I noticed that between 4ah and 5ah battery is little difference, but not much, 15% i would say. BUT 5.5 procore seems like 50% better than 4AH bosch battery and at least 15-20% stronger than bosch 5AH battery. When i say stronger, it is noticable in speed,strenght when i cut pellets, or drill concrete, or doing some 100mm or larger screws.
BMW here. No issues.
Tried them all at some point and whatever BMW OE does to those they last 2-3X longer. I literally just replaced a 14 year old battery last September….fuckin insane longevity with the OEM ones.
I used euro car parts 444770127 which is a mid range bosch battery. Don't remember any issues
Bosch, m-a tinut 8ani. Acum tot bosch de 70/75am luat.
I’ve had my iX for 2.5 years and have logged 122k miles. I haven’t noticed any degradation in battery capacity. Just the normal summer/winter fluctuations (live in Midwest).
Bosch - 2.5 years so far,
Varta - 1.3 years before dying
My cargo bike advertises a range of 40-70 miles depending on level of boost. I get up to 40, at the very most, but never more. I use minimum boost only, and usually don’t ride up any major hills. I’ve wonder if this is just grade inflation for marketing or if my Bosch battery was just old/crappy when I got it.
I bought a Bosch battery from a respected online company in the UK. The only change I made was uprating from a 100Ah Varta I think the original was to a 110Ah Bosch S5 015 as I thought more storage would help as the car ages and things are naturally a bit more susceptible to failure. Battery lasted 3 years until about January/Feb 2024 when a cold snap hit and the battery just failed to hold a charge overnight.
I’m not satisfied with the range (70 miles) or the charging speed (max 19.2 kW via J-1772, taking 4 to 13 hours to charge) of the BMW batteries in my Lion Type C electric school bus.
