Hello,
I have just bought 2x renogy 260AH 6v agm to put in series on my camper trailer tongue as the physical dimensions are optimal (extra height for extra capacity within limited width and length).
The manual for the 1x 6v 260ah states (link) (pic)
My deduction is that 2x 6v 260ah in series for a 12v bank requires;
However a single 200AH 12V AGM (not my battery, just to compare) from renogy states (pic);
My question is; is the 14.2V charging voltage correct or would 14.8V be better for the longest life? I plan to use 13.5V float.
The default AGM profile on my chargers are all 14.8V. I CAN customize both my camper dc shore powered charger and the camper solar charger down to 14.2V. Both chargers have battery temperature sensors.
Thanks,
Gordon

The manual for the 1x 6v 260ah states (link) (pic)
- Cylce 7.1V
- Float 6.75V
My deduction is that 2x 6v 260ah in series for a 12v bank requires;
- Cycle 14.2V
- Float 13.5V
However a single 200AH 12V AGM (not my battery, just to compare) from renogy states (pic);
- Cycle 14.4V - 15V
- Float 13.5V - 13.8V
My question is; is the 14.2V charging voltage correct or would 14.8V be better for the longest life? I plan to use 13.5V float.
