The higher the amp hours — e.g., 14Ah vs. 25Ah — the more “fuel” your bike will have and the longer it’ll be able to run. A bike with a 25Ah battery will have nearly twice the range of an identical bike with a 14Ah battery, so long as they’re driven in the same fashion. Range

WebIf the battery reaches the end of discharge voltage at the same time as the specified test time ends, the battery’s measured capacity is 100 % of its rated capacity. If it reaches the end of discharge at 80 % of the specified test time or sooner (e.g., at 8 hours of a 10-hour test time), you should replace the battery. WebAt the same time the battery voltage will rise due to the charging current. When battery voltage reaches 8.4V the charger will progressively lower the charging current to prevent the voltage from going higher than 8.4V. The LT3741 itself is not a battery charger.
