Idiot's guide to a self build battery
Re: Idiot's guide to a self build battery
I don't know if it's been posted before, but in case anyone else is thinking about placing the cells on their sides, the way Joeboy has done it is the best way:


38m Barge, Solar (10.6 kWp), 26 kWh of LFP, 50kWh Akvaterm Thermal Store (750l)
Victron Quattro 8 kVA, CerboGX, 3,500L STP, 57kVa Perkins

Re: Idiot's guide to a self build battery
A nice wee morning, spaced out and strengthened the board then stained and fixed to wall. All from stuff lieing about from other projects.



Spent about a ton on material for the frame build, clamping rods, cables ordered too. Just to buy a 1/2 sheet of engineered board and can get going with that.
Isolation switches arrived today too.

Had a decent amount of bits & Bob's left over from the last 2022 pack that will be used on this pack, i like that.

Re: Idiot's guide to a self build battery
To keep the info flowing. Selina Li at Deriy just got back to me 23 days late and more expensive than Colin Deng.
Worth bearing in mind if the reader has a battery order planned.
