Electric Bicycle

[luckyluke]

I have a Tunited FS-313 Electric bicycle (similar to this)

I need a new battery, I contacted many times(@mail & telephone-English & Thai) the company in Bangkok without any results(no any answer)

Do someone know where I can find a 36V12 AH battery in the Pattaya-Jomtien-Naklua area please.

Many thanks.

what type of batteryis it?

SLA

Lithium

Ni-Mh

if its a Lithium your in trouble....if you dont find that its a lithium or ni-mh you can use three SLA 12 volt batteries connected in series to obtain 36 volts, these are commonly the batts used in computer UPS systems, then you will have to purchase a battery charger..since lithium chargers only work with lithium.

if you dont know what type of battery it s..a lithium batt usually has something like 3s1p written on it somehwere, lok for the 's' and 'p' designations.

if its a Lithium your in trouble....if you dont find that its a lithium or ni-mh you can use three SLA 12 volt batteries connected in series to obtain 36 volts, these are commonly the batts used in computer UPS systems,...but your range will drop about 50% since the power density s lower than lithium...

then you will have to purchase a battery charger..since lithium chargers only work with lithium.

if you dont know what type of battery it is..a lithium batt usually has something like 3s1p written on it somehwere, look for the 's' and 'p' designations....for a 36 vot lithium it would be something like 10s1p...3p if your lucky, this will have 3 times the amperage of 1p.

if you wanted to simulate the performance of a lithium setup, you could simply use 6-9 batteries and install them on the back rack and have even greater range and torque than before....you would connect 3 in parralel, then connect the top 3 in series...this would give you 36 volts 36ah..if you were to use 12ah batts.

if you do find the original replacement battery, be prepared to spend no less than 10,000 baht.

Can you peddle it in the meantime?

how is the bike overall? current battery troubles notwithstanding
