Hey Guys, I need a little help, I have a Axpert 3KVA 24V inverter, been running on Lead Acid till now, I am about to switch over to a4 x7s80p 18650 power wall and just want some validation on the settings I need to configure on the inverter, This particular inverter does have a Li-Ion option it...

So I have used rePackr to build my first 14s80p packs and ea. worked out to 180ah per cell pack, I am now wanting build my next 14s80p and I have more than enough cells, when I use rePacker there is no option to specify both cells in parallel and pack capacity, the idea is to have rePackr build...

I am planning to build a battery shed, much the same as the shed in Pete's videos, So the frame will be a 40mm x 40mm angle iron frame, to which I'll attach IBR sheets. The question is can I then attach the shutter board directly to the IBR in several places, on which I'll hang my 6 x 7s80p...

Hey Guys, So I am at a point where all my 18650 cells are ready and I'm about to start building them out and installing. My question is breakers, fuses and shunt trips. So I'll be building 2 x 7s80p banks connected to 24v 3000kvs ( 2400w ) ( 100A ) inverter, and here is my design Each 7s80P...

So I have been collecting,stripping, cleaning, charging, storing and testing 18650's till all I see when I close my eyes is 18650's My plan is to build 2 x 7S80P ( >1800mah per cell )banks and hook them up to my Axpert 3KVA inveter and replace my 6 x 100ahlead acid's. Here are a few pic's of...

Can anyone tell me from which laptop packs these usually come ?

Just what's to know at what A are we doing our discharge testing, should it be 1A or 0.5A ?

Please can someone just correct me if I am wrong here ? I have a 7S bank (7 x 80p)and I draw 70A from thebank, then the draw per pack would be 70A/7S = 10A and the draw per cell would be 10A/80cells = 0.125A ? if I am only drawing 10A per Pack then standard 10A house wire (1.5mm2)should be...

Just a quick question what size wire are you using for a fuse and where are you getting it, I am looking for 2-3A fuse wire, I not particularly keen on the glass axial fuses but I might just go that way.
