jamesd Posted April 30, 2019 Share Posted April 30, 2019 I am new to charging NiMh batteries, I have been charging Lipo batteries for quite a while but never NiMh and just wondering how you program the charger to charge NiMh batteries. I have the OVerlander RC6-VSP charger and it asks for a current limit and NiMH sensitivity d peak. How do I calculate these values? The batteries I am trying to charge are an HPI Plazma 6.0v 1200mah micro pack https://www.modelsport.co.uk/index.php?product_id=378586&gclid=Cj0KCQjw5J_mBRDVARIsAGqGLZBAXrwMXaNvYt21aCzAsx6sFEZ5focJQig05EuMNorGuopAfG2BIxAaAsC8EALw_wcB and an HPI plazma 7.2v 200mah https://www.modelsport.co.uk/hpi-plazma-7-2v-2000mah-nimh-stick-pack-re-chargeable-battery/rc-car-products/385228 Quote Link to comment Share on other sites More sharing options...
Kpowell911 Posted April 30, 2019 Share Posted April 30, 2019 Wouldn’t worry bout the sensitivity, there should be a basic nimh mode and just charge them at 1.2a and 2.0a respectively. 1 Quote Link to comment Share on other sites More sharing options...

Thanks for the reply, ok so similar to lipo batteries. What voltages are considered as low for the nimh batteries? Is there a minimum voltage for them like the lipos?

Nope, theyre alot simpler than lipos, no need for a low voltage cut off or storage charge etc 1 Quote Link to comment Share on other sites More sharing options...

What about over charging do I need to worry about that or will the charger take care of that? Do they need to be fully discharged before re charging?

As guns hinted....caring for nimh batteries is easy Quote Link to comment Share on other sites More sharing options...
Tug Posted May 1, 2019 Share Posted May 1, 2019 They will have a memory effect if you part charge them, they'll need fully discharging before recharging. Storage is usually 0.9 volts per cell. Quote Link to comment Share on other sites More sharing options...
