NOTE:Incorrect installation of 2200uf capacitors or using voltage higher than 14.6V will greatly increase the risk of burning the power tube.

We recommend using 30-45AH performance lead-acid batteries, eliminate or replace the old battery generally can not reach the load requirements.

If the battery capacity is greater than 45AH, it is recommended to extend the input wire by 80cm to avoid burning tubes due to current overload.
