WTS: First Hand Batteries
#31
Thanks adrian and mark for speaking out for me here, I didn't expect there will be anyone who will speak out... I really appreciate the thought... Initially, I thought that it is because the battery is not charged in the correct manner, causing low capacity problem. But as some of my customers pointed out, they have formed-charged and charged the batteries according to the instructions given online, and yet still unable to get the right capacity... So I suspect the different batches of batteries might be the problem... Cos I have another batch of customers who have no problems at all... But the later batch is giving some problems... I have learnt my lesson... I guess my first try at doing a small online business have failed. Other than the low capacity problems, the voltage and power of the battery have no issues right? Because I just measured using the multi-meter on random batteries and its around 7.2V plus minus. The power is around 12C as indicated. I suspect the manufacturer marked-up the actual capacity and sell a 2000mah as 3800mah maybe? Condemn the manufacturer!
I should have informed my customers that the first thing to do to a nimh battery is always to form-charge it few cycles to bring up the capacity to maximum, before using on the rc car... The moment it is fast-charged, the battery capacity will drop drastically... and since the battery is so cheap, i believe the effect might have permanently damaged the battery cells...

Anyway, lesson 101 for buying from suppliers: "Buy cheap, buy twice".
Lesson 102 from China/HK cheap suppliers : "Standard MO is to give first batch or 2 good quality, then subsequently when you have trust in them, they will cheat you."

Battery very hot after use
Just 1 more thing i want say about the battery , is tat its heat produce out very hot(almost same heat produce with my 1800MAH NICD after use) , maybe becoz of the wrapping?coz most other brands use 'carbon' wrapping , maybe slow conductor of heat??
Just my feedback...
Just my feedback...

Just last question(not trying to spam as i was eating my breakfast as recall)
Coz before i brought frm u i keep asking is there 3800 MAH as i heard my people saying there alot of batteries are capcity are lower than the rated by alot , maybe u thought i was meaning the overall 3800 +- 10% of batteries capcity , and i am sure u didnt knew tat tis batteries 'ingredients' was cut down to half , as u dun have a 'check battery current capacity charger' , and u also say tat u try in b4 in first batch very good , but 2nd batch alot prob , becoz u dunnoe mah so cant blame u =)
As what i learnt when i was looking for batteries tat , based on what i see(just my opinion)...
Talking about the capacity , not the power
1.First shop owner i go in and ask , i ask for a 3000mah(as i was looking ard tat capacity) he shown me the first 1 branded , 3000mah , but price abit high , den i ask got cheaper one ma?he say have of coz! He show me another one no brand one oly got 1 label 3000mah den he told me tis cheaper one . 'but not original, he explain to me whats the meaning , and he told me tat stated 3000mah , customer come in say 1 cheapest '3000mah' i sell him tis one , Shop owner: '3000mah what , but we dunnoe inside is 2000mah?1500mah?1000mah?so is best to buy original(branded) he said...
2.My 2nd RC car partner , i called him, : he say tat there no such tink original , or no original , just the capcity inside(same as shop owner saying...)
3.MY 1st rc car partner , i called him , Ask him about my NICD battery y so fast finish , he told me tat NICD batteries comfirm dun have the rated one for the type of chemical , and its true , my new victory hawk 1800 mah , charge full oly 1.2k mah most.And of coz the price so cheap ,brand new 2000mah can get for oly less than $20...
Just what i see about batteries , not to have impact or war with anyone... ar

Hi bros, the fellow who sold me the batteries cannot be contacted. Thanks for giving me the chance and time to re-correct the issues. I have decided to discuss possible solutions to solve this issue. That damned fellow did not reply me and there is no way he will refund me for the time being.
Dear customers, pls PM me your HP number (I already have a record of the batteries sold) and I will contact you and discuss the the refund options on case by case basis.
Whatever profits I made will be given back and the solutions will be reasonable to both parties. Thanks alot...
The batteries actual capacity are roughly about 60% of the indicated value from the feedback and testings i have conducted.

Bro, what's the use for refund.. But if people really can't use it fine can be refund.. we are all doing a living here.. Its just people with their hobby.. I know sometimes people get frustrated on matters like this.. But lesson learn bro.. I myself bought 2 of your batt with chaos7727 and i dun really care about the capacity as long as my RC can run to practice and thats fine with me.. but when in competition i use my orion batt and your batt is just for a back up..
Good luck bro with it.

yep, be careful with china suppliers in the future... its a very common stunt they pull, first batch solid, future batch all chui..
happen to deans plug i was importing as well. which is why i stop selling stuff. too much of a hassle (i tested my second batch and decided not to sell any of them) to manage risks and got uni to concentrate on :P..
but i think this is a super painful lesson for TS, those who bought things from him hope all can be understanding. good luck
