Hi all. I don't think this has been covered yet, but where is the best (cheapest) place to buy a direct replacement second battery, for my Rad Rhino, with correct connectors etc? I intent to carry this on the rack and just swap over when the first one runs out, on long trips. Rad are charging about 599 euro.

I guess the other way is to buy the triangle battery thing from Bolton bikes? I just bought the upgraded controller and screen from them, but not yet fitted. How much extra lofe over the standard battery will the Triangle battery give over the standard battery?

There is no direct replacement battery for Rad Power bikes.
Rad Power uses proprietary battery case and battery cradle.

However, CitizenCycle (YouTube channel) confirmed that you can just replace your Rad Power battery cradle with Hailong battery cradle, so that you will be able to use the Hailong battery.
You will also need to make sure that connector on battery cradle matches with Rad Power one though, or you would have to solder new connector.

There are so many options with Hailong battery on AliExpress.

Also, EM3EV seems to be the very well trusted battery builder among ebike builders.

Most likely you will just need an adapter

This is the only place where I found a Rad to XT90 adaptor and it has been sold out since like past may or June


I ordered mine in July and still haven't receive it (it is finally en route after almost 6 months).

I did find another website that offers the same adaptor but it is sold out and couldn't get any response from the vendor when I contacted them several times.

If you have been waiting for that long, wouldn't it be easier and faster to just solder XT90 connector to Rad connector?

Thanks for the link.

Thing is I still want to use the regular Rad battery. I am not sure how easily I would have been able to do it after soldering a XT90 connector.

Are you going to be mounting two batteries?

Rad batteries have proprietary battery cradle.
You won't be able to use two batteries because they have different cradle. Unless you're trying to mount additional battery somewhere else.. like rear rack

No I have a spare large battery when I will be touring (like over 150 km (~90 miles)/day) but it is large and cumbersome.

For my commuting, I'll stick to the Rad battery which is only 6 months old (purchased my Rhino this past June).

The plan is to use XT90's on both sides of the connection. From then on, any battery with an XT90 connector will work fine. No more hard to find (or impossible to find) connectors needed.

True, I guess at the end of the day, I was just too intimated to do electronic works.

My bike came with XT60.
Use XT60's. They're good connectors. If given the choice though, I would go with 90's. They're easier for my big paws to get a grip on when pulling them apart....
