RRedpacket replied to the thread Fifth Wheel RV Build.Any reason you're not looking at large prismatics from day one? Might be more robust with better capacity? This guys does lots of...
-
RRedpacket replied to the thread Realization About Buck/Boost Converters While Developing My First Power Box.Like nz_lifter suggests above, it should be possible to have a process where: - on connection, measure connected input voltage with no...
-
RRedpacket replied to the thread 18650 Harvesting Flow Charts.I've updated the flow chart to larger size & included IR testing. Let me know any thoughts....

RRedpacket replied to the thread Batrium and Australian smoke detectors.I googled for "smoke detector with alarm contacts" & there where lots, seem more expensive than the regular ones though.. Might also be...
-
RRedpacket replied to the thread EVE 280Ah LiFePO4 Review (Dongguan Lightning New Energy Technology).OK the voltages you are using are good. The swelling is not so good - that's probably what the smell is from, ie they are venting some...

RRedpacket reacted to LithiumSolar's post in the thread EVE 280Ah LiFePO4 Review (Dongguan Lightning New Energy Technology) with
Like.
After seeing numerous people talking about EVE 280Ah prismatic batteries, I decided to order a few and start exploring LiFePO4 more... -
RRedpacket replied to the thread Pack Fusing / Fuse Wire / Failure.Could the CID's on some have opened?
-
RRedpacket replied to the thread EVE 280Ah LiFePO4 Review (Dongguan Lightning New Energy Technology).What voltage do you charge them to? Any signs of swelling?
-
RRedpacket replied to the thread only cells in particular position is discharging. Why?.The strips may be too thin for the current. At 500W, 48V system, that's approx 10A Depending on voltage drops and the BMS connection...
