A while ago I ordered (2) JBD BMS's. I thought I was ordering 8S LifePo4 Smart BMS. Instead I ordered 10S Li-ion Smart BMS. Can I use the 10S on the 8S LifePo4? I would think I would be able to modify settings to work for LifePo4, but not 100% sure. Anybody have any idea? Also - not sure...

Seems like when I add more capability, I find more and more uses for my energy. I have 24V system with (2) Victron Multiplus 24/3000/70 set up in Split-Phase Configuration. I decided to do Split-Phase as opposed to parallel configuration because with split-phase I didn't need to balance my...

I just got a Cerbo GX and hooked it up and loving it. Data lovers dream and I think it will make load management easier this winter. I should have bought it a long time ago! Thanks to @sunshine_eggo for encouraging me to buy it. My question is this. I have multiplus inverter and a couple of...

I am off grid. I own two identical 24/3000/70 Victron Multiplus'. I have only been using one over the last year or so - hardly ever need more than 2500 watts and if I do for a little while, the overload feature seems to work fine. Currently, I use the AC1 for my everyday loads on one side of...

I have a used Exeltech XP250 Inverter for sale. Its used but works great. I bought on ebay and tested it but ended doing much bigger system - guaranteed to work. Great product and great company with awesome support. $125 if you pick up in SW Wisconsin near Viroqua, WI. I can ship it to...

I have (2) 280Ah 24V diy battery packs that I have had up and running for about a year now. I am off grid and these batteries have literally changed my life in so many ways, but I have had connection/corrosion issues that seem to crop up more and more and I am looking for a solution. I am...

I purchased (2) 100Amp 24V 8S BMS from Overkill solar in January of 2021. I put them into service the summer of 2021 and they worked flawlessly until very recently where I started to have issues with one of the BMS. I contacted customer support and received some ideas, none of which worked...

I have (2) 24v DIY batteries with the Lishen 272 batteries. Both of my BMS's are the Overkill 8s models. I have been running these for 4 or 5 months now with no issues. A few days ago, I was changing a setting on BMS #1 and when it was updating the new settings, it got hung up and didn't...

Hi All, Here is my system - 24V Off Grid. Multiplus 24/3000/70, Victron Smart Solar 150/70 CC, (2) 272AH 24 V battery packs each with Overkill BMS. System is working great and I often have a surplus of energy and would like to make some use of it. When my battery is over 90%, I want to use...

I have for sale (2) KACO grid-tie all in one inverters. These are German made and still under their 10 year warranty that is from date of manufacture and doesn't require any paperwork. They were both manufactured in Q2 2013, so warranty is good until Q2 2023. They both work fine and include an...

I ordered cells in the group buy. One of the cells was damaged and Michael exchanged cells with me to give me a new one. He replaced my Lishen 272 cell with an Eve 280 cell. The Lishen's are all labelled with IR of .12 and the Eve is labelled with IR of .15 I just wanted to check and confirm...

Hello! I am putting together a diy battery pack - I have (18) Lishen 272AH batteries on order through the Group Buy and have received my tracking info (still likely 30-40 days away). I plan to build (2) 24v 272AH packs (and have 2 batteries left over to use as spares in future). This battery...

This is my first winter staying at my off-grid cabin. I currently have one string of (4) panels wires in series - a total of about 800 watts feeding a Midnite Kid CC. I am taking off for a couple of weeks and realizing that without being able to brush snow off my panels, I am likely to deplete...
