FAQ

Q1. Can we put DIdifferentShould the lithium battery packs be connected in parallel or in series?
> Yes. Batteries can be placed in parallel or series by the customer. But there are a few tips we need to pay attention to:
1> Please ensure that the voltage of each battery is the same before parallel connection. If they are not the same, they will be charged at the same rate.
2> Do not place discharged batteries in parallel with undischarged batteries. This may reduce the capacity of the entire battery pack.
3> If you want to concatenate, please inform us the target capacity of the whole package. We choose the appropriate BMS for each type of battery.
4> If you are not a professional in parallel and series batteries, please do not handle the battery by yourself, which may damage the battery or reduce the cycle life of the battery.

Q2. Can we connect different lithium iron phosphate battery packs in series ourselves?
> You can buy high voltage battery pack directly from us. We do not recommend connecting them in series yourself, as this may damage the battery or reduce the cycle life of the battery pack.

Q3. Does the battery pack contain a BMS?
> Yes, our battery pack includes BMS.

Q4. What is your warranty?
