All LRP VTEC LiPo-batteries (except the RX/TX-packs) are capable of a maximum peak dischar-
ge current of 25C. The special manufacturing technology of the LRP VTEC LiPo-batteries make
these high discharge currents possible.

All LRP VTEC LiPo-batteries can be charged with a maximum current of 1C*. For charging, only
use chargers, which are specially designed and developed for LiPo-batteries. These chargers
charge the battery with the max. current till the battery reaches the max. charging voltage. The
charger then reduces the charging current until the battery is fully charged.
Under no circumstances use NiMH/NiCd-chargers for charging LiPo-batteries!
These chargers do not reduce the charging current and therefore ultimately lead to overcharging
LiPo-batteries do not heat up dur

ambient temperature when it is fully charged. If the battery heats up dur

LRP VTEC LiPo-batteries do not have a memory effect and
only a very low self-discharge rate.
Therefore you can also charge batteries with a partial charge in them, without the need of
discharging the pack before.
Partially charged packs can be stored over a long period of time, without getting damaged.

You can use your LRP VTEC LiPo-battery several times a day. However be sure,
that the battery has completely cooled down to ambient temperature, before re-charging it

5. CHARGING REPAIR PROCEDURES /
LIMITED WARRANTY
All products from LRP electronic GmbH (hereinafter called “LRP”) are manufactured according
to the highest quality standards. LRP guarantees this product to be free from defects in materi-
als or workmanship for 90 days (non-european countris only) from the original date of purchase
verified by sales receipt. This limited warranty doesn’t cover defects, which are a result of misu-
se, improper maintenance, outside interference or mechanical damage.
on already used batteries or batteries, which show signs of heavy usage. Damages or output
losses due to improper handling and/or overload are not a product fault. Signs of wear (loss of
capacity) after intensive usage are also no product fault.
To eliminate all other possibilities or improper handling, first check all other components in your
model and the trouble shooting guide, if available, before you send in this product for repair.
If products are sent in for repair, which do operate perfectly, we have to charge a service fee
according to our pricelist.
The following points do also result in a service fee:
Original power plugs replaced with a NON reverse polarity protected power plug system.
Send in the battery without power plugs.
Removed or damaged original heatshrink.
With sending in this product, the customer has to advise LRP if the product should be repaired
in either case. If there is neither a warranty nor guarantee claim, the inspection of the product
and the repairs, if necessary, in either case will be charged with a fee at the customers expense
according to our price list. A proof of purchase including date of purchase needs to be included.
Otherwise, no warranty can be granted. For quick repair- and return service, add your address
and detailed description of the malfunction.
If LRP no longer manufactures a returned defective product and we are unable to service it,
we shall provide you with a product that has at least the same value from one of the successor
