EM3ev doesn't seem to even sell a Dorado compatible battery?
No argument with EM3ev being a supplier you trust, but Jenny and Aujiu's batteries are used in 1000's and 1000's of ebikes, scooters, etc. Selling direct to users is a side business for them, they sell wholesale to bike and scooter companies mainly. I have a lot of confidence in them and Jenny is fantastic to deal with.

I'm sorry, but I don't buy the claim. BTW I do have a battery from her. It lacks the sophistication other makers sell. It's performing well.

My former shop lost THOUSANDS on a payment scam. Leaving me with a loss of trust. Let me ask you this: if a seller does thousands of builds, why bother to sell here?

Hi Bitmugger

Thank you for your reviews, I‘m interested in purchasing one for myself. But I‘m wondering about waterproofing. I ride all year, even in heavy rain, and up to an hour per ride. So the battery is exposed to quite a lot of moisture. I now have a dorado max battery from frey bike and it holds up well. I opened it up recently and after almost 4 years of use, there was some minor corrosion on the plug, connecting the battery pack to the power outlet.

Can you say anything about your batteries? Have you used them in rain too? Are they probably comparable?

Thanks and cheers

My son rides all year winter (snow) and summer. He has some Aujiu's batteries and they've served him well. We haven't opened them up though. I have opened my battery the 25ah and it has seals and such as was fine inside, We've biked 2 Aujiu's batteries in a hurricane once as we were on a multi-day trip and got caught needing to make a ferry while the hurricane was on us. I've also ridden in the wet many time but rarely set out in the rain, just get caught in the rain. That's about the best I can offer for experience.

I have two older style Dorado DP9 52V, 20ah batteries that get used in the rain occasionally. The DP9 case isn't waterproof but I've never had a problem with corrosion in the past. If there's rain in the forecast, I stretch an old shower cap over the battery or apply plastic wrap around the downtube and battery. I can still operate the switch and see the charge level gauge through the clear plastic.
