vortex666 Posted August 27, 2013 Share Posted August 27, 2013 Hi guys,does anybody knows what battery pack should i buy for hpi trophy truggy receiver pack instead of buying 4 batteries?Thanks Sent from my iPhone ? using Tapatalk Quote Link to comment Share on other sites More sharing options...
J.K Posted August 27, 2013 Share Posted August 27, 2013 Hello chap, I'd recommend this one http://www.modelsport.co.uk/hpi-plazma-6.0v-1600mah-nimh-receiver-pack-re-chargeable-battery-3-2-hump-style/rc-car-products/363459 Or any other pack with the cells arranged in a 3+2 configuration should suit. You'll need a charger to go with it tho! The difference between running one of these over AA's is night and day Quote Link to comment Share on other sites More sharing options...
Mar_k Posted August 27, 2013 Share Posted August 27, 2013 I have just fitted one of these to my HPI pulse, They are awesome. The torque in the steering now is great. Buy a decent peak charger as the crap trickle charger I bought is only 80a, it takes 32hours to charge from new. Quote Link to comment Share on other sites More sharing options...
PastyPowered Posted August 29, 2013 Share Posted August 29, 2013 It doesn't look like these will fit in my cars 4xaa battery compartment? Can anyone advise? Quote Link to comment Share on other sites More sharing options...
Shudson Posted August 29, 2013 Share Posted August 29, 2013 It doesn't look like these will fit in my cars 4xaa battery compartment? Can anyone advise? It replaces this sort of thing. http://www.modelsport.co.uk/traxxas-battery-holder-4-cell-no-on-off-switch-/rc-car-products/377047 Usually a plug between it and switch. Just unplug battery holder and replace with hump pack. Sometimes holders are hard-wired to the switch, in which case you may need to replace switch as well. If you have a built-in moulded battery tray (toy grade models, usually), you are probably stuffed! Quote Link to comment Share on other sites More sharing options...
PastyPowered Posted August 29, 2013 Share Posted August 29, 2013 Thats great thanks. However looks like my battery and receiver holder is one single unit. Quote Link to comment Share on other sites More sharing options...
DeadMeatUK Posted August 29, 2013 Share Posted August 29, 2013 It's probably too much effort, but what about using a Lipo and BEC? Nimh packs are a pain as they self discharge. I use a 2s Lion pack with BEC and lasts weeks without charge Quote Link to comment Share on other sites More sharing options...
DreXeL Posted August 29, 2013 Share Posted August 29, 2013 (edited) There's no need for a BEC if you use a LiFe pack, as they have a lower voltage than LiPo (6.6v nominal). This is slightly above a NiMH but still well within the tolerances of most receivers and servos. I run one in my Savage and it's fantastic, I only have to charge it occasionally. Make sure you have a compatible charger though. Here's the one I use: http://www.ebay.co.uk/itm/6-6v-1600mAh-LiFe-RX-Battery-Vapextech-Hump-/220888943885 Edited August 29, 2013 by DreXeL Quote Link to comment Share on other sites More sharing options...
HYPER-BOY Posted August 29, 2013 Share Posted August 29, 2013 I use the above mentioned packs in my cars. Awesome things! Got mine from wheelspin with a 2/3 hr charger. The pack is alot smaller than it looks and is actually smaller than the 4xAA holder it replaces. Quote Link to comment Share on other sites More sharing options...

They sell a blue rx pack. Straight swap for 4 AA. miles better! Quote Link to comment Share on other sites More sharing options...

fatboyneil Posted September 2, 2013 Share Posted September 2, 2013 You could have kept it on it still fits you just have to make sure the plug is the right way round now with what you've done there is not safe the connections are exposed leaving it capable of shorting out while charging Quote Link to comment Share on other sites More sharing options...
