Battery Stick Supplier YaBo - Any Good?

mauimart · 09-14-2012, 09:18 PM

Greetings,
Does anyone have any experience with these battery sticks from Yabo Power Technology Co., Ltd.? I was quoted $996 plus $220 shipping for 20 sticks.
Thanks.

Haven't seen this before. Just curious about the voltage rating, as I see better than that with my pack, but the 7.4V may be a nominal rating.

This is one of the many companies that Ron tested. The first problem was the dangerously poor welds. We'll stop there.

It's difficult to match the quality of the Honda sticks. Buyer beware!

I got some sticks from them with much higher price, but the welding seems really strong, I have some photos attached for your reference.

They look about the same as the welds on my sample sticks.

Even if they've improved the welds, the cells themselves are sub-par.

Hi Eli,
I tested the inner resistance are all below 7.5mΩ and no more than 0.2mΩ difference between total 20 sticks, this is almost same as original sticks and much better than those I tested before. So Eli, can you upload any evidence how you judge they are using sub-par? I will tell them about your opinion and see what they say.

I've been in contact with them for some time. They keep asking me to buy their product.

Capacity and internal resistance are both worse than my current offering.

Interesting. Welcome to the forum! Please post your location in your profile so fellow local owners can connect with you.

The Inner resistance of 6 normal D6500 in serial is more than 25mΩ, and if it's sub-par, the inner resistance should not be less than 40mΩ. With 7.5mΩ inner resistance no more than 0.1mΩ up and down for total 20 sticks, this is already the best figure I have ever seen except original sticks, so I think they are doing fine.

Is internal resistance some kind of tell-all metric for the quality of batteries/sticks?
