This is my new boat 12v 100amp lipo04 battery built outa raw cells with a BMS charged by 24v 250w solar to MTTP controler.
Next stage is to setup spit chargeing with the 20amp constant current DC boost converter feeding say 15-16v to the simple 16amp solar charge controller for the lead acid...
Yep might go down that root latter if this unrelistic.
But I like DIY as a first aproch as its cheaper (£23 for boost converter and existing old solar charger and wires)
And with DIY you understand everything which is essental liveing on a lowbudgit boat in the wilds...
After watching Will Prowse videos am doing a beginner friendly series covering this boat upgrade.
Buying the cells - the advice for buying direct from China is at the end of the video.
