   6:30 hey if you don't know how to talk about loads, surge, amp draw/support, voltage sag, etc. then don't even bring it up. One of these batteries cannot do nearly as much as you make it out.

   8:55 really? You'd ground out a DC battery, which is low voltage, and get shocked? Well shit! Better start letting electricians know they are idiots and at risk. Weird how UL doesn't require coverage for such a "dangerous" exposed terminal.

   When putting these modules in parallel, does the module voltage need to be close to each other? Or is it not an issue with these modules?

   The model without the screen has no built in circuit breaker and only a 6 year warranty vs the screen version with built in circuit and a ten year warranty. It’s not just about a screen or no screen.

   So if you want to actually use this in a server rack for home server and networking.

   What is the most cost effective UPS/charger/inverter/ (extra bonus for solar MPPT controller) ????

   I bought a EG4 battery 1.5 years ago. It didn't work out of the box. Took them 6 weeks to approve the return. Customer service was horrible.

   I can get a 310 Ah 48 V DIY battery kit with JK BMS from Alibaba including shipping for $2250 each. I won’t buy anything from Signature Solar ever again. Their 6500EX junk, poor customer service and warranty did it for me.

    Do a quick google search to learn what amps, amp-hours, and volts are. Idk how you can review batteries and not know the difference between energy and power

    NEITHER, they are OK, but the inverter I bought from them never got connected to my computer or phone, when tried to call it in There was no fixes for it!! So I will never buy from them again, But I did find another battery well more capacity LIFEPO4 14.3KWh for 1800, SO what's cheapest now?

    I have 12 of these in my 60kw solar system. Inverter is a 18kpv. 18KW of solar panels. This runs my whole house no problem. I cut the grid off 4 weeks ago I have become so confident with EG4 products. LOVE IT. Signature solar is the beez neez also. They had trouble during pandemic but this last year customer service is fantastic.

    With all volts, amps hours, watts etc equal are server rack batteries better than "regular" lifepo4 batteries for residental solar setup? Thanks

    What about cell equalizing? Active or passive? How many mA per cell?

    Why would you bother? If you are going to do server rack batteries, build your own in a DIY case and 304ah cells for 3x the output. The DIY has a JK BMS that talks to nearly all of the big inverters including EG4, and for 40% more you get 3x the output. I don't get the love for 100ah 5Kwh server rack batteries. I have 90Kwh with 6 batteries, and you will get 30Kwh for 6 EG4 100ah. Is Sig Siolar or EG4 paying you to hype this underpowered rack mount??

    Yes, it's overhyped. For less than $700 more than what this battery is selling for, you can get more than triple the capacity (310 Ah @ 48 Volts) that this battery offers in an easy-to-assemble DIY kit using Grade A EVE cells and a JIK BMS with display and active cell balancing, Bluetooth and all the desired communication ports.

    Now we need a test with all 64 together, and then find a way to max it out.

    I dealt with Signature Solar – terrible customer support. They are a drop-ship company that doesn't answer the phone. Never again. This guy and Will Prowse should not be recommending them or their drop-ship products.

    I live off grid. I bought 3 of these LL-S batteries 6 months ago and just ran a gambit of tests. Each battery has discharged 125 kWh…they still have perfectly balanced cells and 100% of their rated capacity. Badass batteries and miles better than lead acid performance. I bought the small scale off-grid KIT-E0008 from Signature Solar

    We've had our hands on the EG4 LL 48V Server Rack Batteries for a few months now. After putting some miles on them, we believe they are one of the best server rack battery options on the market, both in terms of quality and price. So if you can put up with pinching your fingers a little bit during the one time you lift the unit, it's definitely worth scooping up!
