oh man... for every 10 UPP success stories there seems to be one that ends in tears. Usually revolving around the actual capacity of the battery being nowhere near what was advertised, coupled to customer service either putting return ship charges on the customer - to going completely unresponsive. Plus the rare fires. Rare but not unheard of. Not the kind of success ratio I would tolerate for something so critical - and dangerous - as a battery.
If Cali Ebike can't get more than 17ah into it and using 35E's to boot, then UPP is doing something naughty. Be it fibbing about the capacity, or doing without the internal framework so they can stuff a few more cells in at the expense of safety/durability. You have to wonder how only a 13S6P battery can make that much capacity. The Samsung 35E in the 17ah Cali battery is a 3500mah cell so what could possibly beat it in capacity in an 18650? UPP isn't saying.
My standard smartass UPP admonition is "Every time someone buys a UPP battery, God kills a kitten."
Hello Tom
I am really sorry the problems for you.
Normally my email now is replied by my assistant because i become busy and busy so no time to reply all the email.
I think that is why you and customer think our reply is slow now.
I do not know have so many problems for you.
In the past years i really very grateful you introduce so many customers to us.
For the BMS,we did not use balancing function that is because many battery case have a place to put the balancing BMS because the balancing BMS size is very big.
And all our BMS will have temperature monitor in future.
For the nickel some customer need it pure but some customer not need,tell the truth pure nickel will increase the cost a lot.
But many customer can not pay the high cost for the pure nickel,as you know we are not only retail we also cooperate with many ebike factory,and they need a competitive price.
Anyway,i really sorry our not good service for you now.
Can you let me know what we can do for you now?
If you need any new BMS let me know,and if you want any new battery also let me know.We hope we can get more advice from you,and i really want you my friend as before.
