Having worked with these a bit now I am not really convinced they are worth yet. I just spent half an hour gluing them to the batteries because they are not attached when they arrive. I am not really happy with having to use hot glue for this. Standard corage washers on the all thread extend...

Thanks to @Steve_S for this! Excerpted from another thread. "I am no expert, just a critical observer. There is far too much over concern about LFP cells sitting at "FULL" SOC. 3.65V and lower will NOT hurt the cells and over time they will self-discharge albeit quite slowly. The cells never...

This is my set up for top balancing my battery pack. It is a Riden 6006 power supply Being driven by the battery charger that I will use for the whole system that is putting out 14.4 volts. The Riden is set to 3.65V and max 6 amps. The cells are 8x Fortune 60Ah cells starting at 3.3V...

Wow. I just used the automatic style stripping tool on 16 and 20 guage today and it blew me away. Not the same one as Will links to from mobile-solar.com but basically the same. It's magical. I've used cheap ones for years as a hobbyist and after the first wire I just stared at it for 30...

If a pack is out of balance can you charge single cells using a bench voltage source clipping leads to the posts if the cell that's out? Seems like that shoudl work.

Just got my batteries from Energetech. 16 Fortune 60Ah cells for 2 packs of 2p4s 12v emergency pwer project. First impressions. Packaging is excellent. All arrived intact and no dings on the box. Shipping was fast. Customer services and communications was really good. Each cell...

Just bought the Temco crimper linked by Will and it doesn't go al the way down to #8. Blocked at #9 size by the shoulders of the pin. We'll see if it has to be adjusted with a grinder to work on 8 Guage. Bummer.

Does plug color matter for Anderson 175s? I see a lot of red in pictures. It that an amperage rating? Voltage? Thanks, -bill

Hi. I'm planning a modular backup power system for outages and camping. Here's my plan for the wiring in the battery box. Sizing this to match with a 12V 1kW inverter in a box and a 40A charger in a box. All feedback welcome. I think the terminal fuse might be overkill. Basing 1/0 AWG on...

I saw an ad for 1ga jumper cables that look like they are below cost for the wire itself. Is it OK to ask about stuff like that here or is it too much like advertising? These are 30' auto jumper cables and under $100 so this seems like a good price but it's hard to tell if they would work to...

My wild idea is a set of portabel power boxes based on 140mm US Army ammo cans as the cases. The Fortune 60Ah batteryies will fit 8 quite nicely with room to spare for BMS etc. so my thinking is: - Battery box(es) -- either 8s 24V x 60Ah or 2p4s 12V x 120Ah. Anderson connector. Probably...

I'm planning a small portable (handtruck style) system for when the power is out. Will the BMS draw down the battery (or batteries) if stored for a long period?

I'm thinking about building a portable power station around one fo the MPP Solar LV2424 inverter/charger units. I see some feedback on Amazon abotu these units where the buyer could not get the using to go into 60 cycle 120VAC mode. The seller then suggested a transformer which sounds wrong...
