I have a Temco hammer lug crimper I bought a few years back based on Will's web site recommendation...

If you were to choose between a laser welded stud, and female threaded terminals on 280ah EVE cells, which would you choose and why?

Are there any Battle Born type battery terminals, that can be used on a DIY lithium build case?

Has anyone installed the EG4 server rack batteries in an RV? If so do you have pictures? Im looking for mounting ideas

I am looking for REALLY flexible wire for my solar suitcase. I am currently using Rich Solar wire. And while it may be flexible enough for a permanent installation, it is not for a portable panel. I keep it coiled on the back of the suitcase when not in use. And it keeps that coil memory. It is...

Looking for info before I install a DC to DC charger for my travel trailer. Bigger may be better for quickly charging the batteries. But my concerns are over taxing the alternator or tow vehicle systems. Where can I find info on amperages safe for my tow vehicle?

Is anyone using an RV wind turbine that is small enough to be easily portable and put up and take down, but effective enough to supply 100-300w?

I bought 100ah cell from Litto Kala on Alix. I top balanced to 3.6v with an iCharger. (in progress shot) I put the cells together in series, with an Overkill BMS. I drew down to 0ah (reading the OK BMS) with the cells still at about 2.9v. So I was pleased. When I went to recharge, the cells...

I decided I was going to use some flexible cutting board as cell insulators. They are thin, strong, HDPE plastic. I cut the HDPE to the length of the cell, plus the studs. I clipped the corners for buss bars I drilled a hole, and cut a slot for BMS wire management I think it worked out pretty...

I can wire the balance leads for a 4s bms in my sleep. Pack negative is named cell one. The pack main negative gets the first lead. The every positive in order, gets the next 4 leads. Pack negative then has a balance lead on the pos and neg. The other cells each get only pos. Some vids on the...

The short answer is they look pretty good. Pictures are mostly screen grabs from the video. The cells are top balancing now. As I write, they have been charging at 10amps for 4 hours with almost 40ah injected

What is the optimum length for terminal studs/grub screws, to get buss bars, balance leads, and load leads on the studs?

Does someone have a good app that helps you most effectively point your ground panels by location and time of year? I am hoping for an app that would help with the direction to point. And then angle using the phones accelerometer

I am building a smaller solar generator/power station. I am waiting on 100ah cells to build a 4s battery. My biggest load will be (at current plan) a 500w inverter. Then I will have a SCC, and various 12v/USB connections. So nothing crazy in size. But I am also on the hunt for a new travel...

I'm looking for a surface mount for a 175amp Anderson Connector. I saw these in a random video. Screen shot for reference. Can someone point me to something like this?

Newpowa has a Super Bowl flash sale. How is Newpowa quality?

I am gathering a few pieces for my (hopefully) small, easily portable, and capable DIY solar gen/power station, while I wait on 100ah cells. I bought a fold up Rockman 120 watt panel that I wanted to test. I used my kayak battery and its remote screen monitor. I was pretty impressed with the...

I am waiting on 100ah cells to build a DIY solar generator. I bought a 500w Bestek inverter. (good ratings for a smaller inverter and inexpensive) I ran test on it. The Bestek carried the a loads very well. Even better than the rating. But it has, IMO, a high standby/idle draw because the fan...

I got an old charger out of my grandfathers barn over 20 years ago. He hadn't been in the barn much in the 20 years before that. So no telling how old this thing is. But the lack of built in "safety" is the greatest thing ever. I have brought countless very low voltage batts back to life. My...

Does anyone have, or can point me to, a chart for the Valence RT series flashing lights?

Has anyone had their ground panels or solar suit case stolen from their RV site? Maybe more importantly, does anyone have a good way to secure the panels that are just propped up on the ground? I'm looking for some good ideas to keep them from walking off, when I'm gone for a period of time...

I am looking for 100ah cells for a smaller package solar generator/power station build...

I am looking for cells in the 100ah range to build a more easily portable power station. What deals for decent quality cells, along the lines of the 280ah cell deals have you found?

I have been searching the interwebs for a good solar charging solution for the odd voltages of 4s and 5s 18650 Li-Ion packs. Suddenly I had an epiphany... or a very bad idea. Thats where a solar gawd/RC enthusiast would help I have a 120w portable panel. The manufacturer rates the Voc at 19v. I...

I want to build a DIY solar power station in an ammo can, or tool box. I have a DIY 4s10p Li-ion 18650 pack that I would like to use. Is there a small SCC that would work with the higher voltage of 4s Li-ion?

Has anyone DIYed an MPPT solar charge controller?

I have an iCharge 206 powered by a Meanwell power supply. I bought these years ago, originally for multi-cell lipo balance charging. I have used this to balance charge multi-series/parallel Li-Ion 18650 builds. I have also charged LFP batts with BMS, along with FLA batts. So I know my way around...

I am going to build a small power station/solar generator that uses Ryobi 18v batts. Why? Because I already have lots of them. I am mostly copying one that I found on this forum. He used a Victron MPPT controller, because the Ryobi chargers are all limited to 2-3amps. The Victron output is...

I have searched, but not finding. Is there a list of definitions for common abbreviations/acronyms used in the forum, or on manufacturers specs, referring to solar panels, charge controllers, and the rest of the parts of these system set ups?

I have a trolling motor set up on my kayak. I have removed the trolling motor controls and replaced the controls with a remote controlled ESC. I am powering it with dual 40ah Valence LiFePO4 batts in a Harbor Freight pelican style case. While much lighter than lead acid, I want to try to lighten...
