Here's the thing:
2x AGMs fitted one or both are getting sad, namely just shed power quickly under load so was asked about upgrade to Lithium, fitting or choosing a lithium isn't a problem, the van has a "BMPro BatteryPlus35 SR" (BM BP)fitted so not Lithium compatable ...........
Replacing with a BM Pro unit which is lithium does up the cost of the upgrade and is very easy being just plug and play, the limited panel watt isn't really a problem as who has ever seen 300 plus watts on their display let alone 200w .........................
The other option is add a decent MPPT solar reg with a display and turn the BM BP unit into a big distribution panel with feed to aux from load on solar reg none direct from battery and add a mains lithium charger for if ever needed but I think the unit may have a hissy and give problems to a flick the switch only type operator ...
Any other ideas ?????
I'm leaning to the completely upgraded BMS unit using a Lithium BMPro BatteryPlus 35 HA , ease of fitting and no changes to cabling and the feed to the display unit is the same so just a change pf panels as access to cable runs in walls is not possible ....................... Going to be a slightly expensive mod to replace batteries, the saving in kgs is welcomed ..... at least the new regs for lithium storage doesn't apply but will upgrade the battery compartment to be sealed anyway ................ If they decide to spend the money .......... Of course there is an upgrade option but its not a cheaper option really and I think its a modded unit anyway.
