 | Re: Who has used rechargeable batteries Quote: (Originally Posted by ccr_ada) to save some battery life just turn the unit off on the 6m stop and run it as an o2 manual rebreather! with the 02 button! You cant switch off the Vision unit under water. You can switch off one or the other controller but not both.Steveada  |

| Re: Who has used rechargeable batteries Quote: (Originally Posted by ccr_ada) so what units out there use rechargeable batteries as i know some do like the There is not a sharp drop off (in power). There is a battery with a certain power capacity that reduces totally linearly as the battery is discharged.horrorbus and smeg how do they get over the sharp drop off? ada The amount of charge left can be measured from the voltage, load and temperature. There is a polynomial relationship between those parameters and remaining capacity. The accuracy in which that relationship is modelled varies between different rebreathers. As the full details are published, there is no reason why anyone should have any significant error in this calculation for new product designs. Alex |

| Re: Who has used rechargeable batteries Quote: (Originally Posted by ccr_ada) so what units out there use rechargeable batteries as i know some do like the Adahorrorbus and smeg how do they get over the sharp drop off? ada the power characteristics of rechargeables are well understood, and as long as you design the electronics for a specific type of rechargeable batteries you can perform reasonably acurate monitoring. The problem is using rechargeables with a unit that wasn't designed for them. Simon A |

| Re: Who has used rechargeable batteries Quote: (Originally Posted by Simon A) Ada so is it about time AP did? the power characteristics of rechargeables are well understood, and as long as you design the electronics for a specific type of rechargeable batteries you can perform reasonably acurate monitoring. The problem is using rechargeables with a unit that wasn't designed for them. Simon A just like some of the other manufacturers it would be so handy a pack you can recharge or pop in 2 batteries best of both worlds!! that must be easy to sort ada |
