I even have a 24V 10Ah Li-ion battery that I want to charge whilst on a boat. I actually have no details concerning the boat as we are uncertain what boat we will be utilizing. I will search out the ,” 6000 cells in parallel or sequence and /or bundled” and see if I can discover this information to provide you a more clever basis to answer.
But you your objectives, a conceivable failure may end result from a USB charger one way or the other shorting the 5v enter straight to the intended four.2v output, leading to what you’re on the lookout for. The USB out from wall chargers sometimes can provide over an amp. This testing might be carried out in a stainless steel tank for the aim of analyzing the gases which might be made by way of this type of failure. We have previously induced battery failure through external heating, case crush and inner shorting.
The next technique we needed to cover is the potential for a failure in the charging mechanism that may permit an overcharging scenario. On my cellphone with an prolonged battery, the phone will drop to 5%, after which proceed to run fantastic for an additional day. So whereas voltage isn’t actual correct, it’s what I watch and I know that when it falls around 3.4v, it’s approaching empty.
Over their lifetime, the utmost useable capability slowly decreases. By periodically topping it off and letting it run right down to where it turns itself off, your phone can study what the new capability is, and thereby providing you with a extra correct percentage remaining indicator. @Sapan, I’m positive the info on this website would apply to all Lithium-Ion cells, including these used by an iphone. My query was….higher for longest lengthy-term life of the battery.
intermittently will this charge the battery, if the battery is first fully charged ? .By intermittent I imply three hour at four.2v , 3 hour at 3.7v , 1 hour at four.2v. Slow charging over night time provides a deeper, more saturated charge, by skipping stage 1 and going straight to stage 2. Admittedly, charging this totally is not optimal for lengthy-term longevity, however provides the most effective run-time without overcharging.
