I've gained much joy (and about 2000 kms) out of my electric bicycle. I've also spent a small fortune on it, and experienced a huge amount of frustration because it's so hard to find reliable suppliers.
I am now awaiting the return of my 3rd LiFePO4 battery... It's being serviced under warranty somewhere in Taiwan, and I'm now told it won't get back to me for another month.
I'm not confident that it'll be any better than it was, if and when it gets here...
I have a 500W brushless motor kit installed on a Mongoose Hybrid commuter bike which, when it goes, is fantastic (though a little heavy).
I want to buy a decent back-up battery, and am nervous of getting another el-cheapo rip-off from eBay that will crap itself the moment it gets out of warranty, as has already happened to me twice.
Can someone PLEASE recommend a reputable OEM (original equipment manufacturer)that isn't attempting to make a 500% margin..., or should I build my own battery pack using DeWalt batteries? If so, is there a good BMS for protecting them?/A way the pack should be configured? Also, and finally, does the DEWALT NANO BATTERY 18Volt LITHIUM ION DC9180-XE contain LiFePO4 at all???
I suspect I may have to remain frustrated for some time, or fix this sordid business for myself??!
