? Richtig lesen ! + WARNUNG !
Moin,
Der letzte Link, war keine einzelne Zelle,
sondern eine fertige Batterie.
* 14.8 V 50 Ah pack is made by 4 pcs Power Polymer Li-Ion Cell: 3.7V 50 Ah (15245300C)
* Wrapped by heavy duty Heat shrink tube.
* Two PCM with balance function are installed with the battery pack to protect battery from
* Overcharging beyond 4.25V/cell
* Overdischarging below 2.75V/cell
* Overdrain beyond 80 A Must wait min of 30 minutes after battery is fully charged to allow the pcm to perform balance function on all the cells within the pack.
Hier nochmal: http://www.batteryspace.com/index.asp?PageAction=VIE…
Wenn Du das Geld dafür über hast, nur zu.
Den Zusammenbau aus einzelnen Zellen, überlaß bitte Leuten die sich damit auskennen !!!
Für den Aufbau einer Batterie aus einzelne Zellen,
sollte man „mindestens“ elektrotechnische Grundkenntnisse haben,
um diese richtig zu verschalten.
**Für „Lithium-ion“ Cells, reichen diese „Grundkenntnisse“ aber nicht mehr aus.
Sonst fliegt einem die Batterie schon beim ersten Laden um die Ohren!**

IMPORTANT SAFETY INSTRUCTIONS AND WARNINGS For LI-ION / POLYMER BATTERIES
* You must read these safety instructions and warnings before using or charging your batteries.
* Lithium Polymer and Li-ion batteries are volatile.
Failure to read and follow the below instructions may result in fire,
personal injury and damage to property if charged or used improperly.
* By purchasing Lithium Polymer and Li-ion battery,
the buyer assumes all risks associated with lithium batteries.
If you do not agree with these conditions,
please consider Nimh or Nicd battery or return the battery immediately before use.
* Li-Ion and Polymer battery & packs may explode and cause fire if misuse or defective.
We require all Li-ion batteries & packs buyers must be professionals and have capability to handle emergency.
* Must follow our instruction exactly which is listed on batterypace.com product page to control charging and discharging current.
* When charging Battery Pack, please put battery in a fire proof container.
Please don’t leave battery pack and charger on the wood material or carpet and unattended.
* Must keep Li-Ion & Polymer battery pack away from children.
* If you build your own battery pack by our battery module,
please make sure to charge each module separately by using our smart charger.
The purpose is to keep each battery pack balanced during charging.
The PCB inside will protect this module only.
* Never make wrong polarity connection when charging and discharging battery packs.
Always double check polarity of battery’s connector to make sure red wire to red wire and black wire to black wire.
* Test battery properties is your own responsibility.
Please test Li-Ion battery you bought from us before using or sell to your customer to ensure battery
can be operated preperly and safely in your device.
