Greetings. I have a small camper on which I have and Eco-Worthy 160w flexible panel. The specifications are: 160W Max. power Current(Imp) 9.06A Short circuit current(Isc) 9.60A Max. power voltage (Vmp) 17.7V Open circuit voltage(Voc) 20.68V Needless to say, after 3 years...

I posted a week or so ago that I thought I had a failed cell among the 4 120Ah cells in my DIY battery. In my haste I ordered a single replacement. Only after returning home from our long trip did I determine that the BMS had failed. I now have a working battery again (with new BMS), as well as...

Greetings. I assembled a 120Ah LiFePo4 battery about 2 years ago, and installed it in my small camper. It has been a great performer, with few issues. That said, during a recent 6 week road trip which saw many days of little to no sun, the BMS shut the battery down until I was able to supply...

Greetings. I recently purchase 6 250 watt panels to affix to my garage roof where I have no utility power. The panels specifications are: Rated Power: 250W Open circuit voltage (VOC): 37.6 V Max power voltage (VMP): 30.3 V Short circuit current (ISC): 8.85 A Max power current: 8.27 A The...

Greetings. I am far from an electrician or electrical engineer, but with the help of this forum, and the published videos and book from Will Prowse, I assembled a 100Ah DIY battery for my little 13' Scamp camper. It is charged via a 160 watt panel, Rich 20 amp charge controller and Daly "dumb"...

Greetings. I have a single application requiring 24v. My small camper is setup entirely for 12v, so I purchased a 12v to 24v converter. My question is whether, when doubling the voltage I will reduce the amperage by half. Thank you.

Greetings. I have installed a Dometic/Waeco CR50 12v refrigerator. I've currently got it directly connected to my 100Ah LiFePo4 4s battery pack. I wonder if it is recommended to connect the negative to my Daly 100a BMS. The refrigerator itself has a low-voltage cutoff of 10.7v which seems to me...

Greetings. I posted a couple of days ago in the wrong sub-forum about an issue I'm experiencing. I hope I can get some insight here. My Scamp 13' foot camper has a 160w flexible solar panel, 100Ah DIY LiFiPo4 battery with Daly 60a BMS, managed by a 20a Rich Solar charge controller, and a BattGo...

Greetings. Please be gentle. I have for some months had great success with my DIY 100Ah battery and 60A Daly BMS. I recently decided to install an AiLi battery monitor. I noticed within a day that my battery percentage was falling. I have the battery positive connected to B+ of the shunt and...

I wonder if we might have a thread where members can show the assorted battery-powered (or hand) devices they use that are stand-alone but can be solar charged. A post by "tigerbiter" regarding powering his coffee grinder got me thinking about how I've managed to deal with the frequent power...

Greetings. I have completed the installation of a 160 watt flexible panel on the roof of my Scamp camper, connected to an MPPT charge controller and 120Ah LiFePo4 battery bank. Given the drawbacks of using a fixed panel in inclement weather or shaded spots, I'm wondering about the possibility of...

Greetings. I will be traveling abroad for the winter, returning in April. I have a DIY LiFePo4 pack in my camper. Nighttime temperatures through the coldest part of winter may reach as low as 15f/-9c, although daytime temperatures are likely to always be above freezing. Is it best to disconnect...

Following Will's video highlighting the Moes Automatic Transfer Switch, I decided to setup my office to run on solar, utilizing a couple of older UniSolar panels and the first LiFePo4 battery pack (used K2 Energy 12v/90Ah) I built. It works beautifully, although I have to raise the bottom...

I've been testing my build for 2 weeks and am more than pleased with the outcome. My 1986 Scamp now features a 160 watt flexible panel and a 12v/120Ah battery which I built, guided by Will's videos. It performs fabulously well. The Waeco/Dometic refrigerator, furnace fan and LED lights seem to...

I saw a Facebook Marketplace listing near me for a pallet of Jinko 360 watt panels. They are described as "used, like new", with a selling price of $175 each. Does this sound like a decent deal?

Greetings. I'm decidedly new at this, but have now completed two DIY battery banks. One is a 12v 90Ah, the other 12v 120Ah. The 90Ah was my first attempt, using 90Ah K2 cells. I employ an Eco-Worthy 40a charge controller. Because the battery would not fit in the compartment on my camper, I...

Greetings. I'm wondering if it makes any sense to run both a Daly BMS and the small active BMS together. Do they just mimic each other's functions or interfere with one another? Thank you.

In "Mobile Solar Power Made Easy", in Will Prowse' description of how to bottom balance, he suggests that we "...put entire battery on a charger and charge up to 14.4. Check the cell voltages while charging..." May I ask how it's possible to get the voltage that high in the process of bottom...

Hello all. My LiFePo4 (12v/100Ah) is built pretty much along Will's guidelines to be used in my little Scamp camper. I purchased a Daly 100 4S BMS. I also run a Waeco Coolmatic Cr50 refrigerator. I have the B- of the BMS connected to my 12v distribution panel, but the refrigerator will not run...

Greetings. I just completed my first 12v 100aH battery bank using K2 Energy cells. My desired location for placing the battery in my small camper is barely tall enough to accommodate them while upright. I wonder about the feasibility of laying the battery bank on its side (edge). There is scant...

I am a recently-retired educator and technology director. After 18 years living and working abroad my spouse and I settling into our old miners cabin in beautiful Bisbee. I started watching Will's videos last year while in Malaysia and determined that my first retirement goal would be to get my...
