Is a B2B charger what we need?

They appear to be roughly half the price of Li, so if they can be used to 50% of their capacity like normal AGM or lead acids that would mean they are pretty close to Li in terms of £ per usable ah. Does this sound about right?

No you can use much more of their capacity than that and still get decent cycle rates. 50% discharge “ 2000 cycles. 70% discharge = 1200 cycles. Check the graph on the data sheet. I can’t see a downside to that battery IF they’re being honest about its specs. The only advantage lithium has is they’re much lighter. £239 vs £900 for a decent lithium.

No, not bought one as I’m still stuck in Australia (Hymer is in the UK).

They do look good, quite heavy at over 31kg per battery.

Did you buy any of these Lead Carbon batteries? New technology to me too....

I'm quite keen to know how good these are, so may post a separate thread for them.
Edited: New thread here.
