easy way to keep your cells balanced is...active balancing

    Did you keep the cell monitoring cables the same length for each cell, or trim them to length from BMS? I was planning to trim mine to length from BMS, so that the nearest cell would have a shorter cable and the farthest cell would have a longer cable. That would keep my wiring loom nice and...

    "Smart Balancing" - A better way to maintain cell balance.

    Thanks for this explanation. Sounds great. I bought a BMS (Heltec #1026) with ports for CANBUS and RS485 (aka MODBUS?) and a Sol-Ark 12k with support for CANBUS/MODBUS, and I hope to eventually get the inter-communication working, although the documentation seems lacking. In the meantime I...

    the easy way to keep your cells balanced is...active balancing

    Thanks, I just received my order a couple days ago. Same comical misspelling of "Balance" and documentation is weak, but otherwise the build quality seems solid. I need to get some cables and accessories this week, but hopefully will get my batteries assembled and ready for some testing soon.

    Looking for a BMS that won't limit my charging or output

    Arguable. My grid-tied solar array only provides 70-80% of my power needs (annual average). If a hurricane comes through and knocked out power for a week+, my batteries might start getting pretty low. It would be nice to be able to run a generator periodically to top up the tank. In that...

    the easy way to keep your cells balanced is...active balancing

    Anyone have experience with the HelTec SmartBMS? BMS with built-in active balancing and supports CANbus/RS485 communication. Seems like it would be good. I'm thinking of cancelling my order for Overkill 48V BMS and get these instead. The website is hilariously terrible. But if the product...

    Sol-Ark with GYLL Batteries?

    I'm a newbie here, but my understanding is that if these batteries are wired in parallel then you do multiply amp rating and watts rating, while voltage rating remains the same at 48V (51.2V). So yes, your battery array is 300Ah and 15360 Wh (51.2V * 300Ah = 15360Wh). Again assuming they are...

    Are Vglory Batteries the same as Gyll Batteries

    Similar product from “Greensun Solar” - no idea on price, availability, or quality. https://www.greensunpv.com/48v-100ah-lifepo4-battery-pack-5kwh-lithium-ion-battery-51-2v-100ah_p145.html...

    Battery for Sol-ark

    Well, that’s a whole other issue. As far as I know, signature solar is the exclusive vendor, but they haven’t had them in stock for weeks and aren’t accepting backorders. I read in another thread that they might get more in 2-3 weeks, but idk. ?‍♂️ https://shop.signaturesolar.us/pages/eg4...

    Battery for Sol-ark

    How's that working out? Easy integration, I hope? In another thread, someone said that Fortress eFlex supported CanBus communication with Sol-Ark, but not the eVault (yet). Is that right? What price did you get on the eVault, if you don't mind saying? I ordered a bunch of battery cells to...

    LFP power vs energy density - know your cells!

    All true, but @Steve_S was referring to home battery systems with super caps. I assume to handle load surges like HVAC kicking on, or a water pump? In that case, I suppose that the rate of super capacitor self-discharge would need to be considered as part of the system design.

    Sounds like a great idea. Is anyone DIY this yet?
