I have a friend who installed Hipower 300V100Ah battery pack, he had put 496 miles on the pack for one charging.
Just to be clear, the 496 miles were not done on one charge, but many charges between 40 and 50 miles each.

*Ah Major beat me to it.

Looks like a lost in translation thing..

Candy, if you were explaining the differences between the Calb, Thundersky, and Hi-power 100ah cells, what would they be? Why would one buy one above the other?
Thanks
Tom
Tom, thank you for your question, a good question.
And I just can tell you that the single cell are nearly same, but for the battery pack, we can provide all in one solution.
As a Hipower Rep here, I don't make a sale as a purpose here, just make my customers happy, Kevin Constant is my customer, Carl Clark, I have many customer is happy with Hipower cells, just because Hipower has done a lot which can make them happy , thanks for all , we can enjoy the high-quality LiFePo4 battery.

if you feel convenient, you can send the request for 100Ah Spec by Email , my Email adress is [email protected] .
if you want to buy cells, you can buy from Carl Clark, 001-8012435300

If you just post the specs here on the board then everyone can see them.

Thank you. Is each cell tested for actual capacity and internal resistance, do they come with a data sheet with that information, and how close to each other are the cells in capacity? For example, my SE/CALB cells each had a serial number and a data sheet referencing tested capacity and resistance. The 100ah cells all were between 110-114 actual capacity. Closer grouping of capacity would be preferred and make management easier.

hello to all

i would like to offer more input if anyone is looking to purchase a set of hi power batteries, or are just have some questions on how they act or perform under load.

i will try to answer any question to the best of our ability, if we dont know i would be glad to try to find out.

since we have installed our new pack, our weather has been colder, in the 20's in the morning and highs about 45, we have been driving and useing our heater and charging in the afternoon,and all seems to be good. they are charging up balanced and have very good power even when cold.

we are not trying to stand up for any companies past behavior or actions, all i know is what they have done now. they seem to be attempting to make all better. but i will give a piece of advise to hi power " if you trip and fall again,and dont support your customers, your reputation will be completely damaged beyond repair." that will most likely mean no more sales of batteries to the usa ev market.

our ph # is 1-785-233-4750

thanks kevin constant

hello to all

on our new pack we got a test sheet and a serial # sheet. the test sheet showed that the pack had 213 amphr per cell.

thanks kevin constant

Each cells was exactly 213 ah? Do they all discharge and charge to the same value? Have you pulled the whole pack down below 3.0 volts per cell?

hello

no we have taken them that low yet. i was waiting to get a few cycles on them first. but as soon as i do i will tell the world the findings.
because i believe that the truth will make better products.

thanks kevin

Were there any 100 AH Hi-Power batteries sold that were just crap batteries? How many folks here are using Hi-Power 100 AH batteries? How are the holding up? Performing?

PDF says greater than or equal to 1000 cycles. I thought the cells were in the range of 2000 to 3000 cycles, not 1000? Must be confused on this one.

Anyway, Would Hi-Power be a good alternative to TS or CALB in performance and price for the 100 AH size batteries?

Dear JRP3,

This is Kevin from Hipower, very glad to meet you. I would give some suggestion about your question. Batteries would made some extra AH, for high C-rate discharge.. Our engineers would make about 5% to extend 3C continuous discharge, they think it is enough.

Hipower battery is somehow different than Thundersky or CLAB, We use "Aqueous solution" technology, it is more suitable for electron translation in Aqueous liquid, the charge and discharge ability is better than "oily solution", and it is more safe. The "Aqueous solution" is translated as Chinese mean, I don't know the real English word is. However, this improved technology really have better discharge curve, and it is easier to control cell's quality as electrical property of cells in producing, cell would have more "same" property as IR, charge / discharge characteristic.

For battery packs, Hipower select the most same cells to assemble battery pack. We use CLMT (cycling,logging, matching,testing) quality control method. Use machine to pick up cells which have most same IR, as candidate, then do charge / discharge cycles, find out the most same charge / discharge curves, them pick up those cells, to make up battery pack. Our acceptable quality level is : With standard discharge to 80%DOD, the difference of cell's voltage in pack should less than 0.1V. charge to 80%SOC, the difference of cell's voltage in pack should less in 0.1V also.

If you take Hipower batteries, we could offer technical detail support, like fast charging restrict, temperature upping with different C-rate, best discharging condition consider the cycle life. We think no one know our battery than our-selfs, we need to be honest, tell customer what can do or what can not do. Customer is not a battery professor but sales need to be. So the relation is health.

Some useful information:
For all Li-batteries, the best using condition is not totally charged or totally discharged, it due to Li-battery chemistry. So, in 100%DOD can cycle 1000 times, while in 80%DOD can use 2000 times. charge to 3.65V is better than 3.85V to extend the life cycles.

All li-batteries, there is liquid in cell, if temperature is too cold, the electron in liquid would not be easily transported. The capacity would be "frozen", some of capacity can not be fully discharged. when temperature returns to normal, the rest capacity (energy) can be discharged. So design a battery box with heat insulating marital to stop cold temperature effect the battery in winter is better. You may also design some of heating wires to warm cells. For Hipower batteries, when discharging, the temperature would rise about 5 Celsius degree with 0.5C continuous discharge, 10 Celsius degree with 1C continuous discharge.

For fast charging, All Li-battery charging method is CC/CV, and they need balancing time. Hipower battery can take 1C current charing is CC mode, which is 0%~90% SOC, 1C continuous is no effect to cycle life. While for CV mode, which is balancing time, need about 1~2 hours.

I hope it would be helpful.

She asked me to keep it off the forum and I may buy so ill honor that, just to say that its a *bit* less then TS or CALB for what, according to the specs seems like somewhat lower ratings.

She is friendly and fast with a response, hit her up :)

Thank you so much for your frank comments, I like the style. I also do the business in this way, which we can do, then we will tell the customer the truth, we will obey the truth, not like some datasheet, bull shit on the datasheet. as the LiFePo4's physical property, 80% DOD is 2000 lifecycle, and 1000 lifecycle as 100% DOD.
I just can say , High quality is not shown on the paperwork, and it is tested by the enduser.
Thank you !
Candy

I think what you are saying is that your electrolyte is water based as opposed to petroleum, or oil based.

I don't understand why certain sellers like to keep their price a secret. Other places publish their prices and shipping details so buyers can compare.
