Was that meant for me? Did you read and understand that hydrogen is only an issue ONCE you have reached the FLOAT stage (i.e. 100% charge) or if you are doing EQ?? And only if you are FLOATING above 13.8V for a 12V battery? How is he going to get fully charged and even GET to float off of that...let alone exceed proper float voltage with a controller?
Did you also understand that the hydrogen has to reach 4% and this is a tent camper?
NO I am not worried that his single 80 watt solar panel charging system is going to blow up his tent.
