Battery-powered T12 Soldering Station Dedicated 6-series Lithium Battery 24v25.2v Balanced Protection Board
If using a normal double-height height is not installed into the shell, because the shell's internal space is only 32mm or less. And even if you use spot welding double-cross point, the fixed is only plastic, but the battery weight is heavy, fixed with glue is simply not fixed up. So I specifically customized this special balance board.
The balanced board uses two BYD battery management chip BM3451, this chip won several international awards, perfect protection, low self-consumption electrode, not the market with TL431 or domestic special chip to do a balanced protection board comparable.
Over current, over voltage, over temperature, short circuit, low voltage protection and other protection should be complete. There is also a function is to detect circuit break protection, the market is not a lot of balanced protection board, if the test line will lose the protection of the break, quite dangerous.
Overcurrent protection: 10A, the user can change the sampling resistance to increase or decrease the protection current.
Overcharge protection voltage: 4.2V
Over discharge protection voltage: 2.8V
Balance starting voltage: 4.18V
Charge overheating protection temperature: 55C
Discharge overheating protection temperature: 75C
Attention when installing, take the line, before and after the baffle is installed, and then make a mark on the front end of the board, and then open the tailgate, pull out the balance board, and then use the tool to mark a fixed slot to punch a block mouth, Prevent the board from sliding forward to the front control panel. Because the weight of the board after loading the battery is still large, the general way of fixing with glue is ineffective. Remember!!
