Great peice of kit, works like a fuel gauge for your battery - much more indicative than just looking at voltage. Or hoping and praying lol.

Measures up to 100A of current draw which is sadly not enough for the new inverter, hence why it's for sale.

Bargain at £50 collected, or plus postage.
 
Someone will love this Steve. I've got the compact BM2 (looks identical) and just wouldn't be without it for accurate information and peace of mind (y)

Blimey, there are loads of similar devices on eBay for a fraction of your asking price.

And similar is the key word there. When you say fraction - it sounds like you're talking about voltmeters, which are nothing like this...

If you're talking about the 30/40 quid Chinese things (hardly a fraction) then wildebus has tested one with dubious accuracy. And good luck getting any support when it dies/ruins your expensive battery bank.

Thanks for your input lol, but it's now sold anyway.
