    Bus bars needed

    Sorry if this has already been answered. I bought 16 of the 25 amp Navitas cells from BH a while back to build a 4s4p, 100 amp pack for a trolling motor that draws about 50 amps. I have since had a spinal operation and no longer have dependable use of my left arm. I have tried to make some bus...

    Charging cell fone with 4s 18650 pack

    Thanks, very helpful. I followed the link and learned a lot about available products. I guess I need to just test the output of my particular USB ports. If they are around 6 volts instead of 5 v. If so, I probably need to use a small buck converter between the battery pack and this particular...

    Charging cell fone with 4s 18650 pack

    I am something of a novice so can I get some advice? I built a plastic ammo box battery with 18650 cells from modems as a 4s configuration which charges to 16.8 volts. I put a small socket in the lid which has two USB charge ports and a small volt meter as well as a cigarette lighter socket and...

    Replacing 100amp FLA in camper, need Lipo4 cells

    Thanks, I completely agree with your DIY assessment and that's where I am going. I have been building several variations of batt packs lately in order to run LED equipment, eg, light bars and spot lites for remote locations in rural areas (feral hog outposts). They run anywhere from 12v to 30v...

    Replacing 100amp FLA in camper, need Lipo4 cells

    My 2 year old deep cycle battery needs replacing. I am going to build something around 80 to 100 amps as the house battery. Can someone recommend the best source for affordable cells to make a drop in replacement. I built one last Christmas for a trolling motor but it seems like a lot of things...

    Cheap way to charge 28.8v, 8s4p battery pack

    I see what you are saying and respect your point. I just do not care if they burn up. Either way, I am going to learn something and its going to be where it really doesn't matter. If it works like the Israeli engineers designed it to work, I will have a workable unit. if not, it is toast. I...

    Cheap way to charge 28.8v, 8s4p battery pack

    Thank you. ----I have a little knowledge and, as you know, that is dangerous. ---- I have some devises I ordered form "china" that are cheap "buck converters". they step-down,---- and volts and amps are adjustable, with screws. I am thinking I can get a power supply out of an old computer...

    Cheap way to charge 28.8v, 8s4p battery pack

    Thanks for your concern and warning. I am pretty cautious and am aware of the cobalt drawbacks. These particular packs all have a BMS built in. I have been running a tesla "S" pack in a travel trailer for over a year and it is all sunshine for me. I am not an expert but I understand their weak...

    Cheap way to charge 28.8v, 8s4p battery pack

    I bought some 28.8v, 7.8 ah modules from battery hookup to experiment with. (https://batteryhookup.com/products/samsung-8s) . I am likely going to connect 5 to 10 in parallel via bus bars and charge then with solar panels. but, all test at right at 32.1 volts with one a 27.9v. I want to hook up...

    Shore charging 24v lifepo

    Overall, this has been a very enlightening thread for me. I am relatively new to dc power, solar and lithium storage. This stuff just seems so cool and worthwhile. I really thank you guys for putting this out there so I can pick up a little bit. Pink
