this forum is never going to get off the ground unless we stop cribbing about lack of input and start inputting. So hear goes i have just finished my sixth lithium battery 70amph 48 volt giving me a total of 420 amps lithium which is the equivalent to 800amph lead acid and that is what i am getting rid of 8 X 6V ROLLS 650 AMPH The new battery bank consist's of 6 x 288 x 26650 cells = 1728 all spot welded togeather with nickel strips the BMS's were JDB 100amph 16S bluetooth so i can monitor each battery separately x 6 if you want to know more show some interest

thankyou i am so impressed with my hot water system 16 years and no trouble i just want to give it a service, pump is getting a bit noisey as well i would to live off grid but need a sunnier climate

i have a complete new set but i need the turn buckles ?

the reflectors are held in place with plastic turn buckles i need 6 of these are they still available

thankyou for that i have 14 that have lost there silver but they are still clear glass does this they are ok?

i have got a photo resolution problem but i will learn, when i built my solar off grid system i fitted 8 ROLLS lead acid and they have been wonderfull but they are starting to fail so the picture shows the construction of my 5th lithium 48 volt 70 ah replacement and what a project it has been using 100amph BMS with bluetooth so i can watch them if anyone is interested in this just say and i will go a bit further, anybody want some used ROLLS lead acid

hi i fitted a navatron 40 tube hot water system 16 years ago and it has been brilliant and i have noticed a drop in efficiency this last year how can i check the tubes
