Secondly, during the guarantee period, we will send you with new order for small quantity. For defective batch products, we will repair them and resend them to you or we can discuss the solution including re-call according to real situation.
Q9. Why the voltage and current reading on charger LCD is not accurate?
A: Voltage and current are calibrated before ship, otherwise the charger don't work, so please check the output wire connection, when distance between the charger and your battery is a problem, please lengthen AC cable NOT lengthen DC cable (output cable). the 1 meter (10AWG or 8AWG) output cable length is suggested, over 1 meter, will affect voltage and current accuracy especially at over 30A 1500W.
Q10. Why don't charge my battery?
A: if battery voltage reading on LCD under the lowest voltage that limited by charger, or the battery is over discharged, or cell count setting wrong, or battery connection loosing, the charger don't charge. so check battery connection, first confirm voltage reading on LCD is correct or not (generally lower 1-2V than battery actual voltage), if not the charger don't charge (display battery voltage low), if yes, please set charge parameters and then start to charge.
Q11. Can the charger communicate with other brand BMS?
A: yes, there is a control port on the charger, for details please contact us.
Q12. How to prevent any cell over charged during charging?
A1: Fit with BMS, BMS cut off charging by disconnecting charging circuit, such as disconnect DCC, relay, SSR. Battery switcher.
A2: fit with Chargery BMS, BMS control charging current till zero. Don't cut off charging repeatly, shorten charging time and save DCC, relay, SSR, and any switchers.
Q13. Can the charger work alone without BMS?
A: yes, but the battery maybe over charged.
Q14. Can the charger monitor each cell voltage?
A: No, the charger monitor total battery voltage, charging current, charging time and capacity charged, cannot monitor each cell voltage, so wihtout BMS or other protection board, the battery is unsafe during charging.
Q15. Can the charger be controlled by external device?
A: yes, external device can control charging current even cut off charging. it is only for A version.
Q16. Is the charger compatible with Plug and Play functionality?
A:yes, if you set "Auto charge" to ON before charging and charge for more than 1 minute, the charger will remember the settings. Next time you connect the battery to the charger, it will automatically charge using the previous settings. This mode is called AUTO charge mode, which works like a normal or general charger.
Q17. Can the charger charge battery on power supply mode? Or why not charge battery with power supply (PSU, SMPS, or adapters)?
A: charge any battery on power supply mode is not suggested. it is dangerous to charge battery especially Lithium battery with power supply.
CHARGERY charger such as C10325,C6830,C3060,C6050,C4012B, is not just a power supply unit, but also a charger that can operate in three modes.
Firstly, it can charge a battery in Normal Charge mode. This requires selecting the battery type, setting the cell count, charge current, end current, end voltage per cell, and others every time.
Secondly, it can charge a battery on AUTO mode. When charge parameters are set, and AUTO charge is turned on, the charger can automatically charge according to the set parameters. This is very convenient, especially when charging the same battery repeatedly.
Thirdly, it can function as a power supply unit. However, to do so, the output voltage and maximum output current must be set.
When a battery is connected to the charger, it is assumed that the intention is to charge the battery. In this case, Normal charge mode and AUTO mode are appropriate. If the PSU mode is used to charge the battery, all charge parameter settings are ignored. As a result, the charger will not stop charging or display "DONE" when the battery is fully charged. This is because all PSUs do not work at CC first then CV and stop charging like a charger does, even when a battery NOT other any device or load is connected.
When the charger operates in Normal Charge or AUTO charge mode, it first measures the battery voltage and compares it to the set parameters. If they don't match, the charger will not charge the battery. For example, if the battery is a 10S Lipo battery, the minimum voltage is 27.5V, and the maximum voltage is 42.0V. If the voltage reading on the charger's LCD is 45V or 20.0V , the charger will not charge. However, some BMS systems have a charging switcher that is turned off if without charging voltage detected, but the switcher OFF status prohibit the charger obtaining the battery voltage, resulting in battery voltage reading on charger LCD is zero, showing battery voltage low and don't charge. At this point, if alternate PSU mode, the charger output a voltage according to the voltage setting, the BMS will measure the voltage and turn on the switcher, resulting in charging current flowing into the battery. Although it may appear to be charging, it is not safe.
As you know there are some chargers output a voltage directly when the power switch is turned on and without battery connections, these chargers can work perfectly with the above mentioned BMS systems, charging the battery directly without checking the battery voltage. However, this is not safe if the battery is over-discharged or connected to the wrong type of battery, such as a 12S charger connected to a 10S battery.
