Some interesting conversations about batteries and chargers
I also been running around with problem solvong which are the best
Garagedoor motors 2× 12 Vdc GEL (connected in series to make 24vdc ) was my solution to garagedoormotors
I did a conversion with two Uniross lithuims ...build into a plastic IDS alarm box connected to the gatemotor (ETdrive 300) and had no problems so far )
For gatemotors ...lots of lithuims ...ended on Blue Nova (as it has a BMS ) and Uniross as well ....
Alarm systems rather go the GEL way ...2 × Gels connected in parallel will work better than any lithuim ...thats just my experience lot of suppliers say alot of different things (some would even tell you rather buy from them than any other supplier just to make sales...and thats just BS )
BUT there are suppliers that are honest enough to help to get the right advice and backup solutions...
Then again ...I advise my clients with the budget and bigger traffice gatemotors to rather go the solarpanel charging system with backup than going lithuim...bit more expensive but resolves so much more problems in the future
