Bulk/absorb = 14.2V–14.6V.
Float = 13.6V or lower.
No equalization (or set it to 14.4V if possible).
No temperature compensation.
Absorption time is approximately 20 minutes per battery, if possible.
For a 12V system, we really want to emphasize reaching 14.2V – 14.6V for bulk and absorption and float to be 13.6V or lower.

For a 24V system, we suggest a bulk and absorption rate of 28.4V– 29.2V and float to 27.2V or lower. No equalization is required, but if it’s possible we suggest 28.8V. No temperature compensation is required either, and absorption time is approximately 20 minutes per battery if that is an option.

For a 48V system, we recommend a bulk and absorption rate of 57.4V and floating it at 56.5V to 57V. Sometimes, one of the batteries may trigger a high voltage disconnect in your system. The battery’s internal BMS will help handle a high voltage disconnect. Our team wants to emphasize that, overall, there’s no harm in playing around with charge rates to optimize your system.
