    MPPT + DC-DC = (cheap) B2B

    Interesting, even as a non electric guru, so here are a few simpleton thoughts. Alternator is a scary word to all the Battery boys. Will this protect against any possible issues inherent to an alternator connection? When I turn the power off in my Camper, I assume the Batteries are not being...

    LiFePo4 charging

    StarkPower also recommended absorption V set to 14.4V & float set to 13.8. Top balancing as a term makes sense. I never considered any different setting but it makes sense based on active use vs non use. I am fine with my float V set for now. My max absorption time is set for 6 hours. Is this...

    LiFePo4 charging

    As another reference point (post #16) my absorption is set to 14.4. Both my batteries (in parallel) float @99% capacity when full. This has been what is shown as “fully charged” as displayed by the internal Bluetooth module in each Batterry. On 08/22/19 the resting V was 13.48. On another post...

    LiFePo4 charging

    X2 on being a science guy, just not an (learning) electric guy. A sincere Tip of the Hat for building a Battery.

    LiFePo4 charging

    Followed 2 linked, long threads (honestly kind of hi jacking the latter thread) a few years back, previous to my LiFePo4 purchase. The OP was having mysterious V drain with his LFP4 Battery. He narrowed the timeline to normal V at night, abnormal & low V in the morning, that was not applicable...

    LiFePo4 charging

    I had a crisis last Spring with my, 1.5 year old, LiFePo4 100+50Ah parallel system. My Camper was undergoing an inside shop buildout &, I don’t know how, my Batteries somehow were drained completely. 12V socket use probably. It was scary. At first they were very slow to charge from Solar. The...

    New Battery

    My .02 would be to use Sterling/Solar or just Solar. After having several chats (Sterling, Stark, Relion, LifeBlue, Torque, Bioenno, BlueSea) all the Battery boys were queasy with a DC-DC Truck-Camper connection. Sterling, with his explanation, simplified a bit, impressed me. Noted, I do not...

    New Battery

    Here is another possible choice, it contains internal Bluetooth. “Assembled” likely in China, not assembled in the USA, 5 year warranty. I think pretty much all cells, everywhere, originate from China. Quality internal BMS is an important import from China as well. I would love to know if that...

    New Battery

    I would advise making sure that you can add a newer (different) generation LiFePo4 to an older generation. Running them together in parallel, make sure it is recommended. It could affect life span. If you will be connected to your truck battery for recharging, check on your alternator about any...

    Building a portable Power Box - last updates

    Touché, re the camping buddy, patience too. :) I got all the parts ready now (I think), just need to make efficient & prudent wiring scheme. I want it to come together sooner than later.

    What does everyone use for camper steps?

    3 step Little Giant. Would like it to be smaller, but it offers tremendous stability, wide steps. Last in my Camper, first out. The top “handle bar” folds down out of the way. It fits my truck just right. FWC does offer a hitch mount step-up...

    Building a portable Power Box - last updates

    With electrical DIY I am ”pretty” good if I have a recipe. Fully understanding the overall, initial design, not so good. I have been looking at YouTube for ideas. Most videos seem like guys trying to outdo one another. I think my needs are fairly simple. Here are my perceived needs &...

    Camper Windows?

    Consider no-see-um screen netting for the soft windows if travel takes you where they can be prevalent. I wish FWC had done so.

    WTW Gathering - July 2019 - Tahoe Sierra Area

    Wow, sounds like some good camaraderie! Missed the heads up on this one. I’m on & off with WTW depending on Grandkids & our travels. How could our Camper get in the rotation, if, there is a future gathering? Thanks - Mark

    Elec-trickery help

    Just a note of info here ... Lithium Batteries for motorcycles vs LiFePo4 deep cycle, lithium Ah storage Batteries, are different animals. Only use a LiFePo4 battery charger, only use a solar controller with a LiFePo4 setting, preferably of high quality. Do Not connect to your vehicle...

    Grandby Shell build, it takes a Village, a bit more install info, Zero Declination drop down shower

    The same lead Tech, Max, also works there, same State, N.C. I want to make clear I am only reporting my experiences for the edification of WTW. I have no recommendations to give, I have no history with this, buyer beware. I have taken a full dive into LiFePo4. May it reward me with reliable off...

    Grandby Shell build, it takes a Village, a bit more install info, Zero Declination drop down shower

    This is a new purchase, a LiFePo4 50 Ah Battery, that will be multi-tasked. My truck, Camper, canoe, & a bear box, in high bear population areas. I am going to make a Power Box which will enhance portability & multi use. This company, Torque Power, I think, is somehow related/off shoot to Stark...

    Grandby Shell build, it takes a Village, a bit more install info, Zero Declination drop down shower

    Here are screen shots from a Smart Bluetooth Victron solar controller. These were both taken late yesterday, Sun was low, all power to the Camper turned off. Everything at full capacity, 2 -120W panels not engaged. #1 Device status shown in 3 parts ... Solar W output, Solar voltage & current...

    Grandby Shell build, it takes a Village, a bit more install info, Zero Declination drop down shower

    StarkPower Bluetooth LiFePo4 App. I have 100Ah & 50Ah batteries, connected in parallel, in my FWC battery box. I purchased both about 1.5 yrs ago, same generation, parallel compatible. I am not that handy. When I found out that internal Bluetooth existed in LiFePo4, I saw it as an opportunity. I...

    WaterPORT Daytank 3.8 gal port/press H2O - first impressions 7/26

    The tank is actually food grade plastic. Here are my thoughts after giving it a test run today after receiving it yesterday .... I posted this initially because Costco was offering it for $129, $30 off, their regular $159 listed price. The bundle that Costco offers is equal to $209 on the WP...

    WaterPORT Daytank 3.8 gal port/press H2O - first impressions 7/26

    WaterPORT Daytank 3.8 gal port/press H2O - first impressions 7/26

    This system & manufacturer offers a lot of versatility, it hits the notes for me. The hitch mount offers an instant solution while I consider another option. I have looked at other pre-built systems & DIY options. Coupled with a drop down shower curtain, using info from a recent video post, I...

    Grandby Shell build, it takes a Village, a bit more install info, Zero Declination drop down shower

    Hot glued onto fan housing. Drilled a hole for new control knob. I found it easier just to bypass the wiring for the old 3 speed knob. I left it in place & did not attempt its removal, less collateral aftermath. Got great tech consultation from my son on this attemp. The above link is excellent...
