1.) Program safe against diode damage. In the standby status, the voltage is output at 31V. If the battery is connected in reverse, error should happen immediately.
2.) Inspection for diode short circuit "SHORT-CIRCUITED"
3.) Lithium battery and new algorithm for charge protection Without connecting the balancing cable to the charger, during charge, 1cell voltage was shown on the screen. This is now fixed.
4.) CV charge voltage STEP change from 0.1V/Step to 0.01V/step
5.) BALANCE operation Even without connecting the battery cable to the charger with connecting only the balancing cable to the charger, balancing should be activated.
6.) Factory setting change LiPo 105%, NiMH 120%
7.) Pb battery charge voltage change Now, change to adjustable 1.8 ~ 2.3V/C ,10mV/C Step from the fixed voltage of 2.334V/C.
8.) Trickle charge for NiMH batteries in discharge match mode, if the cell voltage does fall under 1.1V.
9.) Program protection patch.

Program is changed from V1.2 to V1.21
Fixed the wrong balance reading voltage like showing 0.18V of 7cells when 6cells are connected.
Discharge cutoff voltage for NiCd and NiMH chang e from 0.1~1.2V 0.1V/step to 0.10~1.30V 0.01V/step.
NiMH matched function
MATCHED DISCHARGE -> DELAY -> CHARGE
Balancing should be working at the selected matched voltage during delay.
Improved balancing algorithm Trickle charge in balancer discharge mode
LiPo Auto Current Reduced current to 1/2 current
Wrong error message No balancer wire connected the user does adjust... Although this version is v1.21, this will be shown as still v1.2 on the screen.

Firmwareaupdate V1.3
When battery is disconnected in Delay mode, input error happens at the moment. Now, Open error should happen instead of Input error.
In the User Name Edit screen, dial selection mistake. Press and move the dial to the counterclockwise direction, it moves to 7th line.
Cable connection improvement
Improved the connection condition between output cables among channels and balancing cables.
