    Need a 10U or 12U rack for Signature Solar batteries

    Looking to use Signature Solar EG4 battery packs. For floor space reasons, we need a single "foot print" rack that will take 10 to 12 batteries. Does anyone make a rack that supports the weight and current of a battery system like this? Essentially a double 6U Signature Solar rack. Thanks! Sid

    Half-cell panels better than full-cell panels for shading?

    I keep seeing half-cell panels being recommended over full-cell panels to deal with shading issues. If you have any shading issues, won't the entire cell be affected? I am assuming that the paired 'halves' are adjacent to each other and are not a top versus bottom split of the panel.

    Goal Zero Yeti?

    I am looking for a better "power center" to use camping than a bunch of random power banks that are all USB based. I am initially thinking about the Yeti 200x or 500x so, nothing super big or heavy. I am looking to provide some power if my car battery is dead (I travel with a small charger car...

    Future of DIY LiFePO4 looks bleak…

    From ~95% to 100%, the voltage measurement differences are pretty small as you are way past the knee of the voltage/charge curve. At least that is what we see with our battery tests and our our batteries. My bank is ~35Kwh and a friends primary bank is ~60Kwh Flashlight and RC batteries can...

    Future of DIY LiFePO4 looks bleak…

    In my case, I have LiFePo4 batteries. If you charge them to ~95% vs. 98% and limit the discharge to 20% (from zero), you increase their "cycle life" significantly. On my new Galaxy cellphone, I did the 85% charge limit and it seems to have made a significant difference after 12 months of...

    Future of DIY LiFePO4 looks bleak…

    Tesla, Generac, and others are starting to build 'powerwalls' which work well for this type of situation. You can charge during off-peak and then consume during peak usage rates. As you add solar panels, they can charge your 'powerwall' as well.

    I could use a little help for my friend with the JBD BMS selection with battery heater pad support

    Regarding the burn through the night, his smallest battery pack is 160Ah x 16 so ~20W/hr should be manageable. He has fish that will die in cold weather if he can't keep the power on. We have unreliable power locally, going 'off-grid' protects his fish. The new battery pack won't take cold...

    I could use a little help for my friend with the JBD BMS selection with battery heater pad support

    My friend was looking at some YouTube video with a JBD BMS that had an output to drive a couple heater pads for the LiFePo4 batteries. It appeared the heater pads that were attached to sides of the batteries were connected directly to the BMS. Searching Ali Express has turned up some BMS...

    Wind generator with solar panels?

    As noted above, the voltage spikes from a Wind Turbine will destroy your Solar components if you don't have the parts in place appropriate for it. My friend runs a similar Wind Generator and has a "special" charge controller that dumps the power into a large 48VDC lead-acid battery system since...

    She can not reply via this website, if you still want to order from her, please just contact Jenny Wu. Our company has rules, same customers can not have two sales.

    I never got a response from that email address. The other one was generally answered in about 2 hours. My credit card payment was handled through the other email on Alibaba.

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    I bought 32 CATL 302Ah batteries from Jenny a while back and tried to order another BMS from Doncan later but, the order was canceled because they have a non-compete clause as explained by Doncan.

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    Docan is a separate company from Jenny. Jenny only accepts bank wire transfers or credit cards processed on Alibaba. Jenny's products can be picked up at the Docan Power storefront but, they are effectively like a drop-off site for Amazon, FedEx, or UPS.
