Hi guys I just bought some new 12v 100Ah LiFePo4 from LiTime. I have 4 of them. Do they need to be fully charged individually before connecting them in parallel, or can I just wire them up and charge them as a bank? Thank you

Hi guys I have a van I am currently building. I've taken on the challenge of installing a mini dorm fridge as I wanted more capacity for a much cheaper price (compared to 12v fridges and 12v chest style fridges/coolers). Yes I know they're not as efficient (although debatable with real world...

Hi guys I’m using 3 x 200w Renogy panels on my camper van; wired in series. I got up on my roof today to check things out after 5-6 months of having them installed. I noticed this on ONE of the panels. After doing some research tonight it seems like it could be a hot spot but at the time I...

Hi guys I'm building my first solar setup on my van camper build. I have 2 panels set up right now (2x200W Renogy mono panels). When I first got them, I tested the open circuit voltage and short circuit current with my multimeter. The rating on the panels is 23V and 11.05A STC. I was getting...

Hi guys I am in the process of building out my Sprinter van. I started out with the intention of using 400W of solar (2x 200w panels, optimum operating voltage of 19.2v and short circuit current 11.05A each). I ran 10 AWG solar panel wire from the roof of my van through a roof gland and to the...

Hi guys I have 3 x 200w panels I would like to put in series. Open circuit voltage is 23v on each. In the data sheet it says temperature coefficient of VOC -0.28%/ºC. Would I still be safe with a SCC that has a max 100v input? It would be 69v plus whatever margin of safety for cold weather...

Hi guys I've been reading more and more about DIY LiFePo4 batteries, and how charging them under cold temperatures (say under -5c) can actually damage the cells severely. I have a LiFePo4 powersports battery from a well known brand called Shorai that I've used for many years and in many...

Hi guys Anyone here recently bought any Docan 280 cells from Canada recently? Speaking to Daisy from Docan (who I now realize from reviews on here Docan isn't the greatest or most honest) she said they are $95 USD each shipping included from Canada to Canada. Not looking for other people's...
